无法导入 pyrebase GAE答案

【问题标题】：Cannot import pyrebase GAE无法导入 pyrebase GAE
【发布时间】：2022-01-24 00:34:19
【问题描述】：

我有一个可以在本地完美运行的应用程序。但是，出于某种原因，在 GAE（标准 python37）中，导入 pyrebase（requirements.txt 中的 pyrebase==3.0.27）似乎存在问题。知道如何解决这个问题吗？

提前致谢！

【问题讨论】：

发现几篇帖子说pyrebase 3.0.27 与python 3 不兼容。你试过pip install Pyrebase4 吗？如果它不起作用，请尝试使用pip uninstall pyrebase 卸载 pyrebase，然后安装 Pyrebase4。如果这些步骤仍未解决您的错误，请提供可重现的代码以及您的app.yaml 和requirements.txt。
谢谢@MabelA。！从 pyrebase==3.0.27 更改为 Pyrebase4==4.5.0 解决了问题！

【解决方案1】：

Pyrebase 3.0.27 与 Python 版本 3 存在兼容性问题。请改用最新版本的Pyrebase：Pyrebase4。

OP 通过更改 requirements.txt 中的 Pyrebase 版本解决了这个问题：

从pyrebase==3.0.27 到Pyrebase4==4.5.0
