ImportError: python-dotenv is not installed, run pip install pydantic[dotenv]

Hey.

I'm having an weird issue with manage-fastapi. I installed all the needed packages using poetry:

pyprocject.toml file

[tool.poetry]
name = "ossah"
version = "0.1.0"
description = ""

[tool.poetry.dependencies]
python = "^3.7"
fastapi = "^0.68.1"
pydantic = {extras = ["dotenv"], version = "^1.8.2"}

[tool.poetry.dev-dependencies]
pytest = "^5.2"
pytest-cov = "^2.10.1"

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

After the command fastapi run I got this error message:

  module = importlib.import_module(module_str)

AFAICT dotenv is included in the pyproject.toml alongside with pydantic, could this be a poetry issue?

@arkryonia Can you run:

poetry shell
poetry install

And check if you have the issue?

It should be an environment issue.

Unfortunetly change poetry with pip gave the same issue. Before opening this issue, I checked it.

It should be an environment issue.

It was the basic things I did. And I did it again without success.

I decided to send my screen captures. So all doubt will be raised.

Screen Capture 1

Screen Capture 2

Voilà!

Hey all.

I fix the issue by installing python-dotenv using apt get install on my Debian.

Thanks

Glad it worked! @arkryonia

Thanks for closing the issue! 😄
