SyntaxError: Non-UTF-8 error when running python scripts on Mac

[toprakfirat]

What's going wrong?

My project file:

module.exports = { apps: [

{
  name: 'asd',
  script: 'python3 asd.py',
  watch: true,
  cron_restart: '30 * * * *', 
  interpreter: "/Users/user/miniconda3/envs/asd/bin/python3"
},

], };

I am trying to run a python script but I get the following error:

19|getStre | SyntaxError: Non-UTF-8 code starting with '\xcf' in file /opt/homebrew/bin/bash on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details 19|getStre | File "/opt/homebrew/bin/bash", line 1 19|getStre | SyntaxError: Non-UTF-8 code starting with '\xcf' in file /opt/homebrew/bin/bash on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details 19|getStre | File "/opt/homebrew/bin/bash", line 1 19|getStre | SyntaxError: Non-UTF-8 code starting with '\xcf' in file /opt/homebrew/bin/bash on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details 19|getStre | File "/opt/homebrew/bin/bash", line 1 19|getStre | SyntaxError: Non-UTF-8 code starting with '\xcf' in file /opt/homebrew/bin/bash on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details 19|getStre | File "/opt/homebrew/bin/bash", line 1 19|getStre | SyntaxError: Non-UTF-8 code starting with '\xcf' in file /opt/homebrew/bin/bash on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details 19|getStre | File "/opt/homebrew/bin/bash", line 1 19|getStre | SyntaxError: Non-UTF-8 code starting with '\xcf' in file /opt/homebrew/bin/bash on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details 19|getStre | File "/opt/homebrew/bin/bash", line 1 19|getStre | SyntaxError: Non-UTF-8 code starting with '\xcf' in file /opt/homebrew/bin/bash on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details 19|getStre | File "/opt/homebrew/bin/bash", line 1 19|getStre | SyntaxError: Non-UTF-8 code starting with '\xcf' in file /opt/homebrew/bin/bash on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

If I delete the interpreter parameter and just use the default one, or if I just run it as:

pm2 start asd.py, I get the error and the output for a couple times:

How could we reproduce this issue?

The python script is just print("helloworld")

Same here on AWS EC2 (Linux/Ubuntu) with '\xef' character and MacOS with '\xca'. Moreover, I'm trying with poetry, everything works well when running manually the script with poetry or python itself.

Hello, have you found the solution? Can you share?

Thanks in advance!!

I stumbled across a similar kind of error but my startup script was in bash. I think it should be { ..., script: 'asd.py', ... } i.e. without python
