When trying to install cookiecutter in a virtualenv with python 3.8 I keep coming up against the following error. I get the same error when trying to install jinja2 or markupsafe directly. It seems that cookiecutter is dependent on jinja2 which is dependent on markupsafe.

After having tried setting the version manually of markupsafe to 1.1.1 as suggested here[1] I ended up solving (getting around) the issue by installing version 2 of markupsafe.
It seems that jinja2 requires a minimum of version 2 and that althoough there seems to be an issue with the most up to date version of markupsafe, version 2 installs correctly.
pip install markupsafe==2
