First step (login, backend not start)

[joCoutu]

Hello I'm new user.

# What I did:
pip install cookiecutter
cookiecutter https://github.com/tiangolo/full-stack-fastapi-postgresql
docker-compose up -d

# The backend was not started and not able to login 
# It was missing some dev dependency

# work around
vim  myproject/backend/backend.dockerfile
        # Allow installing dev dependencies to run tests
        RUN bash -c "poetry install --no-root"

What dev dependency was it missing?

[joCoutu]

No module named 'tenacity'

How did you eventually solve this? @joCoutu

Facing same issue, I tried RUN bash -c "poetry install --no-root" but still getting the following error:

File "/app/app/backend_pre_start.py", line 3, in <module>

from tenacity import after_log, before_log, retry, stop_after_attempt, wait_fixed

ModuleNotFoundError: No module named 'tenacity'

I upgraded to Python 3.8 and it started working for me. Needed changes in /backend/backend.dockerfile, /backend/celeryworker.dockerfile and /backend/app/pyproject.toml from 3.7 to 3.8

Can confirm @maneeshkm's fix worked for me

Fix solution:

Add code below in dockerFile. It works for me in Python3.8

ENTRYPOINT ["poetry", "run"]
