无法加载此文件——rubygems.rb。

为了打开这个项目(revel)，我需要使用ruby-2.1.2版本。我已经安装了ruby-2.1.0和ruby-2.1.2，但是我认为2.1.2版本由于某种原因已经损坏，我似乎无法使用它。

|~/desktop/ix/projects/revel> rvm use 2.1.2
Using /Users/lianoosh/.rvm/gems/ruby-2.1.2
<internal:gem_prelude>:1:in `require': cannot load such file -- rubygems.rb (LoadError)
    from <internal:gem_prelude>:1:in `<compiled>'

|~/desktop/ix/projects/revel> gem list
<internal:gem_prelude>:1:in `require': cannot load such file -- rubygems.rb (LoadError)
    from <internal:gem_prelude>:1:in `<compiled>'

|~/desktop/ix/projects/revel> gem update --system 
<internal:gem_prelude>:1:in `require': cannot load such file -- rubygems.rb (LoadError)
    from <internal:gem_prelude>:1:in `<compiled>'

当我尝试卸载以便重新安装时，出现以下错误：

|~/desktop/ix/projects/revel> rvm uninstall 2.1.2
ruby-2.1.2 - #removing rubies/ruby-2.1.2............................................................................................................................|

++ return 1
然后：
|~/desktop/ix/projects/revel> rvm list

rvm rubies

   ruby-2.1.0 [ x86_64 ]
=* ruby-2.1.2 [ missing bin/ruby ]

# => - current
# =* - current && default
#  * - default

所以当我尝试重新安装时，会出现以下错误：

Already installed ruby-2.1.2.
To reinstall use:

    rvm reinstall ruby-2.1.2

当我这样做时，我会得到一堆权限被拒绝的消息和目录不为空的消息，并立即回到起点。

另外：

Empty path passed to certificates update, functions stack: requirements_osx_update_openssl_cert_run rvm_requiremnts_fail_or_run_action __rvm_osx_ssl_certs_ensure_for_ruby __rvm_osx_ssl_certs_ensure_for_ruby_except_jruby external_import_setup external_import main

请帮忙！

不是直接回答，但我发现使用rbenv来管理版本比rvm简单得多。 - Matt

试一下这个：

rvm fix-permissions

rvm reinstall 2.1.2

今天我也遇到了这个问题，但重新安装Ruby并不是正确的解决方法，因为昨天一切都运行正常。

根据错误提示，我只需更新RubyGem即可。更新后问题得以解决。

gem install rubygems-update

update_rubygems

与破损的 Ruby 相关的问题，在 RVM 的情况下可以通过一种非常简单但不整洁的方法解决 - rvm 重新安装。您需要移除 RVM 和所有的 rubies。请参考这个 文章。
