推荐答案
Nokogiri 没有 Ruby 2.2.1 的二进制文件可用于 mingw32 平台 由于 交叉编译 Ruby 2.2.1 用于 rake-compiler-dev-box.
Nokogiri doesn't have binaries for Ruby 2.2.1 available for the mingw32 platform due to some problems with cross compiling Ruby 2.2.1 for the rake-compiler-dev-box.
由于 Nokogiri 不能在 Windows 上本地编译，唯一的解决方法是 降级到 Ruby 2.1.5.一旦 Ruby 2.2 的下一个补丁级别发布，希望问题会得到解决.
Since Nokogiri doesn't natively compile on Windows, the only fix is to downgrade to Ruby 2.1.5. Once the next patch level of Ruby 2.2 is released hopefully the problem will be solved.
