gem install mongrel在ruby 1.9.1上失败

Question

昨天我开始了Rails开发。
我安装了Ruby 1.9.1、RubyGems和Rails。
运行gem install mongrel没有问题，而且表面上也安装了Mongrel。我有点困惑，因为：

• script/server默认启动Webrick
• which mongrel返回空
• locate mongrel返回很多类似的条目

看起来我已经安装了mongrel（默认安装和自定义安装都有）。那为什么“which mongrel”没有返回任何东西呢？

另外尝试使用gem install mongrel重新安装mongrel会产生一系列异常：

Answer 1

您可以使用 sudo gem install mongrel --pre 安装 Mongrel 1.2 预发布版:

$ sudo gem1.9 install mongrel --pre
> 正在构建本地扩展，可能需要一段时间...
> mongrel-1.2.0.pre2 安装成功
> 已安装 1 个宝石

看起来有其他人在Ruby 1.9上运行Mongrel时遇到了问题。

Ami Mahloof的评论似乎是一个可能的解决方法：

以下是您需要执行以修复此问题的步骤

以下是更新后的说明：

1）cd /usr/local/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5/ext/http11

2）sudo vi / mate on http11.c 并：

将第77行替换为

for(ch = RSTRING_PTR(f), end = ch + RSTRING_LEN(f); ch < end; ch++) {

将第172行替换为

colon = strchr(RSTRING_PTR(temp), ':');

将第174行替换为

rb_hash_aset(req, global_server_name, rb_str_substr(temp, 0, colon - RSTRING_PTR(temp)));

将第176、177行替换为

rb_str_substr(temp, colon - RSTRING_PTR(temp)+1, RSTRING_LEN(temp)));

将第298、299行替换为

dptr = RSTRING_PTR(data);

dlen = RSTRING_LEN(data);

3）保存文件，关闭vi / textmate

4）sudo ruby extconf.rb && sudo make && sudo make install

5）cd ../../lib/mongrel (或完整路径“/usr/local/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5/lib/mongrel”

6）mate / sudo vi handlers.rb

7）更正中的case语句

在208-212行，将“：false”的实例更改为“then false”

8）sudo gem install gem_plugin（否则mongrel可能会挂起）

完成！

Answer 3

这是一个编译问题，因此做起来更容易：

git clone git://github.com/mongrel/mongrel.git

cd mongrel/ext/http/

现在编辑http11.c文件：

#ifndef RSTRING_PTR
#define RSTRING_PTR(s) (RSTRING(s))
#endif
#ifndef RSTRING_LEN
#define RSTRING_LEN(s) (RSTRING(s))
#endif

保存它，然后在同一个目录下执行以下操作：

sudo ruby extconf.rb && sudo make && sudo make install

完成！

您可以强制安装 Mongrel，方法如下：

sudo gem install mongrel -v 1.2.0.pre2 -- --with-cflags=\"-O2 -pipe -march=native -w\"

这样就解决了问题。
