由于 MarkupSafe，gcloud 应用部署失败

Question

我正在使用“gcloud”将我的烧瓶应用程序部署到 GCP APP 引擎并收到以下错误：

Step #1: Collecting MarkupSafe==1.0 (from -r requirements.txt (line 6))

似乎目标 VM 使用的是 PIP 9 而不是最新的 PIP 18。

有没有办法避免这个错误？

好像是系统bug：Why does pip freeze list "pkg-resources==0.0.0"?

解决方案是从 Flask 项目的“requirements.txt”中删除“pkg-resources==0.0.0”。
