### Problem Previously, cookiecutter-generated projects didn't install dependencies during `pip install <package-name>`. ### Solution Check whether the following section exists in `pyproject.toml`. ``` [project] name = "<package-name>" dynamic=['version', 'dependencies'] ... [tool.setuptools.dynamic] dependencies = {file = ["requirements/run.txt"]} ``` For more info: https://github.com/diffpy/diffpy.structure/pull/98
