One line to rule them all. Power shell not needed. From command prompt run:
一条线统治他们。不需要电源外壳。从命令提示符运行：
ruby -e "`gem list`.split(/$/).each { |line| puts `gem uninstall -Iax #{line.split(' ')[0]}` unless line.empty? }"
Just copy / paste and voila!
只需复制/粘贴，瞧！

You can delete the contents of your gems folder. Where this is will depend on how you installed Ruby and RubyGems, as well as the Ruby version. For instance, if you used the one-click installer for 1.9.2p180, and installed rubygems with ruby setup.rb, the gems folder would be c:\Ruby192\lib\ruby\gems\ - delete everything under that folder and poof! your gems are gone.
您可以删除 gems 文件夹中的内容。这将取决于您安装 Ruby 和 RubyGems 的方式，以及 Ruby 版本。例如，如果您使用 1.9.2p180 的一键安装程序，并使用 ruby setup.rb 安装 rubygems，那么 gems 文件夹将是 c:\Ruby192\lib\ruby\gems\ - 删除该文件夹下的所有内容，噗！你的宝石不见了。

Using gem envon your console will provide something like this:
gem env在您的控制台上使用将提供如下内容：
- GEM PATHS:
- C:/Users/Luis/Tools/ruby/ruby-1.8.7-p334-i386-mingw32/lib/ruby/gems/1.8
If you browse using Explorer into that directory will find a series of folders that represent all the installed gems (cache, doc, spec, gems)
如果您使用资源管理器浏览到该目录，将找到一系列代表所有已安装 gems 的文件夹（cache, doc, spec, gems）
Remove all of them and it will remove all your gems.
删除所有这些，它将删除您所有的宝石。
Now, this will not remove any executable script installed by one of these gems. If you installed rakeor railsgems, these scripts (as railsand rails.batwill remain in your Ruby bindirectory.
现在，这不会删除这些 gem 之一安装的任何可执行脚本。如果您安装了gemsrake或railsgems，这些脚本（asrails并且rails.bat将保留在您的 Rubybin目录中。
You will also need to remove them manually.
您还需要手动删除它们。
