pycocotools - "Microsoft Visual C++ 14.0 or greater is required" although installed

I want to install the TensorFlow object detection API, for that, I need the pycocotools package, which is reliant on Visual Studio C++ Build Tools v14 or higher.
I have both tried to install the full Visual Studio 2022, as well as the Visual Studio build tools 2019 separately. No matter what I do, this is my error message:

ERROR: Failed building wheel for pycocotools
I am on a Windows 11 machine with Anaconda3 2021.11 (Python 3.9.7 64-bit) installed.
My installation details inside Visual Studio installer look like
this.
Help is much appreciated.

I believe you are missing MSBuild. You can add it from visual studio installer.
Here is what I have installed and pycocotools installed fine.

Failed to build turbodbc

Disclaimer : Turbodc installation has problems with python version 3.8+. You will be able to install Turbodc on python 3.8+, but you'll face another error while using it (https://github.com/blue-yonder/turbodbc/issues/258). So if you want to use Turbodbc, better to stick to python version 3.7 and below. Now lets get Turbodbc installed on your machine
This is going to be a long one. Stay with me -
As the error states, firstly you need 'Microsoft Visual C++ Build Tools'. You'll get it on this page: https://visualstudio.microsoft.com/downloads/. Scroll down to 'Build Tools for Visual Studio'. Download it.
Run the installer. Select 'C++ build tools' to install. Make sure to choose 'Windows 10 (or whatever version you prefer) SDK' as well to prevent this error later - https://github.com/openssl/openssl/issues/586
After installing build tools if you try to install Turbodbc (pip install turbodbc), you'll see another error - python fatal error C1083: Cannot open include file: 'boost/locale.hpp'. Which is to say the battle is half won. To resolve this error follow the steps listed here - https://github.com/blue-yonder/turbodbc/issues/236. For your ease, I'll copy them below -
Download boost from https://www.boost.org/ (click on the "Current Release" version link, in my case "Version 1.72.0", then download the Windows zip file).
Unzip the zipfile somewhere on your PC.
In a command prompt, navigate to the boost top-level directory.
Run .\bootstrap.bat (this generates the b2 executable)
Run .\b2 (this generates the stage directory and contents, takes a few minutes to run)
Set the BOOST_ROOT env variable with something like
set BOOST_ROOT=C:\your\path\to\boost\boost_1_72_0\boost_1_72_0
Run pip install turbodbc
That's all. Turbodbc should now be installed in your machine.

Try follow

Try this,
pip install rcssmin --install-option="--without-c-extensions"
pip install rjsmin --install-option="--without-c-extensions"
pip install django-compressor --upgrade
This solution works well, but it works much slower without the c extensions.
So better solution is, Intstall C++ dependencies , size of 1.1GB

Issue Installing misaka in a Django project

I need to install misaka, but when I use pip install misaka I get an error that reads:
Command "python setup.py egg_info" failed with error code 1 in C:\Users\JHONAT~1\AppData\Local\Temp\pip-build-utm0mant\misaka\
I don't really know what to do to solve it. I've tried using pip3 instead, no change and using pip2 also. I'm currently using python 3.6.4 and Django 1.11.

My internet connection is not the fastest, right now im downloading VS2015 to see if it solves my problem, because the link provided by the log doesnt work anymore. thanks for the replies, i'll update when the download finishes

am take this way
1- install conda
with prombt of conda
install :
conda install libpython m2w64-toolchain -c msys2
2-upgrade your pip by : python -m pip install --upgrade pip
3-instal misaka : pip install misaka

From package documentation
If you’re installing from source and are using Debian or a Debian
derivative (e.g. Ubuntu) make sure build-essential, python-dev and
libffi-dev are installed.
sudo apt-get install python-setuptools python-dev build-essential
EDIT
Windows:
Your error clearly states you need to install Microsoft Visual C++ 14.0
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft
Visual C++ Build Tools":
https://go.microsoft.com/fwlink/?LinkId=691126

Working solution!
Go to https://visualstudio.microsoft.com/downloads/
scroll down one page and download Visual Studio 2017 community.
Go through following link to download the required components for Microsoft Visual C++ 14.0, the link provides what components to be selected while downloading.
https://developercommunity.visualstudio.com/content/problem/409173/error-microsoft-visual-c-140-is-required.html
Hope it works as it worked for me!

Do this:
git clone https://github.com/FSX/misaka.git
2.cd misaka
3.python setup.py install

Only working solution I found for windows,
Go to Visual Studio download page as mentioned in the error, download the installer for the latest version, run the installer,
if you already installed visual studio then click modify,
make sure to select the required packages, especially 'windows 10 sdk' as in the image [Around 1.2gb download and 4.2gb disk space needed in first install].
Then run pip install misaka, to successfully build the package.
If Anaconda distribution is installed in your system, you can try running
conda install libpython m2w64-toolchain -c msys2
like as suggested in other answers, but it won't work for all windows-python version combinations.Any time, building the package requires visual c++.

You are using pip version 7.1.0, however version 7.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' comm
and.

Here are my PYTHONPATH + PATH

Did i miss anything?
Any help in that would be great!

What you need is to have Microsoft Visual C++ 10.0 compiler (and as far as I remember version 10.0 doesn't necessarily mean Visual Studio 2010) installed on your system and vcvarsall.bat accessible from PATH environment variable.
However, it is usual for Windows to have enormous amount of blocking issues connected with compiling python extensions via pip (or it's just me?), so my usual workaround of the error you get is to google some Windows binary installers (mysql-python for 2.7 for instance) or .whl files. Both have python extensions compiled for a particular Python and architecture thus eliminating the need in having C or C++ compiler installed.
