Bluecloth v2.0.10与Windows 7无法正常工作

在Ruby 187中，我从http://rubyinstaller.org/downloads下载了devkit，并按照https://github.com/oneclick/rubyinstaller/wiki/Development-Kit的说明进行操作。 我还确保通过以下烟雾测试正确安装devkit。

然后我尝试安装蓝布（v2.0.10）。 它失败了以下错误：

如果您需要2.2.0（最新版本），请按以下步骤操作：

  1. 安装DevKit

  2. 运行以下命令安装蓝布：

    gem install bluecloth

    在构建“原生扩展”时，这将失败，但会成功安装gem的源代码。

  3. 补丁bluecloth.h文件（对我来说，这可以在：D：\ ruby​​ \ Ruby-1.9.3-p125 \ lib \ ruby​​ \ gems \ 1.9.1 \ gems \ bluecloth-2.2.0 \ ext）中找到来自这里的补丁： https ： //gist.github.com/1539611

  4. 转到bluecloth的gem安装文件夹。 对我来说，这看起来如下：

    D:\ruby\Ruby-1.9.3-p125\lib\ruby\gems\1.9.1\gems\bluecloth-2.2.0

  5. 运行以下命令：

    rake gem

    它可能会提示您安装其他一些gem，请相应地遵循。 完成后，您应该看到创建了bluecloth-2.2.0.gem。 对我来说，它在这里找到：

    D:\ruby\Ruby-1.9.3-p125\lib\ruby\gems\1.9.1\gems\bluecloth-2.2.0\pkg\bluecloth-2.2.0.gem

  6. 转到bluecloth-2.2.0.gem位置，然后运行以下命令：

    gem install bluecloth-2.2.0.gem --platform=ruby

似乎BlueCloth的2.0.10版本存在错误/问题。 您可以尝试使用2.0.7之类的旧版本： 

 gem install bluecloth -v 2.0.7

这似乎工作。

也许这值得检查最新版本（2.2.0？），如果不能正常工作，请将其报告给gem作者：

这是修补的bluecloth.h代码，适用于匆忙的人…… 

 #ifndef BLUECLOTH_H #define BLUECLOTH_H #include "ruby.h" #if defined(HAVE_RUBY_ENCODING_H) && HAVE_RUBY_ENCODING_H # define M17N_SUPPORTED # include "ruby/encoding.h" #endif #include "config.h" #include "assert.h" #include "mkdio.h" void mkd_initialize _(( void )); void mkd_with_html5_tags _(( void )); /* Replace the macro from encoding.h that refers to static 'rb_encoding_list' */ #ifdef ENC_FROM_ENCINDEX #undef ENC_FROM_ENCINDEX #define ENC_FROM_ENCINDEX(idx) (rb_enc_from_index(idx)) #endif #endif

github上有一个已经包含补丁的分支：
