Question

我写了一个python c扩展来实现PEP302来定义我自己的meta_path钩子和路径钩子，这样我就可以加载加密python模块

// c扩展代码http://pastie.org/private/c2tslasqg6omph2i88oug

我修改了site.py（python -c“import site; print site .__ file__”），附加两行：

sys.path.append('/opt/pycode-encrypt')
import hacksite

// hacksite code http://pastie.org/private/epfsnfgz7fwhdwavtqxvw

现在的问题是：当我使用原始代码启动芹菜工人时，一切都很好但当我用我的扩展加密代码，然后我用--autoreload启动芹菜工作者，我有一些错误：

    raise ValueError('unsupported hash type %s' % name)
ValueError: unsupported hash type md5

但在python交互模式下，我可以导入_hashlib，我可以无误地运行_hashlib.new（'md5'，'msg'）。
错误恰好发生在芹菜工人身上--autoreload params

我也做了一些测试，我发现：
我修改/ usr / bin / celery添加一些测试代码尝试使用_hashlib.new并且没问题。但是celery/worker/autoreload.py#file_hash中的相同代码会引发ValueError。

我是python c扩展开发的新手，我为这个问题工作了一段时间，我找不到一些有用的东西来解决这个问题。

所以我来这里寻求帮助。

谢谢

ValueError：不支持的哈希类型md5
