This error is from Numpy, not pip. Please report to Numpy.

I returned the py version to 3.11 to resolve, thank you

Where this error might arise from in NumPy? I tried Pandas, and SciPy using py -m pip install to install those libraries. Also: py -m pip install wheel, setuptools; then I tried something like
from setuptools import setup, find_packages
setup(name = "gusml", version = "1.0", packages = find_packages())
Also, I tried setup(name = "gusml", version = "1.0", packages = find_packages(), install_requires=["numpy"]). The commands were py setup.py build, install.
Python told me to learn about pypa/build, and pypa/install, and drew my attention to poetry. Poetry was successfully installed and I used the same command:
py -m pip install poetry
This triggered installation and failed due to CARGO; after installing CARGO, Python could install Poetry using PIP.
Another remark: I am not any skilled, but I tried py -m venv myenv and then installed all those things: setuptools, wheel, and ran pip install numpy. Same error. I went to the source code of the error contained in Lib\site-packages\pkg_resources_init_.py, and changed ImpImported to zipimporter. Nothing changed. Then I deleted the code, saving it beforehand, and tried again. Same error. This further indicates that the problem is in Numpy.

Any advice where to look out for it?

We are also running into this error trying to support python 3.12 in pipenv. https://github.com/pypa/pipenv/actions/runs/5772265760/job/15647071533

#EDIT: reportlab, pygame were successfully installed. SciPy, Pandas, Numpy were not.
#Edit2: Read numpy/numpy#22623
#Edit3: Read https://github.com/search?q=repo%3Anumpy%2Fnumpy%20Python%2012&type=code
So far: Wait until Numpy is 1.26.0 or contribute to it.
I tried Poetry: SciPy, Numpy failed:

Note: This error originates from the build backend, and is likely not a problem with poetry but with numpy (1.25.2) not supporting PEP 517 builds. You can verify this by running 'pip wheel --use-pep517 "numpy (==1.25.2)"'

So, we must run pip wheel --use-pep517 "numpy==1.25.2" and see if NumPy supports PEP 517. As the result is an error, same as above, NumPy turns out to not support the aforementioned PEP 517 (Build and Configuration of Packages without directly setup.py which is using setuptools). Thus, I must go and read NumPy code again, specifically about how it processes packages and what tools it uses. The possible issue is NumPY IS NOT COMPATIBLE with Python 12.1 version I downloaded, which is rereleased one.

Hi all, as explained above, the issue reported here is from setuptools, not pip. If you believe you are running into the same issue as in the top post, please report to setuptools instead. This is the issue tracker for pip, and posting here will not help with your issue in any way. The setuptools issue tracker can be found at https://github.com/pypa/setuptools/issues.

@matteius This is a different issue, tracked in #11501 and has been fixed in pip 23.2. Please open a new issue if you believe there has been a regression.
