A Problem With Aliases

[erasmos-hmrc]

I installed the recommended version of Python (3.8).

On my system (MacOS), the binary was python3. However, I aliased it (via .zshrc) to python.

However, whenever I ran an sm command, I would get something like the following:

Traceback (most recent call last):
  File "/Users/seanrasmussen/.local/bin/sm", line 182, in <module>
    _process_command()

FileNotFoundError: [Errno 2] No such file or directory: 'python'

After various attempts, I found that changing this line to use the shell worked:

   proc = subprocess.Popen(["python", "--version"],
                          shell=True,

Note that I'm not using pyenv as recommended.

Actually, I had to update the shell to be 'True' in all three places to make it work.
