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?

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

Installing dlib with python 3.8 windows 10 error

I cant install dlib on python with cmd , I have downloaded cmake and putted it on PATH, or is there any plugin i have to download it first ? Or does my pip's environment is located at a wrong place ? Or do I have to change my python to 64 bit instead of 32 bit ? If I have to do so , please let me know the way to do it , I am a newbie

Please help me thank you !

NOTE:First make sure you have installed c++ compilers and cmake Then start following the sptes:
go to dlib on github
click on clone or download button and then download the package manually by clicking on the zip download And after the download finished , extract the file and put it in desktop
3.Then open Powershell or cmd
4.type in the command cd C:/users/(your username)/Desktop/master-dlib/master-dlib
5.Then when you changed your current working directory then type in the command python setup.py install
NOTE2: This is the manual way but also look into This Too.

go to python.org copy link location of latest binary executable or binary specific to your python version .
in cmd prompt typepython -m pip install +paste link location.
now run your .py file having dlib .

I did install Python 64 bit, Any idea what can be the problem? Why I'm still getting this error?

Dlib is support with python 3.6 to 3.7.0 version s.Try to install the dlib in anaconda prompt by following command.,
step 1:
conda create -n env_name python=3.7.0
step 2:
conda activate env_name
step 3:
conda install -c conda-forge dlib=19.17
-c is stands for channel, conda-forge is one of channels.
you can find all supported packages for conda's in this link https://repo.anaconda.com/pkgs/main/win-64/
Anaconda is available from, https://www.anaconda.com/distribution/#download-section
conda instruction are, https://docs.conda.io/projects/conda/en/4.6.0/_downloads/52a95608c49671267e40c689e0bc00ca/conda-cheatsheet.pdf

bad: impossible to install Dlib using pip

I have a big problem with dlib installation every time I try pip install dlib it gives me this huge error. I tried downloading packages upgrading system visual studio 2019 or c++ for cmake.
My operating system is Windows 7 64bit and I use Python 3.7.
