在项目里面引入了patron，无奈使用

gem install patron -v 0.4.18 安装的时候一直报错，提示信息如下

e:\ATT\Devkit>
e:\ATT\Devkit>gem install patron -v 0.4.18
Temporarily enhancing PATH to include DevKit...

ERROR:  Error installing patron:
        ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:

  Try passing --with-curl-dir or --with-curl-lib and --with-curl-include
  options to extconf.


Gem files will remain installed in E:/ATT/ATT_rake_server_ruby187/ruby/lib/ruby/

异常原因：

没有将curl库编译进去，导致无法安装

解决方法：

在gem 后面加上如下格式参数

gem install --local patron-0.4.18.gem<strong><span style="color:#ff0000;"> -- --with-curl-lib="..\curl\bin" --with-curl-include="..\curl\include"</span></strong>
