when deploying the project on Vercel, an error occurs:

File "/var/task/api/main.py", line 2, in <module>
from config import app, db
ModuleNotFoundError: No module named 'config'

i have 3 *.py files in my api folder

|api
   |-main.py
   |-config.py
   |-models.py

main.py has imports from config.py and models.py. I added vercel.json from the example

{
  "rewrites": [
    { "source": "/(.*)", "destination": "/api/main" }
  ]
}

But I don't understand how to properly specify the path to my modules so that main.py knows how to get them

  • I don't know how it works in vercel but in normal system it needs to add /api to PYTHONPATH. But your error shows File /var/task/api/main.py, not File /api/main.py and maybe this is problem - maybe you should add /var/task/api or /var/task/api/main Commented Aug 24 at 20:36
  • when I look at documentation for rewrites then it looks for me like it is for rewriting ULRs used to load web pages, not for foldes/paths used by Python to import modules. Commented Aug 24 at 20:42

    you could check what folders you have in print( sys.path ). it also allows to append some folders before importing. ie. sys.path.append( "/var/task/api" ) Commented Aug 24 at 20:45
