maingopy is Not Installable Using Poetry Due to Non-Compliance with PEP 517

When attempting to install the maingopy package (version 0.8.1) using Poetry, the installation fails due to an issue related to PEP 517 compliance. The error message indicates that the build process for maingopy is not successful because it requires the skbuild module, which is not present, leading to a ModuleNotFoundError. This issue occurs during the get_requires_for_build_wheel step in the build process, which is managed by the backend specified in the package's pyproject.toml.

Steps to Reproduce:

1. Run the command poetry add maingopy.
2. Poetry attempts to resolve dependencies and install the package.
3. The installation fails with the following error message:

Using version ^0.8.1 for maingopy

Updating dependencies

  ImportError: Error during setup of maingopy: maingopy requires scikit-build, which is not available.

Analysis:

The error originates from the build backend during the installation process, indicating that maingopy version 0.8.1 is not fully compliant with PEP 517, which is the standard interface for building Python packages. The specific issue is that the package depends on scikit-build, which is not available or specified properly in the build dependencies, causing the installation to fail.

This issue is not directly related to Poetry but rather to how maingopy is packaged. A temporary workaround could be to ensure that scikit-build is manually installed in the environment before attempting to install maingopy. However, the root cause needs to be addressed within the maingopy package itself to fully comply with PEP 517.

Expected Behavior:

• The package should install successfully using Poetry without requiring manual intervention.
• The pyproject.toml of maingopy should correctly specify all necessary build dependencies to comply with PEP 517.
