清理我的RoR开发环境

Question

几个月前，我开始了RoR的开发，并且是一个新手……

时间过得很快，现在我有很多不同的ruby版本，rails版本和gem版本位于everywhere......And目前我安装了rvm，事情变得更糟，所有的事情都搞砸了！

所以我开始想要清理所有的东西，并再次使用rvm！我想卸载所有的gem、所有的rails和所有的ruby版本，除了系统的默认版本(mac附带的非常旧的版本)。

或其他更好的解决方案或建议！？请帮帮我！

这里有一些我认为有用的信息：

which -a ruby

/opt/local/bin/ruby
/opt/local/bin/ruby
/usr/local/bin/ruby
/usr/bin/ruby
/usr/local/bin/ruby

which -a rails

/usr/local/bin/rails
/usr/bin/rails
/usr/local/bin/rails

which -a compass # simliar for rspec and many other gems

/usr/local/bin/compass
/usr/local/bin/compass

gem list

哇，嗯..。你已经..。啊..。很忙。尝试清理这些东西将是一个挑战，而且可能超出我们的能力范围，除非我们可以查看大量的系统目录和您的帐户的配置。

我的第一个问题是:您是否在/usr/bin/ruby中对系统的默认Ruby进行了任何更改？如果是这样的话，我个人只需要备份我想要保存的数据，然后擦除驱动器，然后重新开始。

你运行过gem clean吗？这将删除一堆垃圾，但也可能会引发许多关于依赖关系的问题，并且，当完成时，可能会使事情变得不完整或不变-很难说有这么多的gem和修订会发生什么。

您可以使用如下命令强制gem卸载所有gem：

gem list | awk '{print $1}' | xargs gem --all --quiet uninstall

只需确定哪个Ruby版本正在运行，因为gem将针对当前运行的Ruby执行操作。使用which ruby找出答案。
