I have tried updating setuptools, pip, and wheel. I have tried a lot of things but i just can't wrap my head around why it is causing this error. I am using the latest pip version and using the latest python version. Im also using the latest setuptools version and the latest wheel version. Sorry i am trying to make my question not mostly code so i can actually post it lol.

This can help you #Thomas.
I had the same issue, this solved my problem and install successfully.
Due to pythonnet version mismatch python 3.10.1 reported this error.
Go to: https://pypi.org/project/pythonnet/
Then Follow these steps:
Open the official website ：pythonnet.
Click on the "Download files".
Then download "pythonnet-2.5.2-cp38-cp38-win_amd64.whl" (for 64-bit python version)
Modify file name like this:
Before: pythonnet-2.5.2-cp38-cp38-win_amd64.whl
After: pythonnet-2.5.2-cp310-none-any.whl
And now try to install like: pip install path of the file
ex: pip install C:\users\user5\desktop\pythonnet-2.5.2-cp310-none-any.whl
I hope this help you. All the best.

dlib not installing pycharm, how to fix? No other posts have helped. I need to use python 3.9

I am not able to install dlib on my computer. It gives me this error, but no other posts have helped me. I have been searching for a few hours now but to no avail. I am not familiar with the pip command, so this error does not tell me any meaningful information. Can someone who is more experienced please tell me why this is not working? I have already tried reinstalling Microsoft Visual Studio C++ 2015, but that did not work. Installing CMake did not work either. Can someone please help me fix this?

WARNING: You are using pip version 21.1.2; however, version 21.3.1 is available.
You should consider upgrading via the 'C:\Users\danie\Desktop\pythonProject\venv\Scripts\python.exe -m pip install --upgrade pip' command.

download cmake executable file on your pc, install it and install cmake build tools for c++ from visual studio build tools. After installing cmake with visual studio build tools, you need to download dlib wheel file from this github repo: https://github.com/Tobyyosoba777/Computer-Vision-OpenCv-Python-/tree/main/Libraries
download: dlib-19.22.99-cp39-cp39-win_amd64.whl
and download: dlib-19.22.99.win-amd64-py3.9.exe
install the .exe file on your pc, restart it(not necessary) and open the current directory of the downloaded .whl file where it is saved on your pc in your python/anaconda terminal/ cmd
for example:
C:\Users\USER->cd desktop "if you downloaded the file to your desktop" this command will move you to the current directory of the .whl file
then input: "pip install dlib-19.22.99-cp39-cp39-win_amd64.whl"
that should work

It worked after I installed all of the visual studio build things (all 80 gb)
Just for anyone coming to this in the future

Getting Error while installing dlib (Python)

I have already installed VS and CMake but still, I am unable to install dlib.
Following error triggers while executing the command on CMD (pip install dlib) I have tried two versions, dlib and dlib==19.18.0.
I have tried many different solutions but still stuck, also tried to uninstall everything including VS and reinstalling it but this didn't help me.

Installing pythonnet with no internet access

I am trying to install pythonnet on a machine with no internet access. On a connected machine I downloaded pythonnet-master.zip from Github, and pythonnet-2.4.0.tar.gz from pypi.
When I try pip install pythonnet-2.4.0.tar.gz, I get the error The remote name could not be resolved: 'www.nuget.org.
I then used conda install nuget-3.2.0.10516-py34_0.tar.bz2 to take care of nuget. The installation was successful, but I still cannot install pythonnet.
My attempts using pythonnet-master.zip and conda install also failed. Any ideas would be helpful.
Here is the full error output:

heck the logs for full command output.

The setup.py of pythonnet is trying to run nugget.exe update --self which fails in you system because of the missing internet connection. I can think of two possible solutions:
Instead of a source install, try to download the right whl file. On pypi, there are only ones for cp37 and below. If you are running pyhton 3.8, you can find the right wheel file here
Extract the tar.gz archive and comment line 424: subprocess.check_call(cmd, shell=use_shell). Then run python setup.py install. This will prevent setup from trying to update nugget during the installation process

Pip error: option --single-version-externally-managed not recognized

I try to install pythonnet and got an errer, how can I fix that??
p.s the Microsoft.CSharp.Core.targets does not exist from the beginning
so I copy form "https://referencesource.microsoft.com/#MSBuildFiles/C/ProgramFiles(x86)/MSBuild/14.0/bin_/amd64/Microsoft.CSharp.Core.targets,4b2d25f00a74b6f8" myself.

I had this problem too. I was using the newest python to date, v3.9.5. From reading the Pyton.NET docs # http://pythonnet.github.io/, I found that "Python.NET is currently compatible and tested with Python releases 2.7 and 3.5-3.8". I downloaded and installed the latest 3.8 version of Python for Windows (3.8.10 to date). I updated my path to use Python 3.8 (# C:\Users\user\AppData\Local\Programs\Python\Python38 on my computer). After that I was able to install Python.NET from cmd with:
python -m pip install pythonnet
