[Iverilog-devel] GitHub actions vs. python and docopt

[Stephen W. <st...@ic...>]

I need Windows help with running a python3 script in github Actions
(CI). I'm working on a new regiression test script written in python,
and it uses docopt. That works perfectly fine in Linux and MacOS on
GitHub actions, but I can't figure out how to get it to work on the
Windows targets:

I put a "pip3 install docopt" before the tests, and the action is reporting:

```
Run pip3 install docopt
Collecting docopt
Downloading docopt-0.6.2.tar.gz (25 kB)

Successfully built docopt
Installing collected packages: docopt
Successfully installed docopt-0.6.2
```

... and that's great, but later, when the action runs the python script, I get:
```
Traceback (most recent call last):
File "D:\a\iverilog\iverilog\ivtest\vvp_reg.py", line 14, in <module>
from docopt import docopt
ModuleNotFoundError: No module named 'docopt'
```

Github actions are using msys2 here. The PR that I'm working on is here:

Any ideas?
