Python 模块在 macOS Catalina 更新后不工作

Question

After updating macOS to Catalina, I can no longer import modules like Pandas, Numpy or Scipy--I get a ModuleNotFoundError . Interestingly, import os and import sys do not throw this error.

Does anyone know why this is and how to fix it?

Thanks

Probably after update you have another default Python interpreter.

You either should find where "the old one" is located or install again all libraries needed (eg pip install pandas )
