Heroku Gem安装后无法正常工作

Question

我想在Ubuntu 9.10上运行heroku

我打字了

sudo gem install heroku

一切正常,但是当我去跑步时:

heroku list

我明白了

heroku:命令未找到

Answer 1

运行gem enviroment并查看EXECUTABLE DIRECTORY的位置并将其添加到PATH中

就我而言:

$ gem environment
RubyGems Environment:
  - RUBYGEMS VERSION: 1.3.5
  - RUBY VERSION: 1.8.7 (2009-06-12 patchlevel 174) [i486-linux]
  - INSTALLATION DIRECTORY: /var/lib/gems/1.8
  - RUBY EXECUTABLE: /usr/bin/ruby1.8

  - GEM PATHS:

     - /home/user/.gem/ruby/1.8

  - REMOTE SOURCES:

$ export PATH=$PATH:/var/lib/gems/1.8/bin

或者添加到〜/ .bashrc
