I am trying to install ruby 2.0 on my ubuntu box and I keep getting the following:
SERVER_USER@SERVER_NAME:/var/www/FOLDER_NAME$ rvm get stable && rvm install ruby-2.0.0
ERROR: Unknown ruby interpreter version: '2.0.0'

curl: (3) <url> malformed
ERROR: There was an error, please check /usr/share/ruby-rvm/log/ruby-2.0.0-p247/*.log. Next we'll try to fetch via http.
Trying http:// URL instead.

Halting the installation.
ERROR: There has been an error fetching the ruby interpreter. Halting the installation.
The log it mentions also doesn't exist. Also if it helps at all when I run:
rvm requirements
I get back
ERROR: Unrecognized command line argument: 'requirements' ( see: 'rvm usage' )
which i haven't seen before
回答1:
Turns out my rvm was busted because i had used apt-get install ruby-rvm instead of the curl directly from rvm.io, so reinstalling rvm did the trick.
