Python脚本在pm2中抛出模块未找到错误但在cmd中有效

Question

I want to demonise a python script with pm2 that worked before. I've created a venv with Python 3.6.8. I installed all modules that are required and tryed the script via console, which works. But if I start the module via pm2, I get an ModuleNotFound Error:

For all the other 23 scripts it worked as well with pm2. The venv Python version is 3.6.8, the same as the version from the other venv where it was running before.

Has someone encountered similar behaviour and can give me some suggestions on what I could try to solve the issue? Reinstalling the module doesn't help.

Answer 1

You should specified the absolute path of your virtual environment

pm2 start 18 --interpreter /path/to/your/.venv/bin/python3

Also remember to check whether is the package exists:

/path/to/your/.venv/bin/python3 -m pip list
