Cmake error: ModuleNotFoundError: No module named 'skbuild'

[armunday]

I have been troubleshooting this error for a day and a half now to no avail. Not sure what is going on. I saw a solved issue but those fixes are not working for me. Below is the error code.

I have C++ Build Tools installed, I have cmake installed and it is in my environment variables. Just have no clue what is happening

[jcfr]

It looks like you are installing the line_profiler package (either directly or indirectly by installing an other package having line_profiler as a dependency)

As we can see here, the latest version of line_profiler do not provide window wheels (file with the .whl extension).

A wheel is a convenient "archive" containing everything ready to be installed for the current platform.

Considering there are no convenient .whl file for windows, python try to build the wheel locally before installing it.

For some reason, on your platform .. it also tries to build cmake wheel from source. Which is strange because, we provide wheel for windows. See https://pypi.org/project/cmake/#files

We can see here the build time dependencies.

For convenience, here is the content of requirements/build.txt :

Cython
scikit-build
cmake
ninja

[jcfr]

What happen if you run the following:

python --version

python -m pip install cmake

[henryiii]

Can you try updating pip (should be trivial in the virtual environment, and if that doesn't work by itself, with --prefer-binary? Also try purging your cache, just in case. I see a --no-binary :all: --only-binary :none: which sounds like it is turning off all binaries.

Hey there - came across this issue myself today trying to install line_profiler. It also happens when I just try to install cmake directly as well. However, using --prefer-binary seems to resolve it.

I'm on macOS 10.15.6.

(same thing happens when installing line_profiler: --prefer-binary works)

[henryiii]

This is because of #112 , there is no binary for 3.18.2 for CMake on macOS with Python 3.

You can also set PIP_ONLY_BINARY="cmake" in your environment, or --only-binary cmake.

[henryiii]

This would be very much improved if there was a pyproject.toml file. Then you might fail due to missing system libraries, but not due to "scikit-build" missing. Currently, inside a pyproject.toml file including cmake, it is impossible to build from source, since it creates a temporary virtual environment for building with just the items listed in this file, and then when trying to build cmake, scikit-build is not available (in the new, temporary environment), so it doesn't work.

[skvark]

I would also recommend to add pyproject.toml to this project. For example, this case could have been avoided with pyproject.toml: opencv/opencv-python#387 (comment)

@skvark :

• Arm64 wheel should be available in the next 30mins or so
• we also added pyproject.toml (thanks @yoav-orca for the contribution)
• I created an issue so that we update the build system to display a warning when the wheel is built from source as this should be reported so that we can add support for distributing the corresponding wheel.

[skvark]

Thanks!

[henryiii]

This should be solved now!

(Where now might mean some time ago, or with the 3.20.2 release)
