ERROR: Unrecognized command line argument: 'pkg' ( see: 'rvm usage' )

Question

I am trying to run

rvm pkg install zlib

and I get the following message

ERROR: Unrecognized command line argument: 'pkg' ( see: 'rvm usage' )

I installed rvm by running:

sudo apt-get install ruby-rvm

I have searched online but I have only found a similar error stating that package

has changed to pkg, but in this case I am using pkg. Any ideas? I am using Ubuntu 11.10 x64

Thank you in advance

Answer 1

It seems I didn't install rvm as I should.

First uninstall ruby-rvm by running:

$ sudo apt-get --purge remove ruby-rvm 

Then install rvm by running:

bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )
