Each time I open a terminal my Ruby version is wrong. I am obliged to execute by hand the following command:
source /usr/local/rvm/scripts/rvm
I read that RVM doesn't modify .bashrc or .bash_profile but I note that my .bashrc has at the end:
PATH=$PATH:$HOME/.rvm/bin
Not only I didn't insert this myself but the path to rvm is wrong !
I changed by:
PATH=$PATH:/usr/local/rvm/bin
I reopened a terminal but the Ruby version is always wrong !
rvm does modify your .bash_profile / .bashrc -- that's one of its weaknesses. In particular, it adds (is supposed to add) this line to load rvm as a shell function:
# Load RVM into a shell session as a function
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
I had a similar issue with the wrong ruby version running even after I changed the global default in rvm--ensuring this line was at the end of my .bash_profile fixed it. In any case, that line's supposed to be there for rvm to work properly.
You can make an .rvmrc file in the root directory of your application.
It runs whatever is inside on opening the root direct, so I think you can just copy this
PATH=$PATH:/usr/local/rvm/bin
and things should be good. You'll get a warning, but it's safe to ignore (or has been in my experience). I think you might be better off going with this, which I've found helpful to keep rubies/gemsets straight across applications.
#.rvmrc
rvm [ruby]#[gemset] #for example rvm 2.0.0-p247#my_gemset
Why gemsets/rubies get switched/reset in the first place, I really don't know and it is annoying, but this seems to fix it.

Depending on your setup it could not be loading for several reasons.
For instance, when you open a shell (depending on the OS distribution) bash files are read in various orders, although here is what the standard looks like: ( I believe Ubuntu is slightly different so you might want to check if thats your distro).
# for interactive login shells (when you login to a terminal)
/etc/profile
/home/<user>/.bash_profile
/home/<user>/.bash_login # if there is no .bash_profile
/home/<user>/.profile # if there is no .bash_login
# for interactive non-login shells (i.e. opening up a new tab)
/etc/bash.bashrc
/home/<user>/.bashrc
What happens when you directly source your .bashrc? Does it then find rvm? If so, then its just a matter of making sure your .bash_profile sources .bashrc aka:
# in .bash_profile
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
If this isn't the cause you could dive into the rvm documentation or switch to rbenv which IMHO is a much simpler solution.
RVM should handle this automatically but this code is wrong.
PATH=$PATH:/usr/local/rvm/bin
RVM's path should be first. Your bash is acting as you wish actually. It uses the 'system wide' ruby first because you tell your shell to do so. Change this to:
PATH=/usr/local/rvm/bin:$PATH
then source ~/.bashrc and it will work as you wish, calling rvm ruby when you login.

I am trying to create a permanent alias for my terminal. I put the alias in my ~/.profile, ~/.bashrc, and ~/.bash_profile files, previously empty. When I start a new terminal, bash does not recognize the alias, but if I source any of them, it does. Why are these not getting run when I open a terminal? I am on OSX.
Newer MacOS versions use zsh as the default shell for both Terminal and iTerm2. Run echo $SHELL to confirm if this is the case for you.
Zsh looks for a .zshrc file upon shell startup, so to continue using zsh while sourcing the contents of your bash profile, you can run the following:
echo "source ~/.bash_profile" >> ~/.zshrc
Open a new terminal window for the changes to take effect.
Two things need to happen here when using iTerm to get the loading of dotfiles to work.
First you should add the following to your .bash_profile
[[ -s ~/.bashrc ]] && source ~/.bashrc
Secondly you will need to ensure that in iTerm preferences your terminal is set to launch a login shell.
Hope this helps!
Using the default mac terminal, what worked for me was to add a command to run on start up to source my .bash_profile.
Preferences > Profile > Startup > Add command 'source ~/.bash_profile'
Mac terminal preferences window screenshot
Might be considered to be a bit hacky, but it does the trick.
Adding source ~/.profile to my .bash_profile worked for me.
As of High Sierra, both Terminal and iTerm want to load ~/.profile first. So I suggest you put one line in your .profile to make your Mac work like other Unixes:
source ~/.bash_profile
By editing this one file, you won't have to search through the menus of multiple apps to override Apple's bizarre behavior in each.
As of Catalina the default shell is now zsh. You can change it back to bash with chsh -s /bin/bash and that should load your .profile or .bash_profile
Why are your shell's initialization files not loading?
As with most things, It Depends ™
I recently experienced the same phenomenon and went through the following exercise to resolve it:
I use iTerm. iTerm runs a login shell by default. Verify in iTerm Preferences > General > Command > (*) Login Shell
Therefore, I know that ~/.bash_profile will always be called.
Knowing that, I put the following in my ~/.bash_profile file:
for file in ~/.{bashrc,bash_exports,bash_aliases,bash_functions}; do
[ -r "$file" ] && source "$file"
done
unset file
Notice that I use separate files for .bashrc, .bash_exports, etc. It keeps things separate and simple.
Note also that /etc/profile is loaded first, but since I have never used that system wide init file, I knew that that was not my problem. For details check out $ man bash
So, I started with my ~/.bash_profile file.
I found that when I installed Canopy Express that it's installer replaced the contents of my ~/.bash_profile file with the following content:
# Added by Canopy installer on 2017-04-19
# VIRTUAL_ENV_DISABLE_PROMPT can be set to '' to make the bash prompt show that Canopy is active, otherwise 1
alias activate_canopy="source '/Users/lex/dev/python/User/bin/activate'"
# VIRTUAL_ENV_DISABLE_PROMPT=1 source '/Users/lex/dev/python/User/bin/activate'
p.s. Canopy is an excellent, free python IDE, that I highly recommend.
Fortunately, I backup my ~/.bash* files so restoring that was easy and quickly fixed my issue.
My advice would be to understand the order of calls to your initialization files and start with the first one and work your way through them until you find the problem.
Oh, and you may want to verify which shell you are using (I use bash):
~ $ echo $SHELL
/usr/local/bin/bash
I am guessing you may use another shell, such as bash, tcsh, sh, zsh etc.
Put source .bash_profile into your appropriate 'bashrc' file will make the auto loading recovered, i.e.
.login for tcsh, .bash_profile for bash, .zshrc for zsh
My issue was solved by unchecking Preferences > General > tmux >
Use "tmux" profile rather than profile of the connecting session
Most likely, you need to create the files yourself as they appear not to exist by default. You should give them execute permission to make them run.
~ % sudo chmod 700 ~/.bash_profile
Also, you should check the ownership of the files. They should belong to current user rather than root. Otherwise, you will get permission denied error.
~ % ls -a -l
~ % sudo chown <user_name> ~/.bash_profile
Finally, please note that bash looks in your home directory for .bash_profile, .bash_login, and .profile in order. Bash will stop looking if the first is found.
This means if you have both .bash_profile and .profile files, the .profile will not run.
For more information
Hope this would help you.
Little late to the party but it seems that the file .zprofile is the equivalent to that of .bash_profile when loading zsh. I used this instead to execute a few commands on startup. Of course this only valid for a specific iTerm setup with zsh.

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
I've done a lot of searching and there seem to be similar issues, but none that have helped me solve this problem. I'm fairly new to Ruby, Rails, and -ix systems so that doesn't help much, either. :(
I was able to get RVM up and running along with the latest versions (1.9.3-p125 of Ruby and 3.2 of Rails). However, when I exit terminal and come back in the system defaults are being used. When I tried to change versions I received a "command not found". I then tried just typing "rvm" and got:
-bash: rvm: command not found
I followed some other tutorial advice and modified my ~/.bashrc file to look like this:
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"' >> ~/.bashrc
but I'm still getting the exact same "command not found" even after exiting Terminal.
Any thoughts on how to get RVM working properly? Everyone says use it, but it sure isn't simple...
Thanks a lot!
Greg
I followed some other tutorial advice and modified my ~/.bashrc file
Usually I modify .profile file on Mac OS X, and .bashrc on Linux. Try to modify .profile
Please check How to fix Terminal not loading ~/.bashrc on OS X Lion to know why Terminal doesn't load .bashrc file.
If you modify your .bashrc you either need to immediately source it or create a new shell to see the changes take effect.
The standard rvm procedure is to source the rvm script that is created. The installation documentation covers most use cases.
If your rvm command is missing, it's possible that your .bashrc is not working as you expect. Is your PATH being modified as you've requested? If not you might have another issue.
RVM is installed on my machine (running Mac OSX 10.6.8), correctly and it runs fine. The odd thing is that to run it, I have to use source ~/.rvm/scripts/rvm for every new session. I tried making a symlink from it to /opt/local/bin/rvm, but when it runs it does nothing. I also tried creating a symlink from ~/.rvm/bin/rvm to /opt/local/bin/rvm, and when I run rvm in the Terminal it displays the help page, as expected. But when I try rvm use some_ruby_version it always displays "RVM is not a function, selecting rubies with 'rvm use ...' will not work.". How can I fix this?
My goal is to get it to the the point that I don't have to type the source command every session, and for some reason ~/.profile does not execute.
You have to source the RVM script into the current session because it makes changes to the shell environment - and it is absolutely impossible for that to be done from a child process. Your efforts at running RVM as an external command cannot succeed.
To actually fix this you have two choices:
Configure your terminal emulator to start a login shell, rather than a non-login shell, so that your .profile is loaded.
Modify .bashrc to source RVM instead, which works for non-login shells as well.
To do the second you can just add to ~/.bashrc:
if test -f ~/.rvm/scripts/rvm; then
[ "$(type -t rvm)" = "function" ] || source ~/.rvm/scripts/rvm
fi
If you are using zsh as shell instead bash, you have to:
1.
vi ~/.zshrc
2.
Like Matt said, add:
if test -f ~/.rvm/scripts/rvm; then
[ "$(type -t rvm)" = "function" ] || source ~/.rvm/scripts/rvm
fi
3. Restart Terminall
4. Done!
rvm use 1.9.3
Wil work
I didn't understand what ~/.profile does correctly; I needed to change ~/.bash_profile instead. Problem solved!
Well, with mountain lion (10.8.3) what worked for me was editing /etc/profile
and adding the line mentioned before at the bottom of the file:
if test -f ~/.rvm/scripts/rvm; then
[ "$(type -t rvm)" = "function" ] || source ~/.rvm/scripts/rvm
fi
I had the same issue. I found the .profile file was not getting updated, so i added the same command that was added into .bash_profile:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
I don't know if this is the right way, but it worked...
You shouldn't need to edit anything as others suggest. Just go into your terminal's settings and select the "Run command as login shell". This will cause .profile to run on the next terminal instance. Reopen your terminal and you should be able to use rvm use 1.9.3 (or whatever version you installed).
More info found on rvm.io (which is also a great place for answers)
https://rvm.io/integration/gnome-terminal
You have to make some settings.
Open terminal and run this command.
source ~/.rvm/scripts/rvm
and then go to edit > Title and command and check Run command as login shell
and you are done. Now you don't need to specify source everytime.
What was screwing me up was assuming my path was correct since I was using one I can run manually.
Apparently there are different executables or scripts that can be used and are located in different places.
I thought that the path Mina should use was this:
/usr/local/rvm/bin/rvm
When in reality it was this:
/usr/local/rvm/scripts/rvm
I had this issue when I became root. I tried many of the solutions above. What finally worked was exiting from root and being a regular user. Which is what I needed anyway.
None of these solutions seemed to redeem my problem which was on Ubuntu 12.04 LTS.
What I did is the following:
rvm get stable --auto-dotfiles as outlined in the RVM documentation here
Added source ~/.profile as the first line of: ~/.bash_profile
I will not all of these steps were documented as errors from the RVM command line:
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.
and
WARNING: You have '~/.profile' file, you might want to load it,
to do that add the following line to '/home/user_name/.bash_profile':
source ~/.profile
I think I screwed up my development environment the other day and I can't figure out how to get RVM working again.
I cleaned up my startup files for my shell and consolidated my .profile, .bash_profile, .bash_login, and .bashrc files into a single .bash_profile in my user directory.
Ever since I did this, my RVM environment has been screwed up. Now, when I do a which rails and which ruby, my system is now referencing my /usr/local/bin directory instead of my ~/.rvm/bin like it used to.
Here are the first two lines of my .bash_profile config:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/git/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin:$PATH"
I'm not a UNIX guru and I fear that I'm missing a certain variable name in my "$PATH" declaration. Any help would be greatly appreciated.
Try to add the RVM line at the end of your .profile and ensure that there are no return statement in it.
See the RVM installation documentation.
Especially :
Ensure that RVM is sourced after any path settings as RVM and manipulates the path. If you don't do this, RVM may not work as expected.
