Fresh installs print warning due to requests vs chardet 5.0.0 incompatibility

[jepler]

• Cookiecutter version: 2.1.1
• Template project url: https://github.com/adafruit/cookiecutter-adafruit-circuitpython/
• Python version: various including 3.9
• Operating System: various including ubuntu

Description:

We test our cookiecutter with a pytest. Since the release of chardet 5.0.0, which requests 2.0.12 treats as incompatible, this produces a (caught) AssertionError and a runtime warning, both of which are treated as failures by pytest. There has been an issue opened to support chardet 5.0.0 in cookiecutter but no maintainer activity has occurred there yet: psf/requests#6177

While this has a severe impact on us (causes our Actions runs to all fail), for most users of cookiecutter this only causes the warning to be printed each time cookiecutter is run.

Most likely we'll be taking steps to ensure chardet<5 is installed during our CI process. I'm honestly not sure what would be constructive for cookiecutter to do about this, but I wanted to file this issue anyway for others who may encounter the warning, especially in a context that turns it into an error like ours does.

What I've run:

$ pip install cookiecutter
$ cookiecutter --version
/tmp/_envcc/lib/python3.9/site-packages/requests/__init__.py:109: RequestsDependencyWarning: urllib3 (1.26.9) or chardet (5.0.0)/charset_normalizer (2.0.12) doesn't match a supported version!
  warnings.warn(

'pip3 install --upgrade requests' worked for me.

[jepler]

yay! I think you're right.

'pip3 install --upgrade requests' сработало для меня.
