repo2docker quits during installation of feedparser: "error in feedparser setup command: use_2to3 is invalid."

I did some research and it appears that the problem is the use of "setuptools" with a version>57.5.

But I have no clue how I can tell the script that is running to use an older version of setuptools...

There is a Workaround.

1. Clone repository:
   $ git clone https://github.com/mikhailklassen/Mining-the-Social-Web-3rd-Edition
2. Comment out (#) "feedparser=5.2.1" in Mining-the-Social-Web-3rd-Edition/binder/requirements.txt
3. Create Container from local/edited repo:
   $ repo2docker Mining-the-Social-Web-3rd-Edition
4. In the terminal of the created docker container type:
   $ pip install "setuptools<58"
   $ pip install "feedparser==5.2.1"
