Google compute engine ImportError:没有名为google.appengine.ext的模块

我刚刚得到了发布管道与谷歌的推动部署在应用程序引擎

我发布了我的一些单元测试失败的消息

======================================================================
ERROR: Failure: ImportError (No module named google.appengine.ext)

我犯了以下错误

ImportError: No module named google.appengine.ext

我登录到VM并注意到文件位于，例如：

var/lib/docker/aufs/mnt/bbc6deda44e4806c5c0e377df6f1109733e382e8531c1c9ed440084d8e98e3fe/google-cloud-sdk/platform/google_
appengine/google/appengine/ext/ndb/utils.py

---

如何在VM中普遍使用路径？

这样我就可以从VM的python REPL中的google.appengine.ext导入。然而，我仍然看到失败的单元测试与相同的错误可能重复

var/lib/docker/aufs/mnt/bbc6deda44e4806c5c0e377df6f1109733e382e8531c1c9ed440084d8e98e3fe/google-cloud-sdk/platform/google_
