ruby-on-rails - Bluecloth v2.0.10 与 Windows 7 不工作

Question

使用 Ruby 187，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。我还通过烟雾测试确保正确安装了 devkit。

然后我尝试安装 bluecloth (v2.0.10)。它因以下错误而失败：

C:\test\typo>gem install bluecloth --platform=ruby

Answer 1

如果您需要 2.2.0（最新版本），这是我如何让它工作的：

1. 安装DevKit

2. 运行以下命令来安装 bluecloth：

   gem install bluecloth

   在构建“本机扩展”时，这将失败，但会成功安装 gem 的源代码。

3. 修补bluecloth.h文件（对我来说，它位于：D:\ruby\Ruby-1.9.3-p125\lib\ruby\gems\1.9.1\gems\bluecloth-2.2.0\ext），带有补丁从这里：https ://gist.github.com/1539611

4. 转到 bluecloth 的 gem 安装文件夹。对我来说，这如下所示：

   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，请相应地进行操作。完成后，您应该会看到创建了一个 bluecloth-2.2.0.gem。对我来说，它可以在这里找到：

   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

Answer 2

BlueCloth 2.0.10 版似乎存在错误/问题。您可以尝试使用像 2.0.7 这样的旧版本：

gem install bluecloth -v 2.0.7

这似乎有效。

也可能这值得检查最新版本（2.2.0？），如果不起作用，请将其报告给 gem 作者：

Answer 3

这是修补过的 bluecloth.h 代码，供赶时间的人使用...

#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fork：
