无法在Windows 8上安装nokogiri ruby​​gem。

Question

所以我安装了ruby（x.0的2.0.0）和DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe并确保它能够安装json ruby​​gem。我在管理员帐户中下载了ruby.exe，并以管理员身份运行命令行。我一直在谷歌搜索这个问题一个小时，但没有修复它！任何帮助将不胜感激。

Answer 1

你是如何安装Ruby的，先尝试用rubyinstaller安装它，看看你是否还有问题。

Answer 2

Nokogiri尚不支持64位计算机上的Windows Ruby 2.0。跟随https://github.com/sparklemotion/nokogiri/issues/864

Answer 3

您使用64位devkit安装了32位ruby。再试一次，但要确保它们匹配。

Answer 4

您可以尝试'fat binary gem'。
