🐛 Bug Report

failed to make an editable install

🔬 How To Reproduce

Steps to reproduce the behavior:

0. system-wide it's Anaconda 3.8. there exists poetry, but it's not used as shown below
1. create an project using all default settings (named python-project)
2. in the project folder, create a setup.py as follows:

from setuptools import find_packages, setup

setup(
    name="python_project",
    version='0.0.1',

    author='author',

    packages=find_packages(where='python_project'),
    package_dir={'': 'python_project'}
)

3. in system-wide python & in project folder, run pip install -e ./
4. getting error:

ERROR: Command errored out with exit status 1:
     command: 'C:\Users\xxx\anaconda3\python.exe' -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'C:\\path-to\\python-project\\setup.py'"'"'; __file__='"'"'C:\\path-to\\python-pro
ject\\setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' develop --no-deps
         cwd: C:\path-to\python-project\
    Complete output (3 lines):

5. delete pyproject.toml as well as related .pre-commit-config.yaml and .github;
6. run pip install -e ./ again and it succeeds.

📈 Expected behavior

to create an editable install by just adding a setup.py file.

📎 Additional context

For my specific project, an editable install fits better as it involves pywin32.

I found a "fix" as follows:

• comment out the build-backend = "poetry.core.masonry.api" line in pyproject.toml;
• make an editable install with pip install -e . --no-use-pep517

Be aware of how conda interacts with poetry. The solution:

Create a new conda environment using a yaml file in which you install poetry into the conda environment:
conda env create -f condaenvironment.yaml

The condaenvironment.yaml file:

name: newenv
channels:
  - https://conda.anaconda.org/conda-forge
  - defaults
dependencies:
  - python>=3.6,<3.9
  - poetry=1.1.6
  - poetry-core=1.0.4

Then activate this new environment (conda activate newenv) and run within this environment make install. Do not use the standard system-wide poetry install!

Note that I fixed the poetry & poetry-core versions as the new releases are buggy and cause an error.
