RVM installed by Ruby not working?

RVM requires a minor addition to your ~/.bashrc or ~/.bash_profile to initialize it when you log-in. It is specified in the installation docs in the Post Install section. Did you do that?

Per your rvm info output, it looks like you haven't completed your installation. All the entries in the output should have corresponding values. So, I suspect you haven't added:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"  # This loads RVM into a shell session.

to your ~/.bashrc or ~/.bash_profile and then started a new session.

If you are doing a "Multi-User" installation then you'll need to do a lot more. Have you modified /etc/profile, or, if you are using Bash as your shell, have you modified /etc/bash.bashrc to include:

# 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

and started a new shell?

Personally I don't like the multi-user install as much as the single-user install, and don't recommend it but your mileage might vary.

As a FYI: In a discussion with the RVM maintainers on IRC last year, they told me they do not recommend the system-wide installation, and instead recommend the local "single-user" installation, even for servers.

I installed Ruby on Rails on a Ubuntu 11.10 VM, using "HOW TO INSTALL RUBY ON RAILS IN UBUNTU 11.10".

After installing it, I was running into the same issue. The only thing that seems to be missing from the tutorial in my opinion, is the following command:

rvm --default use 1.9.2

Although Ruby is properly installed, RVM seems to redefine in each session Ruby is to be used. The problem was that the default Ruby pointed to the "system ruby", and, in my case, this one pointed to nowhere and made the call rvm info return a result similar to the initial post.

To solve this issue, one of the follwings commands must be used:

rvm  --default use 1.9.x

or (valid only for the current session)

rvm use 1.9.x

Before I could start the server, I also came across "ExecJS and could not find a JavaScript runtime". As proposed in several answers, I solved it by adding the following lines to the Gemfile.

gem 'execjs'

gem 'therubyracer'

and running bundle install afterwards.

I had similar problem (using Ubuntu 13.10) to solve it

$ source .rvm/scripts/rvm 

and for long term

$ echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc

$ ruby -v


The program 'ruby' can be found in the following packages:
 * ruby1.8
 * ruby1.9.1
Try: sudo apt-get install <selected package>

$ source .rvm/scripts/rvm

$ ruby -v

ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-linux]

I faced the same issue. You might need to login first:

/bin/bash --login

Here is how to fix undetected Rubies inside RVM.

First, I did a sanity check to make sure that very thing looks great, then ran

rvm use ruby --default

which did the job. It comes down to this command:

-SVE1411EGXB:~/code$ cd app1/
  -SVE1411EGXB:~/code/app1$ rails s
The program 'rails' can be found in the following packages:
 * ruby-railties-3.2
 * ruby-railties-4.0
Try: sudo apt-get install <selected package>
