安装caldecott后，vmc无法正常工作

Question

我使用这个指令来安装caldecott http://docs.cloudfoundry.com/tools/vmc/caldecott.html，但是之后vmc就不起作用了：

/usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require': no such file to load -- restclient (LoadError)
    from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in `require'
    from /var/lib/gems/1.8/gems/tunnel-vmc-plugin-0.1.9/lib/tunnel-vmc-plugin/tunnel.rb:2
    from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require'
    from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in `require'
    from /var/lib/gems/1.8/gems/tunnel-vmc-plugin-0.1.9/lib/tunnel-vmc-plugin/plugin.rb:2
    from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:59:in `gem_original_require'
    from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:59:in `require'
    from /var/lib/gems/1.8/gems/vmc-0.4.2/lib/vmc/plugin.rb:43:in `load_all'
    from /usr/lib/ruby/1.8/set.rb:194:in `each'
    from /usr/lib/ruby/1.8/set.rb:194:in `each_key'
    from /usr/lib/ruby/1.8/set.rb:194:in `each'
    from /var/lib/gems/1.8/gems/vmc-0.4.2/lib/vmc/plugin.rb:42:in `load_all'
    from /var/lib/gems/1.8/gems/vmc-0.4.2/bin/vmc:9
    from /usr/local/bin/vmc:19:in `load'
    from /usr/local/bin/vmc:19

我怎么才能修复它呢？

对于重现：

1. sudo gem install caldecott --no-rdoc --no-ri
2. sudo gem install tunnel-vmc-plugin

由于vmc 0.4是一个新版本，因此在线文档有点过时。您实际需要做的是安装rest-client，尽管这实际上应该依赖于client vmc-plugin！

gem install rest-client

你应该可以走了！
