############################

############################
|
|
Python recognizes {importable!r} as an importable package[^1],
|
|
but it is absent from setuptools' `packages` configuration.
|
|
|
|
This leads to an ambiguous overall configuration. If you want to distribute this
|
|
package, please make sure that {importable!r} is explicitly added
|
|
to the `packages` configuration field.
|
|
|
|
Alternatively, you can also rely on setuptools' discovery methods
|
|
(for example by using `find_namespace_packages(...)`/`find_namespace:`
|
|
instead of `find_packages(...)`/`find:`).
|
|
|
|
You can read more about "package discovery" on setuptools documentation page:
|
|
|
|
- https://setuptools.pypa.io/en/latest/userguide/package_discovery.html
|
|
|
|
If you don't want {importable!r} to be distributed and are
|
|
already explicitly excluding {importable!r} via
|
|
`find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`,
|
|
you can try to use `exclude_package_data`, or `include-package-data=False` in
|
|
combination with a more fine grained `package-data` configuration.
|
|
|
|
You can read more about "package data files" on setuptools documentation page:
|
|
|
|
- https://setuptools.pypa.io/en/latest/userguide/datafiles.html
|
|
|
|
|
|
[^1]: For Python, any directory (with suitable naming) can be imported,
|
|
even if it does not contain any `.py` files.
|
|
On the other hand, currently there is no concept of package data
|
|
directory, all directories are treated like packages.
