Editable package command line interface installation under windows

Issue

Under Ubuntu I’m totally happy with my current setup. However under Windows I regularly run into issues w.r.t. this. I’m not sure if this is an issue or related to undocumented instructions.

On Windows 10 I’m running Python 3.8.6. My project.toml looks like follows:

[virtualenvs]
in-project = true

My setup.py looks like follows:

from setuptools import find_packages, setup

import my-package

setup(
   ...
   entry_points={"console_scripts": [my-cli=my_package.cli:main]},
   ...
)
...

The project structure looks as follows:

my-package
  .venv (contains virtual env)
  my_package (contains production code)
  setup.py
  poetry.toml
  ...

On windows if I install a new venv which implicitly installs the package in an editable manner via poetry install and without activating the venv (no execution of poetry shell) I can run python; >>>import my_package; >>>help(my_package) and get the expected help output. It seems like the package is installed into the system level Python installation instead of into the venv Python installation. If I try to run the CLI in the activated venv (poetry shell) my-cli --help the executable is not found. However if I try to run the CLI in the activated venv the CLI executable is not found as well.

What’s the recommended way to handle my setup under Windows properly?

You can refer to https://github.com/python-poetry/poetry-core/tree/master/tests/masonry/builders/fixtures/extended_with_no_setup for an example. Your build.py should be defined to handle building etc.

A real-world example is https://github.com/sdispater/pendulum/blob/master/build.py.

@abn I’ve tried on another windows machine with poetry run my-cli --help and got ImportError: C extension: tzutc not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace --force' to build the C extensions first. . What to do here?
