Hi there,

That sounds like a cool endeavor.  I believe you should be able to remove the 
portion of python-awips that is 
trying to use the 'pwd' package.

Find the WsId.py package here:
"C:\Users\Me\PycharmProjects\Playground\.venv\Lib\site-packages\dynamicserialize\dstypes\com\raytheon\uf\common\message\WsId.py"

Open it with a text editor and modify the following:

1. Comment or delete line 40:
#import pwd
2. Comment or delete lines 51 and 52:
#    if userName is None:
#       self.userName = pwd.getpwuid(os.getuid()).pw_name

Try re-running your python code and let me know if that gets you beyond the 
previous failing point?
Thanks!
