Cloud Build无法构建App Engine Python 3.8应用程序由于pip错误？

问题描述

我在Google App Engine标准上有许多Python 3.7应用程序，都可以正常构建和部署。我正在尝试将其中一些升级到new Python 3.8 runtime，但是当我尝试进行部署时，它们在Cloud Build中失败。

看起来他们正在击中this open pip bug（more background）。奇怪的是，只有Python 3.8运行时会触发此错误，而3.7可以很好地构建。

完整日志如下。（请注意，这是在Cloud Build中发生的，而不是在本地计算机中发生的，因此我无法升级pip或更改任何命令或环境。）有人知道我可以如何解决或解决此问题？

这是我的requirements.txt文件。我怀疑-e .可能是问题所在...但是它在Python 3.7中有效，因此，如果这样，那真令人失望。
