Google Cloud App Engine：“python setup.py egg_info”处的云构建失败

Question

我正在尝试使用烧瓶部署一个用 python3.6 编写的谷歌云应用引擎应用程序。

这是错误：

我搜索了一下，发现这个错误是因为pip版本过时造成的。但是，我将 pip==10.0.1 放在了我的 requirements.txt 中，但它仍然不起作用。

有没有办法远程运行pip install --upgrade pip？如果是这样，我该怎么做？

编辑：

这是我的清单文件 app.yaml：

runtime: python
env: flex
entrypoint: gunicorn -b :$PORT main:app

runtime_config:
  python_version: 3

manual_scaling:

  cpu: 1
  memory_gb: 0.5
  disk_size_gb: 10

我今天早些时候遇到了这个问题，我只安装了我需要的 google-cloud 包（在我的例子中是google-cloud-pubsub 和google-cloud-storage）来解决这个问题。看起来伞 google-cloud 包无论如何都已被弃用。来源：https://pypi.org/project/google-cloud/

警告：不推荐使用 google-cloud Python 包。 2018 年 6 月 18 日，此软件包将不再安装任何其他软件包。请安装您的应用程序所需的产品特定的 google-cloud-* 软件包。
