Pythonkeyerror solves the _ warn_unsafe_extraction problem in Python.

Pythonkeyerror solves the _ warn_unsafe_extraction problem in Python.

When running the "AttributeError: ResourceManager instance has no attribute '_ warn_unsafe_extraction'" Problem in the Python project, I studied it and found that it was a problem of setuptools in MacOS (SEE ), I encountered a problem with the pymongo library. I need to delete pymongo, downgrade setuptools, and reinstall it.

Solution:

1. Delete pymongo:

sudo easy_install -mxN pmongo

2. Downgrade setuptools:

sudo easy_install -mxN setuptoolssudo easy_install "setuptools<0.7"

3. reinstall pymongo:

sudo easy_install pymongo

Solve the problem !!!!!
