pip install -e . equivalent?

We cannot run pip install -e . because there is no setup.py. What would be the way to achieve this using poetry?

I don't know how you develop, but I never need pip install -e .. I either upload my packages to PyPI or a private index, or I install from a git repository

Ugh, that is not developing, that is installing a finished package.

These are roughly equivalent, in your src dir:

pip install -e . python setup.py develop

It’s called “installing a package in development mode”. They are the starting point of beginning development. If you are not familiar with that, then I honestly do not understand how you do development.

I know two ways of doing development without it:

export PYTHONPATH=<directory-to-your-package-module> or in your code: import sys sys.path.append(…)

Are you recommending this? (I hope not)

Another use case is when you’re trying to fix something in a library used by your project. From your project’s virtualenv, you run pip install -e path/to/library so that every change you make in the library repo is directly picked up in your project where you are testing the results.
