Python flask reloader "Errno 2 No such file or directory" error when running on docker

python windows docker flask

I've encountered the same problem here and the solution for me was to remove the executable flag from the "run.py" file.

$ chmod -x run.py

The error was very similar, but in my case I'm using an Ubuntu 18.04 WSL on a Windows 10 machine.

python windows docker flask

Try to run the app as a module:

python -m flask run
