运行时gem install RedCloth（在 Windows XP 上）我得到：

Fetching: RedCloth-4.2.8.gem (100%)

为什么我会收到此错误？

然后我添加require 'RedCloth'到config/environment.rb，并尝试运行rails s，但不幸的是我得到了：

D:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/RedCloth-4.2.8/lib/redcloth.rb:12:in `
require': no such file to load -- 1.9/redcloth_scan (LoadError)
Couldn't load 1.9/redcloth_scan
The $LOAD_PATH was: ...

我究竟做错了什么 ？

我使用 Rails 3.0.1、Ruby 1.9.2。

bundle show RedCloth

=> D:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/RedCloth-4.2.8

这是我对您的第二个错误“无法加载 1.9/redcloth_scan”的解决方法，它看起来像 Windows 上的 RedCloth 错误。之后gem install RedCloth --no-rdoc，我跑

cd c:\Ruby192\lib\ruby\gems\1.9.1\gems\RedCloth-4.2.8\lib
mkdir 1.9
copy redcloth_scan.so 1.9

当然，您应该将该目录替换为您的路径“D:\Programs\Ruby\lib\ruby\gems\1.9.1\gems\RedCloth-4.2.8\lib”。

请务必根据错误消息命名目录。例如对于 Ruby 2.1 和

LoadError: cannot load such file -- 2.1/redcloth_scan

应该在“lib”目录中创建目录“2.1”并复制redcloth_scan.so到它
