ModuleNotFound skbuild

Code

I have the following error while doing this command on Linux : pip3 install cmake --upgrade.

Collecting cmake

        from skbuild import setup
    ModuleNotFoundError: No module named 'skbuild'
    
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-lgui9mlv/cmake/

How can I solve this ?

It appears as though a build dependency is missing? @jcfr

I tried to force it to different versions with
pip3 install 'cmake==3.1x.x' --upgrade

And I have this error only with the version 3.16.3, the one taken by default with --upgrade parameter.
Also, I don’t have this error on Mac, only on Debian.

Which python version are you using ?

I am using Python 3.7.3

Here is what is happening:

docker run -ti --rm debian:buster

# then from within container
apt update
apt install python3-pip
python3 -c "from pip._internal.pep425tags import get_supported; print('\n'.join('-'.join(x) for x in get_supported()))"

Until scikit-build/cmake-python-distributions#78 is addressed, you will not be able to install recent CMake wheels.

Note that building cmake using the source distributions is not something we support. I will probably look into removing the sdist (source distribution) from pypi completely.
