我的代码昨天工作得很好，今天由于pyrebase崩溃，我无法启动它。我有这个错误来自PyCharm项目。

pyrebase: v4.5.0 https://github.com/nhorvath/Pyrebase4

Answer 1

我有同样的问题，我解决了更新pip。我还在github上发现了一个类似的导入问题。

Answer 2

python -m ensurepip

python get-pip.py

pip install awscli --ignore-installed six

ModuleNotFoundError: No module named 'pyasn1_modules'

pip install pyasn1_modules

ModuleNotFoundError: No module named 'google.protobuf'

pip install protobuf
