我已经为我的Django应用程序运行了gcloud app deploy，但是在构建日志末尾它失败并出现以下错误：

当我根据GitHub上的changelog为python 3.7提供了更大的支持时，我曾尝试将pywin32版本降级到223，但是每次重试都出现了相同的构建日志错误，并替换了版本。
我不太确定到底怎么了。 GCP为什么找不到合适的发行版？
还有可能相关的问题，为什么在最终IOError之前的回溯会在python2.7目录中列出runpy.py文件？我在app.yaml中将运行时python指定为3.7，并且在编写所有内容时都考虑了python3 ...
感谢您的帮助，如果我在这里遗漏了一些明显的东西，对不起。在过去的几个小时里，我一直在动脑筋，无济于事：（
pywin32程序包仅发布Windows平台的内置发行版（请注意所有win*文件名here）。
您将无法在App Engine上安装它，因为基础平台是Linux，而不是Windows。
