安装Curl，Curb Gem时出错？

Question

我试图在Ruby上安装Curb Gem，并得到了以下错误：

C:\Sites>gem install curb -- -- --with-curl-lib=C:\curl-7.34-devel-mingw32\bin -
-with-curl-include=C:\curl-7.34.0-devel-mingw32\include
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing curb:

    C:/RailsInstaller/Ruby1.9.3/bin/ruby.exe extconf.rb -- --with-curl-lib=C

*** extconf.rb failed ***
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:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=C:/RailsInstaller/Ruby1.9.3/bin/ruby
    --with-curl-dir
    --without-curl-dir
    --with-curl-include=${curl-dir}/include
    --with-curl-lib=${curl-dir}/lib
    --with-curllib
    --without-curllib
extconf.rb:23:in `<main>':   Can't find libcurl or curl/curl.h (RuntimeError)

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

我安装的一切都像别人说的那样，我真的很迷茫:(我真的想让它工作.我在windows 7 x64上，但是我的红宝石安装是32位的(我发现，由于某种原因，我只使用32位红宝石)。

现在我正在安装MinGW的东西--我甚至不知道在里面下载什么，我只是在基本安装中安装了所有的东西.

在Ubuntu上，我不得不跑：

sudo apt-get install build-essential libcurl4-openssl-dev

尝试安装这些库及其依赖项。
