在[]（Gem :: LoadError）中找不到heroku（> = 0） [英] Could not find heroku (>= 0) amongst [] (Gem::LoadError)

问题描述

Ug的。我刚刚从Windows 7安装迁移到Lion系统。我试图自学Ruby on Rails，虽然我喜欢这种语言，但是这个环境感觉脆弱而神秘。我使用了相同的命令在两个系统上安装heroku，但System X系统对安装并不满意。

在System X上，我使用了rvm，这可能是我的问题。

什么控制Gems的安装位置？

我如何获得并运行heroku？

  $ sudo gem install heroku 
 ... 
 
 $ heroku -v

解决方案

这可能很有用。它适用于我的环境。

  rvmsudo gem install heroku 
  

请参阅：找不到在（]（Gem :: LoadError）之间的轨道（> = 0）

Ug. I just moved from a Windows 7 installation to a Lion system. I'm attempting to teach myself Ruby on Rails, and whilst I like the language, the environment feels fragile and mysterious. I used the same command to install heroku on both systems, but the System X system is not happy with the install.

On System X I used rvm, which might be my problem.

What controls where Gems are installed?

How can I get heroku up and running? And what will prevent the next gem from getting lost?

$ sudo gem install heroku
...

$ heroku -v

解决方案

This might be useful. It worked on my environment.

rvmsudo gem install heroku
