For instance, installing in a virtualenv with only `python3` in the `bin` folder and `python3.8` not in `PATH` fails with the following output:
```
[...]

    ----------------------------------------
```

Creating a symlink `venv/bin/python3.8` pointing to `venv/bin/python3` worked around the problem.

This appears to be caused by heuristics used to determine the `python` command around this line:

Passing the absolute path of the interpreter ([`sys.executable`](https://docs.python.org/3.8/library/sys.html#sys.executable))  would probably be more robust.
