Processing /root/parts/hello/build Preparing metadata (setup.py) ... error error: subprocess-exited-with-error × python setup.py egg_info did not run successfully. │ exit code: 1 ╰─> [14 lines of output] error: Multiple top-level packages discovered in a flat-layout: ['snap', 'empty']. To avoid accidental inclusion of unwanted files or directories, setuptools will not proceed with this build. If you are trying to create a single distribution with multiple packages on purpose, you should not rely on automatic discovery. Instead, consider the following options: 1. set up custom discovery (`find` directive with `include` or `exclude`) 2. use a `src-layout` 3. explicitly set `py_modules` or `packages` with a list of names To find more information, look for "package discovery" on setuptools docs. [end of output] note: This error originates from a subprocess, and is likely not a problem with pip. error: metadata-generation-failed × Encountered error while generating package metadata. ╰─> See above for output. note: This is an issue with the package mentioned above, not pip. hint: See above for details. Failed to build 'hello'. Recommended resolution: Check the build logs and ensure the part's configuration and sources are correct. Run the same command again with --debug to shell into the environment if you wish to introspect this failure. ``` source: https://github.com/pypa/setuptools/pull/2894
