google-app-engine - [No module named 'google.appengine' appengine 本地开发错误

问题描述

我正在从 python27 迁移到 python37。我已将 python2 代码移植到 python3 代码。问题是当我尝试运行开发服务器时，它说ModuleNotFoundError: No module named 'google.appengine'。我已经下载了谷歌云 sdk。

我还下载了以下谷歌库：

google==2.03; google-api-core==1.17.0; google-auth==1.14.3; google-cloud==0.34.0; google-cloud-core==1.3.0; google-cloud-datastore==1.120; google-cloud-ndb==1.2.0; google-cloud-storage==1.28.0;

我正在使用 CLOUD_DATASTORE。这和那个有关系吗？我必须迁移吗？

这是完整的错误：

解决方案

该google.appengine模块被烘焙到第一代 Python (2.7) 运行时中。pip在第二代 (3.7) 运行时或任何 Docker 环境中都无法通过 安装。

使用它的唯一方法是编写和部署第一代 App Engine 应用程序。

根据您正在执行的操作，您应该能够将其替换为客户端库调用。
