安装报错（这里贴的代码是测试安装报错的代码，因为正式安装代码太多、太杂了）：

 [root@centos Pillow-2.1.0]# python setup.py build_ext -i running build_ext
**error: in 'ext_modules' option (extension 'PIL._imaging'), 'sources' must be present and must be a list of source filenames**

求大神帮助

看一下你的ext_modules参数是怎么设置的

@oyljerry 你好，以下是我的参数

    version=VERSION,

    long_description=(

        _read('docs/CONTRIBUTORS.txt')).decode('utf-8'),
    author='Alex Clark (fork author)',
    author_email='aclark@aclark.net',

@oyljerry
我看了一下他的代码，其中这句是关键：

 ext_modules=[Extension("PIL._imaging", ["_imaging.c"])]

之后我在PIL目录中没有发现 _imaging 这个模块(文件)，这个包可是我从官网下载下来的，不知道怎么会错请求帮助
