why i'm getting this error "check the logs for full command output" when i'm installing dlib?

I'm trying to install dlib on vertual studio code but the following error is displayed:
Running setup.py install for dlib ... error

Additional note: I installed cmake and tried again but nothing change.

The error is obvious from the error message you got:
You must use Visual Studio to build a python extension on windows. If
you
are getting this error it means you have not installed Visual C++. Note
that there are many flavors of Visual Studio, like Visual Studio for C#
development. You need to install Visual Studio for C++.
You need to install *Visual Studio for C++ from here and rerun the installation so that the C++ extension to Python can get built.
You can avoid that using Anaconda where the dlib package is available already compiled (but for the moment not for Python 3.9).

you can use the following method to avoid installing the "Huge" IDE (VS) or the Anaconda.
Many binaries depend on Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 for Python 3
so, please try to use the following codes to solve it
pip install --upgrade setuptools
if you are not succeed to solve this problem,
then you can try to use this link The latest supported Visual C++ downloads to install this problem

checked here a bit and saw a solution actually: https://stackoverflow.com/a/63648302/13692454
But here is new problem, I am using VS code and even if I download C++ extentions, it doesn't fix. I have no idea to what to do. How can i fix this? Thanks in advance*

Just used google colab to fix this problem. Can't find a solution for VS code...

The answer is really simple. You have to do what it says. Go to the VS installer and install VS for C++ and C#. The reason is that these modules use C code and while using Visual Studio, you have to make it so that it can compile the C++ code

For those who don't want to install the entirety of Visual Studio there is an easier way to get the required CMake tools:
Step 1: Download and run Build Tools for Visual Studio 2022 https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2019
Step 2: Go to Individual Components and select C++ CMake tools for Windows and run through the install.
Step 3: Proceed to build your python application (e.g. dlib)

Fail to install dlib on windows10

Following a YouTube video about face recognition, I installed Python 3.8.2, then CMAKE, and then dlib. The dlib failed with the following message. At first I had python 32 bits, then I removed it and installed the 64 bit version, with same problem. Any idea?
I did the same flow on a another computer, with a similar error, that was solved after installing CMake. In this case CMake is installed.
What did I miss?

Try deepface. It is OS independent.
#!pip install deepface
from deepface import DeepFace
#face verification
obj = DeepFace.verify("img1.jpg", "img2.jpg")
#face recognition
df = DeepFace.find(img_path = "img1.jpg", db_path = "C:/workspace/my_db")
Find function looks for the identity of img1.jpg in my_db folder.

I tried a lot to install pip install dlib but it always shows an error and I reinstalled cmake.
I got the error:

Do the following:
1.go to github repository of dlib package
2.click on the the green button which has written clone or download
3.Then click on Download Zip
4.after the download finished , extract the zip file and save it in desktop
NOTE: First intall CMake and then start following other steps.
5.go to dlib-master/dlib-master and copy the directory of dlib-master folder
which for you should be C:\Users\(you'r username)\Desktop\dlib-master\dlib-master, if you followed the steps.
6.Then open pwershell and type cd C:\Users\(you'r username)\Desktop\dlib-master\dlib-master
NOTE: IF you have not installed CMake properly , consider installing it , so that you can install the dlib module without any problem.
7.When you changed your current working directory by typing the above command, Then type python setup.py install
8.If you have installed cmake, then the package would install easily and flawlessly.

Here I got the error that line

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
set CMake path into environment variable (As Shown in Figure)
Installing Visual Studio build tool latest version
link: https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2017
after installing the Visual studio build tool select the package which needed and download it.
after download & installing successfully visual studio install dlib by commanding in CMD(ADMINISTRATOR) pip install dlib

I executed setup.py as #Moh Vahedi said and got following error in cmd:
You must use Visual Studio to build a python extension on windows.
If you are getting this error it means you have not installed Visual
C++. Note that there are many flavors of Visual Studio, like Visual
Studio for C# development. You need to install Visual Studio for
C++.
So I'm installing VS now :)
