use and run_command don't work in rails console or rake

[hbarrington]

running the following works in IRB but not rails console or rake
env = RVM::Environment.new('system')
env.shell_wrapper.run_command("cd ~/opscode/FTW && knife rackspace server list")

output shows:

my first guess is it has to do with bundler... i'll update if i find anything

[mpapis]

does it work with other rubies ? I do not think system was ever supported in this scenario.

[hbarrington]

I tried installing 1.8.7 and using that instead of system. seems to be the same error. Is there something I can run to get an idea of environment variables and see what might be the issue? Source code for the RVM gem doesn't suggest anything at first or second glance

[mpapis]

@hbarrington here is part of the documentation i found https://github.com/wayneeseguin/rvm-gem/blob/master/lib/rvm.rb ... what I understood the run will be automatically used on current and you can change only gemsets with RVM.gemset_use! '1.9.3@project'

if you would like to have a selectable environments so you could invoke commands in they scope - this would require changes, please open new ticket for it.

[hbarrington]

used:
RVM.gemset_use! '1.8.7@knife'
env = RVM.current
puts(env.shell_wrapper.run_command("cd /home/hunter/opscode/FTW && knife rackspace server list"))

received the same error. Not sure exactly what you mean about "selectable environments so you could invoke commands". I thought that was the point of rvm. Am I missing something? A little documentation might help but I don't mind reading source

[mpapis]

you can not change the loaded ruby version and you try to switch to 1.8.7 from 1.9.2 - this will not work, what you need is a possibility to select any ruby and allow running commands in context of this ruby, please open a new ticket for it

[hbarrington]

@mpapis thanks for spelling it out for me... I wasnt making the connection. Thanks
