RVM Ruby installation not successful - ruby

I'm trying to install ruby using rvm on linux debian. This is my problem:
Ruby didn't work at all in the terminal (that is, it said: ruby:command not found.
Then I followed this thread RVM ruby installation issue and it worked. However, after I closed that terminal and opened a new one, it didn't work anymore.
Do I have to change something in the autostarts? Can someone please help me!!

Check if your ~/.profile file contains:
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
and your .bash_profile file contains:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
if it have it and still don't work add this line to your ~/.bash_profile
source ~/.profile
I'm assuming you are using bash as your shell. You may want to check it in your user preferences (depend on your distro).

I assume the installation worked, what did not worked is you missed to use the installed ruby:
rvm use ruby-2.1.0
in your case it would print you a warning about not using login-shell - follow the instructions, they ae there to help you

Need to Fix PATH in my bashrc File for RVM

I did a clean install of my operating system recently and copied my old .bashrc file from a backup. I installed rvm version 1.26.10 (latest stable version). I installed ruby 2.2.0. When I source the .bashrc file I get the following error:
Warning! PATH is not properly set up, '/Users/myusername/.rvm/gems/ruby-2.2.0#mygemset/bin' is not at first place,
usually this is caused by shell initialization files - check them for 'PATH=...' entries,
it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
to fix temporarily in this shell session run: 'rvm use ruby-2.2.0#mygemset'.
Here are my PATH statements. The first line I included here is one that was in the new install of RVM in the .bash_profile file. I copied them into .bashrc. I'm also running postgres.app which requires the last statement in order to set it as the current PostgreSQL instance.
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
PATH="$PATH:$HOME:/.rvm/rubies/ruby-2.2.0/bin/ruby:/usr/bin/psql:/usr/local:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin"
export PATH="$PATH:$HOME/.rvm/bin"
export PATH=/Applications/Postgres.app/Contents/Versions/9.4/bin:$PATH
I started with the .bashrc file recommended by the Ruby on Rails Tutorial by Michael Hartl (the version current in 2011 or 2012) and the settings used by RVM back then. I know things have changed a bit since then.
My bash knowledge is limited so any help would be appreciated.
UPDATE: 2/2/2015 2:40 pm CST
I changed my bash statements to the following and got rid of the warning:
export PATH="$PATH:$HOME/.rvm/bin"
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
PATH="$PATH:$HOME:/.rvm/rubies/ruby-2.2.0/bin/ruby:/Applications/Postgres.app/Contents/Versions/9.4/bin:/usr/bin/psql:/usr/local:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin"
UPDATE: 2/2/2015 5:14 pm CST
Here are my Bash statements:
PATH="$PATH:$HOME:/.rvm/rubies/ruby-2.2.0/bin/ruby:/Applications/Postgres.app/Contents/Versions/9.4/bin:/usr/bin/psql"
export PATH="$PATH:$HOME/.rvm/bin"
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
Here is the output for echo $PATH:
/Users/username/.rvm/gems/ruby-2.2.0#gemsetname/bin:/Users/username/.rvm/gems/ruby-2.2.0#global/bin:/Users/username/.rvm/rubies/ruby-2.2.0/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Applications/Server.app/Contents/ServerRoot/usr/bin:/Applications/Server.app/Contents/ServerRoot/usr/sbin:/Users/username/.rvm/bin:/Users/username:/.rvm/rubies/ruby-2.2.0/bin/ruby:/Applications/Postgres.app/Contents/Versions/9.4/bin:/usr/bin/psql:/Users/username/.rvm/bin
My RVM wouldn't stop complaining about PATH even though the last thing in my .bashrc was this line:
# RVM
source ~/.rvm/scripts/rvm
So I just redirected the complaining to /dev/null:
# RVM
source ~/.rvm/scripts/rvm > /dev/null 2>&1
rvm use default > /dev/null 2>&1
The last line also makes sure RVM is first in PATH, so it doesn't really have anything to complain about.
rvm expects its $PATH stuff to come first in $PATH. You should add items to the $PATH before sourcing rvm, not after.
After dealing with this for several days I decided to go ahead and continue to proceed with my implementation of postgres.app with the warning message I got with RVM. I ran my original bash statements in a different order.
export PATH="$PATH:$HOME/.rvm/bin"
PATH="$PATH:$HOME:/.rvm/rubies/ruby-2.2.0/bin/ruby:/usr/bin/psql:/usr/local:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin"
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
export PATH=/Applications/Postgres.app/Contents/Versions/9.4/bin:$PATH
I was successful in implementing postgres.app. I still get the warning message but my Ruby on Rails applications are able to find the correct gems and run successfully.
You should add the line like this
export PATH= '/Users/myusername/.rvm/gems/ruby-2.2.0#mygemset/bin:other"
Maybe that can help you

rvm on OS 10.9 a few problems: second export path to .bash_profile, missing 2.0 path, and missing files

1)
I have this error every time I load a new bash terminal
-bash: /etc/profile.d/sm.sh: No such file or directory
-bash: /etc/profile.d/rvm.sh: No such file or directory
I saw this previously asked question with the answer to simply delete the references from .bashrc. But the answer is unaccepted and unvoted and the references to these files are not in .bashrc but in ~/etc/profile
I should note that I don't have a profile.d directory under /etc. I have files profile and profile~orig
2)
RVM added a second export path after I ran rvm get stable, but did not include a reference to Ruby 2.0.0 in either.
.bash_profile
export PATH=$PATH:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
export PATH=/usr/local/bin:/Users/mcb/.rvm/gems/ruby-1.9.3-p448/bin:/Users/mcb/.rvm/gems/ruby-1.9.3-p448#global/bin:/Users/mcb/.rvm/rubies/ruby-1.9.3-p448/bin:/Users/mcb/.rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
My instinct is to combine them into one, eliminate repeats, and add the references to ruby 2 manually. I also added the $PATH: myself, since that didn't work the first time either.
3)
This is clearly not right
my-macbook-pro:~ mcb$ rvm get sable --auto-dotfiles
Warning! PATH is not properly set up, '/Users/mcb/.rvm/gems/ruby-2.0.0-p247/bin' is not available,
usually this is caused by shell initialization files - check them for 'PATH=...' entries,
it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
to fix temporarily in this shell session run: 'rvm use ruby-2.0.0-p247'.
cat: /Users/mcb/.rvm/help/get: No such file or directory
So, long story short I'm starting to get worried about trying to fix anything else myself without some sort of guidance for fear of just making things worse.
for 1) check /etc/profile for those two files references
for 2) remove export PATH=/usr/local/bin:/Users/mcb/.rvm/gems/ruby-1.9.3-p448/bin:/Users/mcb/.rvm/gems/ruby-1.9.3-p448#global/bin:/Users/mcb/.rvm/rubies/ruby-1.9.3-p448/bin:... from ~/.bash_profile
for 3) rvm get sable => rvm get stable
I think the problem is that you are adding ruby 1.9.3 explicitly in your PATH, and that's a job that rvm shoud do.
In my case I have no direct reference to any of the ruby installations in my PATH.
Try cleaning your path from anything ruby and rvm related, and let rvm load as a function.
This is the .bash_profile on my computer (with rvm and brew working):
export PATH=/usr/local/bin:/usr/local/sbin:$PATH:/usr/local/opt/ruby/bin
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
To check if rvm is correctly configured you can run:
type rvm | head -n 1
The result should be: "rvm is a function"

How to permanently switch ruby -v 1.8.7 to 1.9.3

By using these commands
source ~/.rvm/scripts/rvm
rvm use 1.9.3 --default
The version in current session is 1.9.3 but when I close terminal and reopen ruby version comes back to 1.8.7.
Do I need to add something to the .bash_profile ?
Edit: I found the another way is when I reopen terminal everytime just type source .bash_profile. The version then is 1.9.3. Is there anyway to execute the .bash_profile permanently ?
Yes you need to add something to your bash profile. See here:
https://rvm.io/rvm/basics/
Quote:
The rvm installation documentation instructs you to put the following line at the very end of your bash profile:
# This loads RVM into a shell session
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
Create a file named .rvmrc with the text rvm use 1.9.3 --default.
We're treading into sysadmin waters here but one possible explanation might be because of how you're logging into your shell and your OS. See the discussion of what files are loaded by your shell here and what makes up a login vs. non-login shell here.

rvm installation not working: "RVM is not a function"

I just installed RVM, but can't make it work. I have such line at the end of my .profile file:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
I tried to run source .profile and restarting terminal, but still, when I run rvm use 1.9.2 I'm getting:
RVM is not a function, selecting rubies with 'rvm use ...' will not work.
My system is Ubuntu 11.10.
You need to run the following
$ source ~/.rvm/scripts/rvm
then run this
$ type rvm | head -n 1
and if you get
rvm is a function
the problem is solved.
You also need to run user$ rvm requirements to see dependency requirements for your operating system
Source: https://rvm.io/rvm/install/
I forget mention that you need to put this code into you ~/.bashrc or ~/.zshrc file and you will not need to write this code again.
You are not using an login shell.
The process of enabling the login flag is described here, also some details on what a login shell is can be found here.
Thus, you need to check the option "Run as login shell" in the Gnome terminal's settings. It is required to open new terminal after this setting the flag.
Sometimes it is required to set the command to /bin/bash --login.
For remote connections it is important to understand the differene between running interactive ssh session and executing single commands.
While running ssh server and then working with the server interactively you are using login shell by default and it's all fine, but for ssh server "command" you are not using login shell and it would be required to run it with ssh server 'bash -lc "command"'.
Any remote invocation can have the same problem as executing single command with ssh.
To permanently resolve this just cut/paste following line:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
From: ~/.bash_profile file
To: ~/.bashrc file
Reason this works is that .bashrc is executed each time you enter the terminal, and .bash_profile each time you login. That is why solution /bin/bash --login works, but you have to do that each time you enter the terminal. This way you are set until your next format, and you will forget all this by than :)
I too faced this problem. Finally i executed this line on terminal.
source ~/.rvm/scripts/rvm
Problem is fixed. Because this line will make the RVM instance a function for a particular time.
The latest RVM (rvm 1.11.6 (stable)) stopped working on Ubuntu (10.10 - 64 bit - nerdy gnat or whatever) - I kept getting
"RVM is not a function, selecting rubies with 'rvm use ...' will not work."
Before, I got the message, but 'rvm 1.9.3-p0#rails321' would work. Now, it wouldn't work - you couldn't change gemsets at all.
Nothing worked, until I found this - make this the LAST line in /home/your-name/.bashrc
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
As you said, the error shown could be the following one.
RVM is not a function, selecting rubies with 'rvm use ...' will not work.
You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.
As said above, just type '/bin/bash --login' in your terminal (after restarting your terminal), then type the comand 'rvm use 1.9.3' (for e.g.) and it will start using the same version.
Just execute the command 'ruby -v' to confirm that the RVM is using the updated version of Ruby.
I had this problem too on a fresh rvm installation, and non of the answers here fixed it. Going into the official rvm site, on the basics section, they have this command:
# from http://rvm.io/rvm/basics
source $(rvm 1.9.3 do rvm env --path)
You should change 1.9.3 for the ruby version that you actually want, and it'll make rvm a function regardless of the shell type.
even though you accepted an answer, i'd like to suggest another way .. ~/.bashrc is loaded before any shell is opened. Add that line at the end of that, and you don't need any of that login shell thing
Maybe you can try belows:
Your Terminal ->
Edit ->
Profile Preferences ->
Title and Command ->
Check the "Run command as a login shell"
Done
Run bash --login and then run rvm use 2.0.0.
Open Up the Terminal and then Go to Edit > Profile Preferences and then go to the Tab "Title and Command" and Check "Run Command as Login Shell".
Boot Up a Bash and Now you can install Gems directly from the terminal without the use of sudo and the error "RVM is not a function, selecting rubies with 'rvm use ...' will not work." will be eliminated.
Cheers.
All the above answers are valid. But when i faced the same issue, the solution was the following:
Update ZSH. (Tried to update directly din't work for some reason. So uninstalled and reinstalled updated version from here)
Set default shell as zsh (i.e. if you prefer zsh) using sudo chsh -s $(which zsh) $USER
Ensure that the following code is at the bottom of your .zshrc after you have installed the latest RVM probably using CURL from official RVM site
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
source ~/.profile
MOST IMPORTANT POINT: Ensure that in your .zshrc file every export to PATH is appended with :$PATH. Which i believe was the root of my problems even after following the above steps.
post this all my problems of RVM Not being a function went away. If it still does not work, give some error trace over here. After a few hours of struggle to solve this issue, i'm sure i must have seen all related errors.
Hope it helps. Cheers!
Procedure for installing Ruby 1.9.3-p125 on Mac OSX 10.8 Mountain Lion
You've already installed the latest XCode (>= 4.3) and and the command line Objective-C
compiler "clang".
You must run the "bash" shell for this procedure to work.
Go to System Preferences
Click on "Users & Groups"
Click the lock on the bottom left of the panel and enter your password to unlock it.
"Ctrl-Click" on your user icon in the left pane of the panel and choose "Advanced Options..."
Change the Login Shell to "/bin/bash"
Close the preferences
Open a terminal window (press command+spacebar and type in "terminal")
Follow the instructions at:
http://www.frederico-araujo.com/2011/07/30/installing-rails-on-os-x-lion-with-homebrew-rvm-and-mysql/
Notes:
To install ruby, you may need to specify the clang compiler:
$ rvm install 1.9.3p125 --with-gcc=clang
If RVM gripes about /usr/local/rvm not found, you need to create a link:
$ ln -s /Users/[your user name]/.rvm /usr/local/rvm
source ~/.bash_profile
... should do the trick ..., probably need to logout and login again.
How to reload .bash_profile from the command line?
I'd got the same error because I'd ever installed the old rvm version ruby-rvm with the apt-get command.
I solved the problem by remove the script line to config the old rvm in .bashrc file.
Check the old rvm config script and then run source .profile
« Official » instructions are there: https://rvm.io/integration/gnome-terminal/
I fixed it by adding this line to .bash_profile:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
I had the same error, but none of the solutions on this page seemed to work. For me it was enough to add the rvm executable to my path:
PATH=$PATH:/usr/local/rvm/bin/
Et voila!
I had the same issue and I did this in my .bash_profile and it worked.
source "$HOME/.rvm/scripts/rvm".
For those who comes with same issue and they are using lubuntu like me I followed this link :
You start your terminal with
lxterminal -e "bash -il"
Thank to #mpapsis who pointed me to the right direction
My unclean way to change of ruby version is
rvm alias create default ruby-2.2.3 && source ~/.bashrc && rvm list
it works because I have the line bellow in my ~/.bashrc but strangely it don't do the job automatically.
[[ -s "/usr/local/rvm/bin/rvm" ]] && source "/usr/local/rvm/bin/rvm"
I tried to connect with --login to my docker container
docker run -it imagename `/bin/bash --login`
but in this case the container stay open in background and I can't enter commands.
I tried both zhc and terminal with the option "open with /bin/bash --login"
$ source ~/.rvm/scripts/rvm
if you don't want to do it again and again for every terminal tab enable the login shell by following these steps.
got to preferences
enter image description here
enable run command as a login shell

OSX Lion New bash session rvm default ruby not used

I use OSX Lion. I have installed RVM and have put this line in my .bash_profile file.
[[ -s "/Users/Anand/.rvm/scripts/rvm" ]] && source "/Users/Anand/.rvm/scripts/rvm" # This loads RVM into a shell session.
I installed ruby-1.9.2-p290 and set it as default rvm ruby with this command:
rvm use --default ruby-1.9.2-p290
And when I checked ruby-v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.2.0]
The problem is, every time I open a new terminal window or a tab, the default ruby is not getting set. The system ruby is instead getting used. ruby -v gives this:
ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin10.3.2]
This also happens with reading .rvmrc file in a ruby project. When I'm inside a project and when a new tab gets opened, it gets me into the project directory but is not setting ruby according to .rvmrc in that project. What should I do to fix this?
I got the problem. It was with $PATH. I have to put rvm related line in the .bash_profile as the last line.
Old .bash_profile
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
source $HOME/Dropbox/dotfiles/bashrc
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
export PATH=/Library/PostgreSQL/9.0/bin:$PATH
New .bash_profile
source $HOME/Dropbox/dotfiles/bashrc
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
export PATH=/Library/PostgreSQL/9.0/bin:$PATH
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
And it worked. New windows and new tabs open up correctly with the default ruby i.e, ruby 1.9.2
I just fixed this very same issue. Turns out it was a path issue.
try this
➜ ~ which ruby
if you are getting /usr/bin/ruby, the path to your original ruby installation is overshadowing the default install in your RVM installation.
I added the path to RVM before the path (see below) to /usr/bin/ruby and it works as expected.
I use zsh as my shell, so I had to add this manually to my .zshrc
export PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting<br />
export PATH=$PATH:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
if you use bash
Your .bashrc probably looks like this
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
change it to this:
PATH=$HOME/.rvm/bin:$PATH # Add RVM to PATH for scripting
and make sure you .bash_profile has this:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function
and you should be good to go.
Of course this means that your shell is going to look in your RVM directory first when looking for any command, but thats never caused any issues for me.
Question #1:
The command as listed is, you had switched '--default' and 'use'.
rvm --default use ruby-1.9.2-p290
Check if default is actually set:
$ rvm list default
Default Ruby (for new shells)
ruby-1.9.2-p290 [ x86_64 ]
Some other troubleshooting tips in case that doesn't work. Are you sure your bash profile file is being loaded? Try just having 'source "/Users/Anand/.rvm/scripts/rvm' instead of the check, maybe something is wrong with the path? Username does that begin with capital letter?
Question #2: You must cd into the directory with the .rvmrc file explicitly for the magic to happen. I suppose starting a console in a certain location doesn't trigger rvm. I run into this when using pushd and popd to switch between folders.
Try this first if rvm --default use doesn't work:
sudo rvm alias create default 1.9.2
