So, I started installing Capistrano yesterday using:
gems install capistrano
Annoyingly, the net-ssh dependency failed with the hideous error message:
ERROR: While executing gem … (Zlib::BufError) buffer error
This seems to only happen on windows - and there doesn't seem to be any documentation on how to fix this.
Thankfully, you can fix this problem by upgrading your RubyGems install using
gem update --system
I then installed Capistrano with no probs!
