Cannot build wheels when trying to install Manim

I am trying to install manim on my PC. Every time I try to use
choco install manim
It says that manim is already installed!
When I try to then use pip install... it comes up with:
ERROR: Could not build wheels for manimpango, mapbox-earcut, pycairo, which is required to install pyproject.toml-based projects
Any help with how to fix this would be greatly appreciated!

What does Failed building wheel for Pillow mean?

I don't understand what this error 'Failed building wheel for Pillow' means?
I just wanted to install easyocr, but it gives me an error, I tried to find a solution to the problem on the Internet but could not find it. Help me solve this problem, I will be very grateful
pip install easyocr

Try doing pip install -U pip
This will upgrade the version of pip in your system. Sometimes, the latest version of a python package that you are trying to install is not compatible with the pip version installed in the system.
The above command will update your pip and once that is done, you can try running the command pip install easyocr once again.
Let me know if this helped!!
If this did not help, please let me know whether you are on a windows machine or a linux machine.
If you are on an Ubuntu machine then you probably have to redo the steps that I mentioned using pip3 instead of pip.

unable to download OpenCv on mac with pycharm

Don't know what the issue is. I am unable to download openCv on my mac with pycharm.
I use Python Version 3.8.1.
I have tried to:
pip3 install --upgrade pip setuptools wheel
pip3 install --upgrade pip
I use command:
pip3 install opencv-python
Still does not work. I get the message:
ERROR: Failed building wheel for opencv-python
Failed to build opencv-python
What is the issue? Hope you can help. Has been taking me several of hours now and each time to "build" takes like 1 hour..

Do you have a MacBook with M1 processor?
The problem is that pip does not always install the arm64 version and instead tries to use rosetta to run amd64 versions which breaks. So it “works” it is just finicky and error prone.
Try to install following the steps on this blog: https://blog.roboflow.com/m1-opencv/

ERROR: Could not build wheels for Kivy which use PEP 517 and cannot be installed directly

I've been trying to install kivy on windows10 machine and I did not get an expected output, instead, I got a series of weird error messages. First I ran the following commands:
python -m pip install --upgrade pip wheel setuptools
python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew
python -m pip install kivy.deps.gstreamer
python -m pip install kivy.deps.angle
python -m pip install pygame
And as far as I know, everything went right.
After that, I ran this command: python -m pip install https://github.com/kivy/kivy/archive/master.zip
Command output helped me break down the process of executing it.
First I got an error message while "Getting requirements to build wheel".
error message:
I got this error while "Preparing wheel metadata" and "Building wheel for Kivy (PEP 517)" as well. I think that it is worth mentioning that every time I said that error occurred, it occurred twice, one after another.
After that, I got a huge error:
You can download the test file with an error message on this link: https://filesend.standardnotes.org/send/BPQTjNM3aiUyRXOtfA3A#ZGI2ZDUzMWU2MmYzNTlhNTVlODEw
Note: All the commands that I executed were executed in cmd ran by the administrator.
If anyone can explain to me what is going on I would highly appreciate it!

Going by related issues here - ERROR: Could not build wheels for pendulum which use PEP 517 and cannot be installed directly and pip failing to build wheels for scipy
The answers seem to suggest that downgrading pip version will likely solve the problem. But before that please try
pip install --upgrade pip setuptools wheel
Instead of
python -m pip install --upgrade pip wheel setuptools
and see if it solves. If not, downgrade your pip by doing
python -m pip install --force-reinstall pip==18.1
If none of these work then your only viable solution is to use Kivy within Anaconda. You can see more on installation from here.

If I am not mistaken, this error means that you are trying to run 64-bit application on a 32-bit system. Install python version which corresponds to your OS, and then try again.
Also, make sure you have the newest version of C++ Redistributable installed.

Not able to install skbuild

I am trying to install "CMake" with command
pip3 install CMake.
Its gives an error for a module "skbuild"
from skbuild import setup, ModuleNotFoundError: No module named 'skbuild'
But but when tried to install skbuild with command
pip3 install skbuild
it gives error
"Could not find a version that satisfies the requirement skbuild (from versions: ) No matching distribution found for skbuild".
I am not able to solve this error. Please help. I trying the implementation it on Window 10. Using Python 3.7.0. I tried couple of versions of pip3 (10.0.1, 9.0.3, 9.0.2, 9.0.1). Nothing is working.

Try pip install scikit-build. For me, pip install cmake works properly afterwards.

this worked for me while installation of this github repo https://github.com/ultralytics/yolov3
# For pip
pip install scikit-build
# For pip3
pip3 install scikit-build
