Cannot install "mathutils" in python

I tried everything. From pip and source code. However it keeps showing error.

I tired with anaconda, with just Python, either pip install or build source package. Nothing is working.

Pip doesn't let me install pyzmail, I always get the same error no matter what I try

So I'm following along "Automate the boring stuff" by Al Sweigart. And he uses pyzmail in the book. Naturally I'm going to want to use it too in order to follow along with the book. I've tried every single thing on the internet - and it's just frustrating. Can somebody tell me how to fix this please? I just can't get this damn pyzmail module installed. I've even tried virtual environments. I get this error no matter what, it's like it's destined to be and god wants me to suffer in the cmd prompt and google for 3 hours .

This is the error. I find it really confusing.
error: metadata-generation-failed

I am not sure that it will work but that's what I found.
setuptools>=58 breaks support for use_2to3 that is why you are facing this error
Consider downgrading the setuptools to version 57.
pip install -I setuptools==57.5.0
That is the latest 57 version.
Also, you may consider not using this library.
UPDATE
As I understood, this package is abandoned and the last release was in May 2014. Downgrading the setuptools will not work. This package fails in setting up an abandoned distribute library.

Error installing pyQt5: error: metadata-generation-failed

I was tring to install PyQt5 and a get this error:

I've tried using brew install pyqt and installing pyqt6 went out just fine. What's wrong.

Ok, I faced this issue with python 3.10.4 and after searching I found two solutions for this problem because this problem not being only with turtle but for other libraries.
#Note: These solutions for downloading any library if you have a problem mentioned above and this problem faced me in windows CMD.
So you could try this way:
pip install <libraryName>==0.0.1
0.0.1 This is the last version of the library so you should find the version of the library that you want to install for this purpose, you can find the version of the library using this command:
pip show module <name_of_the_library>
another solution that could work is using --use-deprecated=backtrack-on-build-failures
Example:
pip install turtle --use-deprecated=backtrack-on-build-failures
Hope to help you.

Cannot Install PyAudio, portaudiomodule error

Currently trying to install PyAudio on my Surface Pro 7, and am getting this error code when I try to use the prompt pip install PyAudio to install it:
ERROR: Command errored out with exit status 1:
src/_portaudiomodule.c: note: see previous definition of 'MS_WIN64'
src/_portaudiomodule.c(29): fatal error C1083: Cannot open include file: 'portaudio.h': No such file or directory
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\BuildTools\\VC\\Tools\\MSVC\\14.28.29333\\bin\\HostX86\\x64\\cl.exe' failed with exit code 2
Can someone help explain why this won't work, please? Thanks!

Download a wheel file from https://www.lfd.uci.edu/~gohlke/pythonlibs/ and install via pip install wheelfile.whl. Check your python version before downloading.

This issue means that the PyAudio library has a script with an include statement for the portaudio header file. Include statements in C and similar languages are like Import statements in Python. Because the file doesn't exist, the library can't run.
If PyAudio is installed via pip, PortAudio has to be downloaded separately. Here is the official website with instructions to download.
An alternative would be to use Anaconda to install packages for python. Anaconda will automatically install portaudio, or provide a reason why it can't, in which case, you will have to follow the steps on the website linked earlier.
