不小心运行$ gem update –system后无法运行rails服务器
我跑了gem update --system认为它会解决我遇到的问题，现在我无法运行rails server 。 它不会加载，而是我继续得到以下。 有人可以告诉我如何撤消这个并恢复到我运行更新之前？
我已经运行了git checkout ，但问题仍然存在……
/usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.1.5/lib/bundler/rubygems_integration.rb:187:in `stub_source_index170': uninitialized constant Gem::SourceIndex (NameError) from /usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.1.5/lib/bundler/rubygems_integration.rb:353:in `stub_rubygems' from /usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.1.5/lib/bundler/rubygems_integration.rb:250:in `replace_entrypoints' from /usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.1.5/lib/bundler/runtime.rb:14:in `setup' from /usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.1.5/lib/bundler.rb:107:in `setup' from /usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/rubygems-bundler-1.0.7/lib/rubygems-bundler/noexec.rb:66:in `setup' from /usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/rubygems-bundler-1.0.7/lib/rubygems-bundler/noexec.rb:78:in `' from /usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:110:in `require' from /usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:110:in `rescue in require' from /usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:35:in `require' from /usr/local/rvm/gems/ruby-1.9.3-p194/bin/ruby_noexec_wrapper:9:in `'
好像最新版本的Rubygems是错误的。
您只需使用以下命令恢复到旧版本，一切都应该正常工作：
gem update --system 1.8.24
我今天遇到了同样的问题。 将bundler更新到最新版本修复了问题：
gem update bundler
如果你正在运行rbenv
rbenv rehash
