rvm notes
Error:
/usr/local/bin/rvm: line 73: /home/cody/.rvm/scripts/rvm: No such file or directory
flashes in multiple lines and doesn't stop till I hit ctrl+C..
I am running Ubuntu 8.04 and currently I am running ruby 1.9.2..
Sorry, if I am missing out any necessary information. Thanks in advance.
Ack, I didn't mean to post this as a comment on the question. Anyway, if I had to guess, I'd say you installed rvm using sudo or as root. If that is the case, remove it and reinstall without sudo:
sudo rm -rf $HOME/.rvm $HOME/.rvmrc /etc/rvmrc /etc/profile.d/rvm.sh \
/usr/local/rvm /usr/local/bin/rvm
sudo /usr/sbin/groupdel rvm # this might fail, it's not that important
Open new terminal window/tab and make sure rvm is removed:
env | grep rvm
The output should be empty, sometimes it's needed to relogin, after it's empty you can continue:
curl -sSL https://get.rvm.io | bash -s stable
It works perfectly fine installed for the local user.
Ok, for anyone who tried to install RVM using sudo and is now pulling
their hair out trying to get it to install in $HOME/.rvm, here's what
did it for me:
When you installed RVM using sudo, it created a file /etc/rvmrc, which contains the following:
umask g+w
export rvm_path="/usr/local/rvm"
This makes all future attempts at installation (even when not run as sudo)
install into /usr/local/rvm, which is NOT what you want for a single
user installation. So remove /etc/rvmrc and then you can run
bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
and it will install properly into $HOME/.rvm
DId you add this line to your ~/.bashrc?
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
I have executed the commands as prescribed in the instructions at the rvm website.
WHICH commands? There are several pages containing instructions to install RVM depending on whether you want a single-user "sandbox" or are installing system-wide for a multi-user system as the administrator.
Because you have RVM in /usr/local, I think you tried to do a system-wide install but didn't get it right. For 99% of us, that is the wrong installation method, and instead you should use the single-user installation, which is simple and puts everything in ~/.rvm.
Either way, be sure to read the entire instructions. And, if doing a single-user install, finish the install with the "Post Install" modifications to ~/.bashrc or ~/.bash_profile for a single-user, then start a new terminal session.
When using the single-user install NEVER use sudo to install gems to a RVM-managed Ruby, even though the instructions for a gem might say to.
Look at the section "Troubleshooting your install" here. Since you are on Ubuntu, you probably need to make further mods to you .bashrc
in .bashrc have you changed the
[ -z "$PS1" ] && return
to
if [[ -n "$PS1" ]]; then
and added this to the end of the file:
fi
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
I just had a similar problem.
It turned out that many files in ~/.rvm/scripts/ and ~/.rvm/src/rvm/scripts/ which obviously should be executable did not have execute permissions. Running a script on both directories to set all files to executable solved that immediate problem.
I have got same problem after installation. Then I restarted terminal and it started working poperly.

I am trying to have RVM and ruby installed in an Ubuntu 12 virtual machine without human interaction apart from the password prompts.
I created a shell script to do this that works pretty fine until I need to use RVM itself.
I am using multi-user installation.
#!/bin/bash -l
mainUser=`whoami`
echo "Installing as '${mainUser}'"
echo "Installing git..."
sudo -S apt-get install --yes curl git-core
echo "Installing RVM..."
\curl -L https://get.rvm.io | sudo bash -s stable
echo "Adding ${mainuser} to RVM group..."
sudo adduser $mainUser rvm
newgrp rvm
From here things get weird.. I need to load dvm as a source. I want both my script to have this source and my user's bash_profile / bashrc. Anyway.. I know how to do it manually, but I can't have this done from the script. This is the last code I tried:
. "/usr/local/rvm/bin/rvm"
rvm use ruby-head
rubyVersion=`rvm list | awk '/ruby-head/{print x;print};{x=$0}' | sed -n '/ruby-head/{g;1!p;};h' | awk -F ' ' '{print $1}'`
rubyTest=${rubyVersion}#test
rvm use $rubyTest --create --default
The error I get is this:
test.sh: 7: /usr/local/rvm/bin/rvm: Syntax error: "(" unexpected (expecting "fi")
If I simply try to use the full path, like this:
rvm=/usr/local/rvm/bin/rvm
$rvm use ruby-head
rubyVersion=`$rvm list | awk '/ruby-head/{print x;print};{x=$0}' | sed -n '/ruby-head/{g;1!p;};h' | awk -F ' ' '{print $1}'`
rubyTest =${rubyVersion}#test
$rvm use $rubyTest --create --default
I get this error instead:
RVM is not a function, selecting rubies with 'rvm use ...' will not work.
I am clueless. Why can't I use /usr/local/rvm/bin/rvm?
Is there a way to execute source /etc/profile.d/rvm.sh for this user from the script?
I am not so good at shell script and Linux, so I appreciate any references and examples you could give.
Thanks!
UPDATE
I also tried:
source "/usr/local/rvm/scripts/rvm"
... and all it's variants. Same error: "RVM is not a function".
rvm is actually implemented as a shell function rather than an executable, which is why you can't just call /usr/local/rvm/bin/rvm itself.
Quoting you, "Is there a way to execute source /etc/profile.d/rvm.sh for this user from the script?"
Have you tried doing that? I had a somewhat similar install once where it didn't work properly from crontab (they have instructions on the site for that scenario, but we couldn't make them work), and I had to do almost exactly that -- source part of the profile.d for rvm.
RVM is not a function, selecting rubies with 'rvm use ...' will not work.
Above error is generated when rvm is not running and hence your terminal is not able to recognize it, as it tries to run it as a system command.
You may want to try this to run rvm through your shell script before calling rvm methods:
source ~/.rvm/scripts/rvm
I found out what is causing the issue.
I realised before that I would get errors in the lines with conditions in the script files, so I came across this page:
https://superuser.com/questions/552016/bash-script-not-found
As it happens, I was executing the script with the following command:
sh script.sh
Which means I was getting Dash instead of Bash.
To fix the issue I changed my code to have this:
PATH=$PATH:/usr/local/rvm/bin # Add RVM to PATH for scripting
[[ -s "/usr/local/rvm/scripts/rvm" ]] && . "/usr/local/rvm/scripts/rvm" # Load RVM function
And then I executed like this:
bash script.sh
And voilà... RVM works again!
I'm new to Ruby and just installed it following the instructions on this website.
I'm not sure why, but now whenever I open terminal, I get the following error message:
-bash: HOME/.rvm/scripts/rvm: No such file or directory
Is there something I'm missing? As far as I can tell, Ruby is installed correctly and is running fine.
It looks like you put HOME in your .bash_profile instead of $HOME. You should also verify that your .rvm directory exists in your home directory. You could also check the value of $HOME by running echo $HOME in a shell, and it should return something like /home/yourname.
Note: You could change "$HOME" to "~".
This maybe solve your problem:
Before you install RVM, you can input this in your terminal to check server key:
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
Then you can input the following command to install rvm
curl -L https://get.rvm.io | bash -s stable
Just have a try~
You must source the rvm scripts so that they are available to your terminal session
source /usr/local/rvm/scripts/rvm
source ~/.rvm/scripts/rvm
You may want to add it to your .bash_profile or .bashrc file so that they are executed every time you load a terminal window like so:
$ echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"' >> .bashrc
RVM is not working over SSH.
At the command-line:
leifg#host:~$ which ruby
/usr/local/rvm/rubies/ruby-1.9.2-p290/bin/ruby
Connected over SSH:
local:~$ ssh leifg#server 'which ruby'
/usr/bin/ruby
I'm using Ubuntu 11.04.
How do I get SSH to use the same Ruby as it is on the system?
I already verified some prequisites:
Ruby was already installed using apt-get install ruby. Does that make any difference?
sshd_config has the option "PermitUserEnvironment yes", and I restarted the daemon.
The .bashrc on the server contains these lines, but I see the same behavior when I remove them:
if [ -s "$HOME/.rvm/scripts/rvm" ] ; then
. "$HOME/.rvm/scripts/rvm"
elif [ -s "/usr/local/rvm/scripts/rvm" ] ; then
. "/usr/local/rvm/scripts/rvm"
fi
Actually, your ~/.bashrc will be executed. The problem is usually that one adds the
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
... snippet at the bottom of the file. However, the default .bashrc on ubuntu systems includes the following near the top
# If not running interactively, don't do anything
[ -z "$PS1" ] && return
That call will stop executing the rest of the script and will therefore not set the proper paths. So you can either put the rvm call at the top of the file or remove the return call.
From the ssh man page:
If command is specified, it is executed on the remote host instead of
a login shell.
This should mean that your .bashrc won't get sourced, so RVM doesn't get set up.
Solution
This did the trick in the end:
ssh <host> bash --login -c <command>
Start bash as a login shell through SSH and then start the RVM installed Ruby via SSH's -c option.
Actually there's totally another, more safe and lightweight option.
You add "PermitUserEnvironment yes" somewhere to your sshd_config in /etc/(open)ssh
Now you are allowed to specify user environment in /home/user/.ssh/environment. So what do you put there ?
Just something like :
user# env | grep rvm > ~/.ssh/environment
so it looks like below :
user#app3:~$ cat ~/.ssh/environment
rvm_bin_path=/usr/local/rvm/bin
GEM_HOME=/usr/local/rvm/gems/ree-1.8.7-2012.02
IRBRC=/usr/local/rvm/rubies/ree-1.8.7-2012.02/.irbrc
MY_RUBY_HOME=/usr/local/rvm/rubies/ree-1.8.7-2012.02
rvm_path=/usr/local/rvm
rvm_prefix=/usr/local
PATH=/usr/local/rvm/gems/ree-1.8.7-2012.02/bin:/usr/local/rvm/gems/ree-1.8.7-2012.02#global/bin:/usr/local/rvm/rubies/ree-1.8.7-2012.02/bin:/usr/local/rvm/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
rvm_version=1.14.5 (stable)
GEM_PATH=/usr/local/rvm/gems/ree-1.8.7-2012.02:/usr/local/rvm/gems/ree-1.8.7-2012.02#global
Note: this also works work user-install RVM (not only for the system wide)
Now your are able to use ruby in ssh non interactive sessions :
ssh user#app3 'ruby --version'
ruby 1.8.7 (2012-02-08 MBARI 8/0x6770 on patchlevel 358) [x86_64-linux], MBARI 0x6770, Ruby Enterprise Edition 2012.02
Voila!
“rvm” has two invocation bugs: the default installation drops the file /etc/profile.d/rvm.sh and believes any bash trick is now globally available. – This assumption is wrong.
Files in /etc/profile.d/ are “sourced” on login, but maybe not from bash, maybe not even from a shell. So the cd hook it installs is not there after the shell which runs these files exits. Actually, because of the buggy way “rvm” installs this hook, it is already gone once you run naked bash in a login-shell!
I don’t know if “rvm” supports an explicit invocation for virtual environments, without relying on cding into some directory (that I consider the second bug).
There is one sane workaround:
Make your shell source /etc/profile.d/rvm.sh from e.g. ~/.bashrc. .bashrc is executed from any non-login bash, and login-bash is usually setup to source .bashrc from those login-shell files like ~/.profile
For your ssh problem: should a proper ssh-shell not be login-shell anyway?
I've just added at the top of ~/.bashrc (for git user) this string:
[[ -s "/usr/local/rvm/scripts/rvm" ]] && source "/usr/local/rvm/scripts/rvm"
Mentioned solutions work certainly fine, but mine was to run
source /usr/local/rvm/environments/<ruby version>#<gemset version>
at the start of the remote ssh call. Something like:
ssh -l <remote username> <server ip> "source /usr/local/rvm/environments/<ruby version>#<gemset version> ; <rest of the remote script>"
(if using Capistrano) Don't use rvm1/capistrano3 or rvm/capistrano; don't set :pty.
Change ~/.rvmrc for the runner user, on the server, to this — note that it has to come before the line where it kills itself when not running interactively:
# get rvm for non-interactive shells (eg capistrano) too
source /etc/profile.d/rvm.sh
export BASH_ENV=$HOME/.bashrc
export rvm_is_not_a_shell_function=0
# If not running interactively, don't do anything
[ -z "$PS1" ] && return
I had the same problem. I realized, that I accidentally installed RVM for multiple users, too. After deleting the directory /usr/local/rvm and edit ~/.bashrc like zoonmix suggested, the problem was solved.
Make sure that on the server you have done something like rvm --default 1.9.2 to set RVM's Ruby to be the default. Otherwise, it will always use the default system Ruby.
zoomix's is the best solution. But when you change with "ruby rvm use system" in terminal or what else you get an error :
Warning! PATH is not properly set up, is not at first place.... To solve that put the snippet just before the return instead of at the top of the .bashrc file (Debian Jessie here)

My RVM system-wide installation scripts are broken, both in the form of Linode StackScripts and Chef-solo Recipes.
Per the instructions on the RVM website, my scripts execute the following commands as root to install RVM on a system-wide basis:
echo "Installing RVM system-wide" >> $logfile
bash < <( curl -L http://bit.ly/rvm-install-system-wide )
cat >> /etc/profile <<'EOF'
# Load RVM if it is installed,
# first try to load user install
# then try to load root install, if user install is not there.
if [ -s "$HOME/.rvm/scripts/rvm" ] ; then
. "$HOME/.rvm/scripts/rvm"
elif [ -s "/usr/local/rvm/scripts/rvm" ] ; then
. "/usr/local/rvm/scripts/rvm"
fi
EOF
source /etc/profile
The key piece above is the url http://bit.ly/rvm-install-system-wide. As of today, 3/24/2011, this url no longer in service. It results in a GitHub 404 error.
The following url on the RVM website used to contain the instructions for the system-wide install: http://rvm.beginrescueend.com/deployment/system-wide/. However, that url now redirects to the RVM homepage.
In the interests of getting RVM system-wide installation scripts to work again, what are the new instructions?
Here is my fix to install the last working version before he major change:
bash <( curl -L https://github.com/wayneeseguin/rvm/raw/1.3.0/contrib/install-system-wide ) --version '1.3.0'
This is working for me now in production. Good luck!
UPDATE
Also, if you are using the chef cookbook from https://github.com/fnichol/chef-rvm or something similar, you can use the following options:
:rvm => {
:system_installer_url => "https://github.com/wayneeseguin/rvm/raw/1.3.0/contrib/install-system-wide",
:version => "1.3.0"
}
Just received the following answer from the lead developer, wayneeseguin, on #rvm:
[12:53] "the author" merged it into the ain installer
[12:53] so you should be doing
bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
# http://rvm.beginrescueend.com/rvm/install/
[12:53] the code has just changed and the documentation hasn't caught up
[12:53] for both root and user installs
It is true that RVM 1.5.1 will successfully install into /usr/local/bin just by installing as root. However, for some reason, all the existing Chef and Puppet provisioning scripts that are in use today do not appear to survive this version bump. This is unfortunate, as Wayne E. Seguin has made clear that RVM below version 1.5.0 will not be supported.
That said, we need our systems to work today. In order to continue to use RVM 1.3.0, which the existing scripts support, you need to replace the following line:
bash < <( curl -L http://bit.ly/rvm-install-system-wide )
With the following line (found by phlipper):
bash -c "bash <( curl -L https://github.com/wayneeseguin/rvm/raw/1.3.0/contrib/install-system-wide ) --version '1.3.0'"
I'm having trouble getting the Ruby Version Manager rvm to source from my Ubuntu 10.04 .profile. The code:
[[ -s "$HOME/.rvm/scripts/rvm" ] && . "$HOME/.rvm/scripts/rvm"
...never does what I expect it to (i.e. give me the rvm program when I open a new shell or start a new session); but if I execute
source .profile
in a new shell after logging in, it works! Why will it work when I manually source it, but not automatically at login?
It would appear that Ubuntu handles it's logon scripts differently than most other linux distros
http://ubuntuforums.org/showpost.php?p=9127226&postcount=6
The above post has hints that GDM logins in Ubuntu don't process .bash_profile or .profile the way most other linux distros do. I have had to put the line loading RVM in the ~/.bashrc and that has not caused any problems yet.
Sourcing $HOME/.rvm assumes you have installed RVM a single user, specially, the user whose home directory is $HOME. Likely, on your Ubuntu system, RVM has been installed system wide, and thus you must source the RVM scripts as such:
In your .bashrc file add:
\# Set rvm path
[[ -s "/usr/local/rvm/scripts/rvm" ]] && source "/usr/local/rvm/scripts/rvm"
before this line; this line will exit and not execute anything past it, which is fine for interactive logins, bit would be a problem is you are using non-interactive SSH logins for automation purposes.
\# If not running interactively, don't do anything
[ -z "$PS1" ] && return
The RVM installation page has a series of things to check to test the initialization of RVM. Read the "Troubleshooting your Install" section at the end of the RVM installation page.
Also, here's a description of how Bash reads its startup files which can help with this sort of problem.
I had a problem with Atom editor not picking up RVM environment and thus not finding rubocop command on Ubuntu 16.04. But the problem was not there when I started Atom from gnome terminal. What I've found was that RVM script ~/.rvm/scripts/rvm that you're supposed to be loading in your .profile has these lines at the beginning:
if
builtin test -n "${BASH_VERSION:-}" -o -n "${ZSH_VERSION:-}" -o -n "${KSH_VERSION:-}"
then
...
else
return 0
fi
Strangely, when executed at login, I've found $BASH_VERSION to be empty (while in gnome terminal it's sth like 4.3.46(1)-release), so the script would do early return leaving RVM not loaded properly. I tried to set BASH_VERSION to whatever and it worked fine.
Here is the complete code from my .profile that loads RVM:
local rvm_home="${HOME}/.rvm"
export PATH="$PATH:${rvm_home}/bin"
if [ -z "$BASH_VERSION" ]; then
export BASH_VERSION=4
fi
source "${rvm_home}/scripts/rvm"
