类似于前一篇博文，http://www.cnblogs.com/zhongtang/p/7148082.html中描述的情况。
编译zbarlight同样出现问题，简要处理步骤如下：
1、到https://pypi.python.org/pypi/zbarlight下载源文件。
| File | Type | Py Version | Uploaded on | Size |
|---|---|---|---|---|
| zbarlight-1.2.tar.gz (md5) | Source | 2017-03-09 | 5KB |
2、解压到桌面目录，C:\Users\zou\Desktop\zbarlight\zbarlight-1.2>
修改setup.py文件，增加红色字体三行内容，如下：
ext_modules=[ Extension( name=str(‘zbarlight._zbarlight‘), sources=[str(‘src/zbarlight/_zbarlight.c‘)], extra_compile_args=[‘-std=c99‘], libraries=[‘libzbar-0‘], library_dirs= [‘C:\Program Files (x86)\ZBar\lib‘ ] , include_dirs = [ ‘C:\Program Files (x86)\ZBar\include‘ ], optional=os.environ.get(‘READTHEDOCS‘, False), # Do not build on Read the Docs ), ],
3、手工编译安装，成功：
