I'm trying to install tweepy (and by extension oauthlib), and I'm getting the following error when attempting to install:

Collecting requests-oauthlib>=0.4.1 (from tweepy)
Using cached requests_oauthlib-0.7.0-py2.py3-none-any.whl
Collecting oauthlib>=0.6.2 (from requests-oauthlib>=0.4.1->tweepy)
  Using cached oauthlib-2.0.0.tar.gz
Complete output from command python setup.py egg_info:
Traceback (most recent call last):
  File "<string>", line 1, in <module>

    key = pkg_resources.safe_name(str(attrs['name'])).lower()
AttributeError: module 'pkg_resources' has no attribute 'safe_name'

Interestingly, the /private/var/folders/t7/751h0y1102z99ysr6659yjcr0000gn/T/pip-build-aoklhwtw/oauthlib/ folder does not exist, so I can t even delete that/look at it closer.

Any ideas what might cause this?

Found the solution. I had to upgrade setuptools, so: 

$ sudo pip3 install --upgrade setuptools

I ran into the same error while running pip inside a virtualenv environment, however setuptools were already up-to-date in my case.

What fixed it for me

# exit the virtualenv
deactivate

# re-initialize your virtual environment (your command may differ)
virtualenv --python=python3.7 env

# activate the virtualenv again
source env/bin/activate

# re-install your dependencies
pip install -r requirements.txt

Root cause

The root cause in my case was that I had accidentally deleted the pkg-resources pip package that virtualenv creates in ubuntu. Since pip install pkg-resouces fails (pkg-resources is not a real pypi package), reinitializing virtualenv is the only way to get that package back.

  • This helped to me also, however I needed to delete .venv folder before re-initialization. – Jan Tancibok Jul 08 '20 at 15:31
  • Alternatively, `pip install setuptools --force` worked for me to restore the pkg-resources I had uninstalled. For reference, [stackoverflow: No module named pkg_resources](https://stackoverflow.com/questions/7446187/no-module-named-pkg-resources) – MichaelShimniok May 29 '21 at 18:35

I had to use

pipenv --rm

Then I just reinstalled Django and it worked fine.
