如何在Windows上安装RedCloth？

Question

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

Fetching: RedCloth-4.2.8.gem (100%)
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
Successfully installed RedCloth-4.2.8

 --charset=UTF-8 --line-numbers --title RedCloth --main README.rdoc lib lib/case
_sensitive_require ext README.rdoc COPYING CHANGELOG --title RedCloth-4.2.8 Docu
mentation --quiet

为什么会出现这个错误？

然后我将require 'RedCloth'添加到config/environment.rb中，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？

我使用的是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

Answer 1

这是我对你的第二个错误的解决办法，“无法加载1.9/ RedCloth _scan"，它看起来像是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

您应该用您的路径替换该目录，当然是"D:\Programs\Ruby\lib\ruby\gems\1.9.1\gems\RedCloth-4.2.8\lib"，。

Answer 2

请确保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

用户应该在"lib“目录中创建目录"2.1"，并将redcloth_scan.so复制到其中
