RVM: how can I dynamically export gem executable directory in my path?

Question

I installed rvm as root to setup an Ubuntu LTS 8.04 as a web hosting server for my rails apps.

rvm is installed in:

/usr/local/rvm

Everything works fine, gems installation included and users are able to use ruby and gem commands.

sudo gem install rails

My problem is that the gems EXECUTABLE DIRECTORY is not included in my PATH and thus I cannot use rails command.

Is there a way to dynamycally include gems executable directory in my PATH?

Can it be done directly through rvm?

Answer 1

I suspect you don't have RVM setup correctly if it's not in your path.

First, If you run:

type rvm | head -1

and it returns anything other "rvm is a function" then you are not loading it correctly in your profiles.

Second, you may want to include global definitions for the users profiles.

In your users' .bashrc or equivalent

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi

And then in your /etc/bashrc, add your executable path.

Probably your PATH was overwritten somewhere on the way, you can put that on end of your ~/.bashrc file:

export PATH=/usr/bin:$(echo $GEM_PATH | sed 's/:/\/bin:/g')/bin:$MY_RUBY_HOME/bin:$PATH

it is not pretty but should work
