无法在Azure上部署基本的Python 3.6 - web.config？

Question

我目前正在向Azure发布一个非常基本的烧瓶应用程序，尽管我在Google上找到了什么，但我几天都没有成功。

我的架构非常简单（我将在下面显示，因为我不认为它是问题的根源）并且我有一个web.config文件：

文件“web.config”：

<?xml version="1.0"?>
<configuration>
  <appSettings>
    <add key="WSGI_HANDLER" value="MentorQuestFlask.app"/>
    <add key="PYTHONPATH" value="D:homesitewwwroot"/>
    <add key="WSGI_LOG" value="D:homeLogFileswfastcgi.log"/>
  </appSettings>
  <system.webServer>
    <handlers>
      <add name="PythonHandler" path="handler.fcgi" verb="*" modules="FastCgiModule" scriptProcessor="D:homepython364x64python.exe|D:homepython364x64wfastcgi.py" resourceType="Unspecified" requireAccess="Script"/>
    </handlers>
    <rewrite>
      <rules>
        <rule name="Static Files" stopProcessing="true">
          <conditions>
            <add input="true" pattern="false" />
          </conditions>
        </rule>
        <rule name="Configure Python" stopProcessing="true">
          <match url="(.*)" ignoreCase="false" />
          <conditions>
            <add input="{REQUEST_URI}" pattern="^/static/.*" ignoreCase="true" negate="true" />
          </conditions>
          <action type="Rewrite" url="handler.fcgi/{R:1}" appendQueryString="true" />
        </rule>
      </rules>
    </rewrite>
  </system.webServer>
</configuration>

在Azure中我添加了扩展名：Python 3.6.4 x64另外在另一个线程中我在配置选项卡中添加了Python 3.6：picture of the configuration zone

同样在Path Mappings中我添加了：

扩展名：fastCgi

脚本处理器：D： home python362x86 python.exe

参数：D： home python362x86 wfastcgi.py

最后，在应用程序设置中，WEBSITE_USE_PLACEHOLDER设置为0。

但没有任何工作。在网站上，我看到以下错误：

“由于发生内部服务器错误，无法显示页面。”

所以我用Kudu来显示以下内容（在本文下面）

我的问题是：

似乎没有安装包（烧瓶错误）
web.config似乎未正确配置。

我已经尝试了几种不同的配置，但没有一种方法可行，而且我的想法很缺乏......

谢谢你的帮助或建议？

问候，

查尔斯
