在Windows XP上运行gem install RedCloth时，我得到:

为什么会出现此错误？
然后我在
require 'RedCloth'中添加了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)

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
最佳答案
这是我针对第二个错误“无法加载1.9/redcloth_scan”的解决方法，该错误看上去像Windows上的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，您应该使用路径“D:\Programs\Ruby\lib\ruby\gems\1.9.1\gems\RedCloth-4.2.8\lib”替换该目录。
