ruby-on-rails – gem install rails错误：执行gem时…(Errno

我以某种方式搞砸了我的$PATH. (改变了)我的ruby和铁轨宝石不起作用.我在解决这个问题上所做的是重新安装RVM.现在我的ruby在航站楼工作得很好.
在运行gem install rails时我会遇到这样的问题：

许可被拒绝 – /Users/emKaro/.rvm/gems/ruby-2.0.0-p247/gems/atomic-1.1.13/test/test_atomic.rb

当我尝试通过sudo gem install rails安装rails时,我收到此错误：

ERROR: While executing gem … (Errno::EACCES)

我安装了XCode并安装了Command-Line工具.甚至继续安装GCC但在我尝试安装rails时遇到了同样的错误.

这是完整的错误消息

我是我的电脑管理员并运行Mac OS 10.8.3.我很感激rails安装的一些帮助.

编辑：
谢谢@Christoph
唯一有用的代码是实际删除RVM文件夹
sudo rm -rf~ / .rvm /
我只尝试卸载它没有用.因此,删除该文件夹,然后重新安装RVM就可以完成这项工作.

解决方法

就像Dave在那里指出的那样,不需要sudo任何Gem安装.您可以尝试重置RVM目录的权限：

sudo chown -R emKaro: ~/.rvm/

并再次尝试你的宝石安置.如果这不成功,您应该考虑删除RVM安装并重新开始：

sudo rm -rf ~/.rvm/   # remove your RVM directory

在任何一个中都不应该使用sudo.
