I need to install susy with gem. When I type
sudo gem install susy --version 0.9
It would result an error message:
ERROR: Could not find a valid gem 'susy' (= 0.9) in any repository
However I have checked the source at github and the 0.9 tag does exist.
How can this happen? How to force rubygem to download those specific version instead of the latest version?
The 0.9 version of the Susy gem was called compass-susy-plugin
. What you want is:
gem install compass-susy-plugin
