tty terminal - UnicodeDecodeError: 'utf-8' codec can't decode byte (pudb/debugger.py in _runscript)

[bobslee]

Describe the bug When debugging from a separate terminal, upon starting the debugger the following error (and traceback) occurs.

Traceback error

Traceback (most recent call last):

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x88 in position 40: invalid start byte

To Reproduce Steps to reproduce the behavior:

1. CLI: PUDB_TTY=/dev/pts/0 pudb3 .venv/bin/python ./my-script.py
2. See error and traceback above

Expected behavior A debugger without the error.

• version of pudb: 2022.1.1

PUDB_TTY=/dev/pts/0 pudb3 .venv/bin/python ./my-script.py

What's that .venv/bin/python doing there? Pudb will try to read that like a script.

[asmeurer]

If you want to run pudb from a specific python, you should use ./venv/bin/python -m pudb my_script.py.
