I just started to study Ruby on Rails to use heroku.
I installed Ruby 1.9.3p327 and Rails 3.2.8 by using homebrew. (Mac OS X)
After install Ruby & Rails, When I type “gem install heroku”, below
gem install heroku
ERROR: Could not find a valid gem ‘heroku’ (>= 0) in any repository
ERROR: Possible alternatives: heroku
In some Q&A site, it said it should be PROXY server problem, but I don’t
Another Q&A site said Firewall might be problem, but it doesn’t work
even if I disable firewall.
Could anyone give me advice to solve this issue?
I also tried to down load heroku gem directly from
but everytime I failed with the message “ Bad Gateway”
