在Windows上的Ruby：未初始化的常量Process :: Functions :: FFI（NameError）

Question

我在Windows上运行ruby，通过ruby安装程序安装了1.9.3。我已经安装了chef红宝石，但是我不能在命令行中使用chef-client或knife。

以下是命令行的删节输出。出了什么问题？

C:\>chef-client 
C:/ruby193/lib/ruby/gems/1.9.1/gems/windows-api-0.4.0/lib/windows/api.rb:4: Use RbConfig instead of obsolete and deprecated Config.

P.版本号：

C:\>ruby -v 
ruby 1.9.3p374 (2013-01-15) [i386-mingw32] 

C:\>gem -v 
2.1.8

如果你使用的厨师11.6.2（最新版本），你可能要降级到11.6.0。 11.6.2使用mixlib-shellout，但不幸的是只有1.1，并且FFI依赖的版本非常低。降级到11.6.0应该暂时解决这个问题，他们的主分支现在正在使用mixlib-shellout 1.2，所以它应该很快就会得到解决......
