ruby – 在[](Gem :: LoadError)中找不到heroku(> = 0)

微克.我刚刚从 Windows 7安装迁移到Lion系统.我正在尝试自学 Ruby on Rails,虽然我喜欢这种语言,但环境却让人感到脆弱和神秘.我使用相同的命令在两个系统上安装heroku,但System X系统对安装不满意.

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？

如何让heroku运行起来？什么会阻止下一个宝石丢失？

$sudo gem install heroku
...

$heroku -v

解决方法

这可能很有用.它适用于我的环境.

rvmsudo gem install heroku
