我正在运行以下命令来安装mongrel（对于应用程序，将ruby降级为1.8.7p302，当尝试进行捆绑创建--local时，它要求安装mysql，然后要求mongrel）gem install win32-open3 -v '0.3.2'
(master) $ gem install mongrel -v '1.1.5'
Building native extensions. This could take a while...

Results logged to /usr/local/rvm/gems/ruby-2.1.5@rails4/extensions/x86_64-linux/2.1.0/mongrel-1.1.5/gem_make.out
最佳答案
转到cd /usr/local/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5/ext/http11
并在http11.c上使用sudo nano或vi以及：
用77代替
for（ch = RSTRING_PTR（f），end = ch + RSTRING_LEN（f）; ch 接着
将172行替换为
冒号= strchr（RSTRING_PTR（temp），'：'）;
将174行替换为
rb_hash_aset（req，global_server_name，rb_str_substr（temp，0，冒号-RSTRING_PTR（temp）））;
替换行176,177
rb_str_substr（temp，冒号-RSTRING_PTR（temp）+1，
RSTRING_LEN（temp）））；
更换线298299
dptr = RSTRING_PTR（数据）;
dlen = RSTRING_LEN（数据）;
保存文件，
sudo ruby extconf.rb && sudo make && sudo make安装
转到cd ../../lib/mongrel
（或完整路径“ /usr/local/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5/lib/mongrel”
须藤纳米处理程序
修复案例陈述
在第208-212行，将“：false”的实例更改为“ then false”
然后sudo gem install mongrel如果构建失败
像这样第二种选择
您可以像这样强制安装杂种
sudo gem install mongrel -v 1.2.0.pre2---with-cflags = \“-O2 -pipe -march = native -w \”
这对我有用，希望对您也有用。
