I’ve found this snippet as an alternative solution. It’s a more graceful removal of libraries than remaking the virtualenv: pip freeze | xargs pip uninstall -y In case you have packages installed via VCS, you need to exclude those lines and remove the packages manually (elevated from the comments below): pip freeze | grep -v … Read more
my question differ because I ask for a human-written pyproject.toml First, the pyproject.toml file is always “human-writable“. Then, it is important to know that in this context setuptools and Poetry take the role of what are called “build back-ends” (in a “PEP 517” sense), and there are many such build back-ends available today, setuptools and … Read more
One aspect is covered here https://pip.readthedocs.io/en/stable/reference/pip_install/#vcs-support (Updated link: https://pip.pypa.io/en/stable/topics/vcs-support/) In particular, if setup.py is not in the root directory you have to specify the subdirectory where to find setup.py in the pip install command. So if your repository layout is: pkg_dir/ setup.py # setup.py for package pkg some_module.py other_dir/ some_file some_other_file You’ll need to use … Read more
Firstly, this import statement: from models import some_model should be namespaced: # in myproject/backend/backend.py or myproject/api/api.py from myproject.models import some_model Then you will need to get the directory which contains myproject, let’s call this /path/to/parent, into the sys.path list. You can do this temporarily by setting an environment variable: export PYTHONPATH=/path/to/parent Or, preferably, you can … Read more
We also develop software projects that depend on numpy, scipy and other PyPI packages. Hands down, the best tool currently available out there for managing remote installations is zc.buildout. It is very easy to use. You download a bootstrapping script from their website and distribute that with your package. You write a “local deployment” file, … Read more
Recommended approach for pytest>=7: use the pythonpath setting Recently, pytest has added a new core plugin that supports sys.path modifications via the pythonpath configuration value. The solution is thus much simpler now and doesn’t require any workarounds anymore: pyproject.toml example: [tool.pytest.ini_options] pythonpath = [ “src” ] pytest.ini example: [pytest] pythonpath = src The path entries … Read more
You can take the wheel file change the extension to .zip and then extract the contents like any other zip file. from PEP 427 A wheel is a ZIP-format archive with a specially formatted file name and the .whl extension. Example the Django python package has a wheel file. Try Django-1.8.4-py2.py3-none-any.whl as an example. Their … Read more
Try to avoid calling setup.py directly, it will not properly tell pip that you’ve installed your package. With pip install -e: For local projects, the “SomeProject.egg-info” directory is created relative to the project path. This is one advantage over just using setup.py develop, which creates the “egg-info” directly relative the current working directory. More: docs … Read more

There are many ways to import a python file, all with their pros and cons. Don’t just hastily pick the first import strategy that works for you or else you’ll have to rewrite the codebase later on when you find it doesn’t meet your needs. I’ll start out explaining the easiest example #1, then I’ll … Read more
