Question

非常乐意帮助我们学习如何处理所有这些宝石，并在安装“gem install x”时遇到问题。我到处都读到使用'sudo'不是最好的做法。

-facts -

gem install cucumber返回'You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.'

哪个宝石返回/usr/bin/gem

gem env返回

我安装了rvm但返回 -

不确定该怎么做，会很感激帮助。

您需要root / administrator权限才能写入/及其子目录。你不能在不使用sudo或su的情况下安装任何东西。您的问题或类似问题已在此处得到解答：Installing gem or updating RubyGems fails with permissions error

尝试安装gem，/ Library / Ruby / Gems / .0.0.0目录时没有写权限。已安装RVM
