wfastcgi 在 Win7 上的 IIS 中找不到 flask 应用程序

Question

我正在尝试在适用于Windows 7的IIS6上设置wfastcgi，但它找不到我的"app.py"文件。我使用 http://netdot.co/2015/03/09/flask-on-iis/作为设置它的方向。以下是我收到的错误消息。在寻找答案的过程中，最有可能的解决方案是这是一个权限问题，我相信我正确授予了权限，但仍然没有运气。

Error occurred while reading WSGI handler:
Traceback (most recent call last):
File "C:inetpubwwwrootFlask_Projwfastcgi.py", line 712, in main env, handler = read_wsgi_handler(response.physical_path)
File "C:inetpubwwwrootFlask_Projwfastcgi.py", line 569, in read_wsgi_handler return env, get_wsgi_handler(handler_name)
File "C:inetpubwwwrootFlask_Projwfastcgi.py", line 552, in get_wsgi_handler raise ValueError('"%s" could not be imported' % handler_name)
ValueError: app.app could not be imported StdOut: StdErr: 

这是Web.config文件

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <appSettings>
    <add key="WSGI_HANDLER" value="app.app" />
    <add key="PYTHONPATH" value="C:inetpubwwwrootFlask_Proj" />
  </appSettings>
    <system.webServer>
        <handlers accessPolicy="Read, Script">
            <add name="FlaskHandler" path="*" verb="*" modules="FastCgiModule" scriptProcessor="C:Python34python.exe|C:inetpubwwwrootFlask_Projwfastcgi.py" resourceType="Unspecified" requireAccess="Script" />
        </handlers>
    </system.webServer>
    </configuration>

此外，为了让您的生活更轻松，以下是 wfastcgi.py 文件的代码片段：

def get_wsgi_handler(handler_name):
    if not handler_name:
        raise Exception('WSGI_HANDLER env var must be set')
    if not isinstance(handler_name, str):
        if sys.version_info >= (3,):
            handler_name = handler_name.decode(sys.getfilesystemencoding())
        else:
            handler_name = handler_name.encode(sys.getfilesystemencoding())
    module_name, _, callable_name = handler_name.rpartition('.')
    should_call = callable_name.endswith('()')
    callable_name = callable_name[:-2] if should_call else callable_name
    name_list = [(callable_name, should_call)]
    handler = None
    while module_name:
        try:
            handler = __import__(module_name, fromlist=[name_list[0][0]])
            for name, should_call in name_list:
                handler = getattr(handler, name)
                if should_call:
                    handler = handler()
            break
        except ImportError:
            module_name, _, callable_name = module_name.rpartition('.')
            should_call = callable_name.endswith('()')
            callable_name = callable_name[:-2] if should_call else callable_name
            name_list.insert(0, (callable_name, should_call))
            handler = None
    if handler is None:
        raise ValueError('"%s" could not be imported' % handler_name)
    return handler

我明白了我做错了什么。这是一个愚蠢的错误，但根据我的搜索，我可能不是唯一一个。我安装了python，但我没有安装Flask。一旦我明白了运行其他所有内容就容易弄清楚了。
