@danpalmer add `--upgrade-pip --preinstall "setuptools>=38" --preinstall "wheel"` to isolate against smelly or incomplete environments.

Situation regarding relevant options: ```console $ virtualenv --help … --setuptools DEPRECATED. Retained only for backward compatibility. This option has no effect. --distribute DEPRECATED. Retained only for backward compatibility. This option...

The ultimate quick-fix solution is to *remove* `--setuptools` from your rules if you encounter the error (removing it from dh-venv code would break OLD virtualenv versions) – add that to...

A quick way to do this would be to provide a helper script, and refer to it in a "how-to" section of the docs.

BTW, given manylinux1/2010 this is less of an issue, or put another way is only relevant when you build wheels yourself (or pip does for you). It is still legit...

Remove the CRs you have in your files (dos2unix).

3 has all the things. just actually look at the files, using the Debian docs for understanding stuff.

Please do not tack on new problems to existing issues – open your own.

FYI, I solved this on Win10 / WSL1 by `.venv/bin/npm install vega-lite vega-cli canvas` into a mixed Python/Node virtualenv.
