ruby-on-rails - 无法加载此类文件 — ruby​​gems.rb

Question

要打开这个项目 (revel)，我需要使用 ruby​​-2.1.2。我同时安装了 ruby​​-2.1.0 和 ruby​​-2.1.2，但我认为 2.1.2 版本由于某种原因已损坏，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>'

当我尝试卸载以重新安装时，我得到:

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

++ rvm_debug '__rvm_rm_rf error removing target dir '\''/Users/lianoosh/.rvm/rubies/ruby-2.1.2'\''.'
++ ((  0  ))
++ return 0
++ 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，我得到:

Already installed ruby-2.1.2.
To reinstall use:

    rvm reinstall ruby-2.1.2

当我这样做时，我收到一堆权限被拒绝的消息和目录不为空，然后直接回到我开始的地方。还有:

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!
