但是 - 如果我尝试接受其中一个建议，它会失败

$ gem pristine nokogiri --version 1.6.6.2

ERROR:  While executing gem ... (Gem::Exception)
    Failed to find gems ["nokogiri"] = 1.6.6.2

我尝试在不指定版本的情况下安装 nokogiri 和其他扩展程序，并且可以正常工作，但是当我运行命令时没有解决任何问题。

【问题讨论】：

我们建议您使用 ChefDK 安装程序在您的工作站上安装 Chef，其中包括他们自己的 Ruby 环境和已知的安全 gem 集合。
我确实使用了 chefdk 安装程序，但我似乎仍然遇到这些错误。 $ ls -l $(which knife) lrwxr-xr-x 1 root admin 21B Jul 22 15:57 /usr/local/bin/knife@ -> /opt/chefdk/bin/knife
NM，看起来我的系统 ruby 没有设置为 chefdk ruby - 一旦我更新它 - 它就修复了它。

问题已通过使用 ChefDK Ruby 而不是系统默认的 Ruby 得到解决。

请展开！我可以输入什么来修复同样的错误？
具体情况取决于您当前的设置，但大多数情况下只是安装 ChefDK，不要胡思乱想。
什么是 ChefDK？
