Thanks for the report! According to pypa/pip#6256, that error message referencing PEP 517 simply means that the wheel failed to build - the actual cause is probably somewhere else in the output. Any chance you could include more of the log?

Here's the more complete context, if you want me to increase verbosity or something just tell me how.

Also, if you want to know my environment, just let me know what you want. I do have Rosetta installed, which I (only) use for two Python apps (zim wiki and pytype).

Thanks! I took a look at the code triggering the SKBuildError (https://github.com/scikit-build/scikit-build/blob/a7c746ae47d27b641f5734103e8fa4aaaabc09e3/skbuild/cmaker.py#L78-L82):

try:
    version_string = subprocess.check_output([cmake_executable, '--version'])
except (OSError, subprocess.CalledProcessError):
    raise SKBuildError(
        "Problem with the CMake installation, aborting build. CMake executable is %s" % cmake_executable)

It would appear that ninja installation is failing when attempting to run cmake --version.

• Are you able to manually run cmake --version? If not, perhaps you need to install or upgrade cmake.
• Can you run pip install ninja? I'm curious whether installing ninja always fails or only when it's a pytype dep.

(Apologies I can't do any of this troubleshooting myself; I and the other pytype devs are all on Linux ^^;)

[reagle]

Thanks! cmake was not available in my path and did not appear to be installed (brew or cask) with either architecture of homebrew. Even so, when using Rosetta2/x86_6 pytype did install...?

Fortunately, installing the brew of cmake with arch --arm64 homebrew does the trick for building an M1 version of pytype via the arm64 python/pip.

This issue could be closed, but referenced in a follow-up as a dependency issue.

Great, glad you were able to figure it out! I'll add a note to the Installation section of the README with a link to this bug.
