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

为什么会出现此错误？
然后我将 require 'RedCloth' 添加到 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
最佳答案
这是我解决第二个错误“无法加载 1.9/redcloth_scan”的解决方法，它看起来像是 Windows 上 RedCloth 的错误。在 gem install RedCloth --no-rdoc 之后，我运行
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”。
