Recipes that alter PATH

Hello,

I have a recipe that installs rvm and Ruby Enterprise Edition via rvm. Once
that recipe runs, I have subsequent recipes that run and install gems. The
problem is that they install the gems in system Ruby.

For rvm to work, I need to source a shell script (which I do in
/etc/profile.d/rvm.sh). The problem is that subsequent calls to Chef
resources like “execute”, “gem_package” or “script” don’t
run /etc/profile.d/rvm.sh before executing. How can I remedy that?

Thanks for the help.

This is commonly solved with the 'reboot' cookbook, to restart the Chef run
mid to inherit the new environment.

Regards,

AJ

The trick is to run the RVM command, then evaluate the environment in
the sub-shell and set the current running environment to match.

Pretty nifty trick! Unfortunately it doesn't work for me. Every subsequent
use of the "bash" resource errors with "No such file or directory - bash
/tmp/chef-script.1990.0". I printed out my ENV["PATH"] after your
ruby_block trick and it looks correct.

I'm using Chef 0.7.16.

Does the reboot cookbook require a certain version of Chef?

Thanks for the help.
