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?
When I run:
gem install susy --version 0.9 -V
I see that gem is going to rubygems.org for the gem in question.
However when I look for the susy gem on that server, all I find is version 1.0.1.
In your Gemfile, you could try to specify the source of the gem from a git repo as they do in this question.
Normally, you'd put all of your gems you want to use in a Gemfile and then run bundle install from the directory that contains the Gemfile.
The 0.9 version of the Susy gem was called compass-susy-plugin. What you want is:
gem install compass-susy-plugin
