Answer 1

如果在Windows上需要安装Ruby DevKit，请从http://rubyinstaller.org/downloads/获取它（向下滚动一点）。

Answer 2

同样的故事在这里删除ruby并安装：

• Ruby 2.0.0-p247
• 的devkit-mingw64-32-4.7.2-20130224-1151-sfx.exe

来自http://rubyinstaller.org/downloads/的

解决了这个问题。

Answer 3

尝试使用http://railsinstaller.org/中的railsinstaller 它会安装下面的

Ruby 1.9.3-p392
Rails 4
Bundler
Git
Sqlite
TinyTDS
SQL Server Support
DevKit

Answer 4

当您尝试组合32位Ruby和64位DevKit时，也会发生同样的情况。 解决方案是使用相同位版本。

例如当前版本： rubyinstaller-2.0.0-P247-x64.exe程序 的devkit-mingw64-64-4.7.2-20130224-1432-sfx.exe
