Python Error : No module named pkg_resources

Question

I would like to use Python3.7 on MacOS

I already Python 2.7 version.

I created an alias on .bash_profile, alias python="/usr/local/bin/python3.7" then source ~/.bash_profile.

So I deleted Python2.7 to /usr/local/lib/

Now, when I try to execute pip install PySide2, I have an error :

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 6, in <module>
    from pkg_resources import load_entry_point
ImportError: No module named pkg_resources

I think this error has happened since I deleted Python2.7

Someone can help me to resolve my error ?

Thank you !

pyinstaller 3.6 is incompatible with setuptools 45.1.0 on python 3.7.*, should be downgraded to 45.0.0

pip install setuptools==45.0.0

can also be fixed with passing/adding hidden_imports 'pkg_resources.py2_warn' to pyinstaller spec

Issue and solutions are tracked here: https://github.com/pypa/setuptools/issues/1963

setuptools version **45.0.0** causes some problem while using PyInstaller. Using sersion **44.0.0** will be better in that case – Shahriar Rahman Zahin Mar 29 '20 at 06:50

I found solution from here.

In my case, I open hook-pkg_resources.py file from the following directory:
```
~/.local/lib/python3.6/site-packages/PyInstaller/hooks/
```

After that I added this line of code:

hiddenimports.append('pkg_resources.py2_warn')

between these two lines of code:

hiddenimports = collect_submodules('pkg_resources._vendor')

and

excludedimports = ['__main__']

After that, I ran PyInstaller again and the resulted executable worked like charm.

This is caused because of a broken setuptools package, you just need to reinstall it.

For most operating systems: pip install setuptools

Linux: apt-get install python-setuptools or yum install python-setuptools
