Python on MacOS “dyld: Library not loaded” - error

问题

I am trying to run a python script that executes few API calls and Kafka logic but getting following error:
dyld: Library not loaded: @executable_path/../.Python

Tried brew update && brew upgrade and also with both Python2 and Python3 but still getting same error.
What could be the cause and how to fix it?

回答1:

Hi I got this issue too after brew upgrade, I solved with delete virtualenv

find myvirtualenv -type l -delete

then recreate virtualenv

virtualenv myvirtualenv

回答2:

The issue is related to hombrew Python installs/upgrade.

Anyone who is using pipenv (and you should!) can simply use these two commands — without having the venv activated:

rm -rf `pipenv --venv` # remove the broken venv
pipenv install --dev   # reinstall the venv from pipfile
