Building wheel for numpy (pyproject.toml) ... error

I have created a python app in my namecheap cpanel. I uploaded by server files in that and also UI files in public_html. However, I was getting Internal Server Error 500. Then I contacted their customer service. They told me install joblib through terminal. I installed it. Then they said in my root folder a file named "stderr.log" it said numpy is missing. So I tried to install numpy. But it shows the following error. Even customer service person failed to provide a solution. When I try pip install numpy, it shows the following large error. Please help.

`numpy.distutils` is deprecated since NumPy 1.23.0, as a result
of the deprecation of `distutils` itself. It will be removed for
Python >= 3.12. For older Python versions it will remain present.
It is recommended to use `setuptools < 60.0` for those Python versions.

Someone know how to resolve this? I have already installed pyqt5, and I have tried basically everything, but it still doesn't work.

You may be using version 3.10 of the Python language. Pyqt5-tools works best in python 3.9. You can review "https://pypi.org/project/pyqt5-tools/" here.

I faced the same problem with having python 3.10.1 installed in my system (fedora35). This error occured both in my os and virtual environment. Later I installed python3.7 and from venv I could install scikit-learn.Try installing scikit-learn from different python version, which should work.

Same problem here.
noted that scilean only supported by python 2.7, 2.8 and 2.9.
so just downgrade python to 2.8 then reinstall scilearn.

Similar, if I try just to do pip3 install pyobjc, I get a similar trackback, ending with these fatal words:

Any hope for me, or is there, for instance, some known incompatibility with the system bundled version of Python?

I am a month late here but the first line of the error is:
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
You need to install the full version of xcode from the app store not just the command line tools. :)

ImportErrors with Python setuptools.command.sdist

I'm trying to install Newspaper, which installs a whole bunch of dependencies using pip. During the installation of a lot of its dependencies, this error is getting raised:
ImportError: <module 'setuptools.command.sdist' from '/usr/local/lib/python2.6/dist-packages/setuptools-10.0.1-py2.6.egg/setuptools/command/sdist.pyc'> has no '_default_revctrl' attribute
Installing without pip works fine, but is quite tedious due to the number of dependencies Newspaper has. Can anyone give me a hand?
Here's the full traceback for one instance of the error:

This could also be caused by a change in setuptools released today:
https://bitbucket.org/pypa/setuptools/issue/320/cannot-upgrade-to-1001

running easy_install solved it for me:
easy_install --upgrade setuptools

Upgrading setuptools with pip can solve this:
sudo pip install --upgrade setuptools
