Regression in `install_cmdstan` from 0.9.77 to develop

[tillahoffmann]

Summary:

Running install_cmdstan from the develop branch raises

Traceback (most recent call last):
  File "/usr/local/bin/install_cmdstan", line 8, in <module>
    sys.exit(main())
TypeError: main() missing 1 required positional argument: 'args'

Description:

Running install_cmdstan works as expected for 0.9.77.

$ docker run --rm -it python:3.8 bash -c 'pip install cmdstanpy==0.9.77 && install_cmdstan -h'
[help message]

But it fails for the develop branch (and similarly for the 1.0.0rc2 on pypi).

$ docker run --rm -it python:3.8 bash -c 'pip install git+https://github.com/stan-dev/cmdstanpy && install_cmdstan -h'
[TypeError, see details above]

Edit: fixed a few typos.

python -m cmdstanpy.install_cmdstan -h seems to work just fine, the issue is with setup.py

[tillahoffmann]

I've had a little dig into the setup.py. Will send a patch shortly.

I think we could just add an def entry(): main(parse_cmdline_args()) and then point to that instead of main? Not sure if there is a better way to do args.

This also affects install_cxx_toolchain in the same way
