Python 使用mingw构建第三方库 Unable to find vcvarsall.bat错误解决方法

注意：这里使用的mingw32位版本，如果你的电脑上安装的python amd64位版本，那么请使用mingw64位版本，这个很重要，如果版本不正确，那么会报如下错误。

1	collect2.exe: 错误：ld 返回 1

2	error: command 'gcc' failed with exit status 1

在编译第三方库时，如果第三方库需要编译C文件，那么就需要C编译器，python默认使用microsoft visual studio（VS）编译器编译项目，但是大多数电脑上都没有安装VS程序。这时候，就可以选择另一个轻量级方案（毕竟VS 3个G的安装文件有点得不偿失），使用mingw编译项目。

第一步，下载mingw，这个可以通过百度搜索下载。这里为大家提供一个已经下载好了的压缩文件下载地址

http://pan.baidu.com/s/1mgypfhY

第二步，解压缩mingw压缩文件到任意（不要加压缩到有空格和中文的目录下面）目录。比如D:\mingw下面

第三步，将mingw目录下面的bin文件夹加入到PATH环境变量中。

第四步，测试mingw是否可用

1

gcc -v

通过以上成功安装mingw

那么如何通过mingw构建项目呢

很简单通过如下命令即可

1	python setup.py build --compiler=mingw32

对就是以上命令这么简单。

以下是如果找不到C编译器得到的错误参考（以Tornado库为例）
