"files" is wrong when installed without "wheel" #115

In GitLab by @blueyed on Mar 17, 2020, 12:32

When "wheel" is not installed/used, installing a package will not contain "RECORD", and it falls back to reading "SOURCES.txt" (https://gitlab.com/python-devs/importlib_metadata/blob/3150ed4da9e1267d0787c6f4c1f8258a26a1dd93/importlib_metadata/__init__.py#L270), which then might result in paths not being locate()able, when a src-based setup is used:

setup(
    ...
    packages=find_packages('src'),
    package_dir={'': 'src'},
)

This is similar to https://gitlab.com/python-devs/importlib_metadata/-/issues/112, but in this case here it could use installed-files.txt from the egg-info.
