From: Kunio Takamoto Date: 2012-11-18T09:14:30+09:00 Subject: Cannot install heroku gem Hi, 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 error happened, -------------------------------------- > 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 use it. 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? Regards, KT ---- I also tried to down load heroku gem directly from "http://rubygems.org/" but everytime I failed with the message "[502] Bad Gateway" -- Posted via http://www.ruby-forum.com/.
