WARNING: You are using pip version 19.2.3, however version 20.3.4 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
I have python2 version 2.7.18 and python version 3.9.10 installed and pip 22.1.2 from /usr/local/lib/python3.9/dist-packages/pip. I have tried uninstalling and reinstalling Python, Wine but the error doesn't go away.

The latest PyInstaller version for Python2.7 is 3.6.
So you need to tell pip which PyInstaller version to install:

For me, it seems like the problem is somethin with the cmake command, but I have no idea what the exact problem is. I used pip install cmake and installed cmake from source, none of both worked.
Has anyone an idea how to solve this?

This may be late response but I was facing the exact same issue when trying to install dlib on visual studio code. This was my error I was receiving when trying to run the command "pip install dlib"

So my next approach was to install cmake which where the installation worked however I receive a warning that the file path to the exe was not added to my path. This resulted when running "cmake --version" to outputted in terminal
'cmake' is not recognized as an internal or external command,
operable program or batch file.
I would suspected to not run correctly, and to fix this I simply copy the path that it had printed out to my terminal after install cmake and went to
Advance System Settings -> Advanced Tab -> Environment Variables -> User Variables for 'your desktop name' open up "Path" -> click on new -> paste path
After following those steps running the command "cmake --version" correctly printed out the version install, meaning it is accessing the correct path. After that "pip install dlib" worked perfectly as proof below

I hope this may help as it is one approach that worked for me in installing dlib. As you mention your cmake is on path I would check by running the command to see if the version is correctly printing out.

Althoug trying to test every combination of the commands mentioned in my question, there apparently was one combination I didn't try:
Conda environment with python 3.6.4 and then
conda install -c conda-forge dlib
Not able to install dlib on Windows 10 and Python 3.7
As Berkay is mentioning, anaconda apparently requires python <=3.6.x, which solved it for me.
! pip install dlib would not work in this environment (probably because of another version problem with this environment) !

Cant install PyNaCl with pip inside a PyCharm venv

Using python3.8.1, installing newest version, on Windows 10:

EDIT: This only seems to be an issue in my venv (made by Pycharm) - i have no clue what the issue is, both setuptools and wheel are installed.

I ultimately solved it by using python -m pip install --no-use-pep517 pynacl

Upgrading pip within the venv worked for me:
.\env\Scripts\activate
pip install -U pip
pip install -r requirements.txt
deactivate

# for OS: Windows, package: pip, Language: python3.6 (below command is valid for only mentioned python 3.6)
pip3 install https://download.pytorch.org/whl/cu90/torch-1.1.0-cp36-cp36m-win_amd64.whl
pip3 install https://download.pytorch.org/whl/cu90/torchvision-0.3.0-cp36-cp36m-win_amd64.whl
For another version/type of the software (OS, package, Language) installed, the command must be generated from the below-mentioned link: https://pytorch.org/get-started/locally/

It is recommended to directly get the desired URL that matches system configuration from the Pytorch website-https://pytorch.org/get-started/locally/
Select the options that meet your system config and using anaconda pip install the url

Try to paste the command
pip install torch==1.7.1+cpu torchvision==0.8.2+cpu torchaudio===0.7.2 -f https://download.pytorch.org/whl/torch_stable.html
in the Anaconda Prompt. Worked for me.

The CMAKE_CXX_COMPILER:
cl
is not a full path and was not found in the PATH.
To use the NMake generator with Visual C++, cmake must be run from a shell
that can use the compiler cl from the command line. This environment is
unable to invoke the cl compiler. To fix this problem, run cmake from the
Visual Studio Command Prompt (vcvarsall.bat).
Tell CMake where to find the compiler by setting either the environment
variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.

What am I missing here?
I'm really baffled.

pip install https://pypi.python.org/packages/da/06/bd3e241c4eb0a662914b3b4875fc52dd176a9db0d4a2c915ac2ad8800e9e/dlib-19.7.0-cp36-cp36m-win_amd64.whl#md5=b7330a5b2d46420343fbed5df69e6a3f
Try this cmd command, it worked for me

I have followed below steps to install face_recognition (dlib):-
Re-installed Python 3.6.6 (https://www.python.org/ftp/python/3.6.6/python-3.6.6-amd64.exe).
pip3 install cmake
pip3 install dlib
pip3 install face_recognition
It worked for me.

If you have conda installed in your system then follow these steps:
conda create -n py36 python=3.6
activate py36
conda config --add channels conda-forge
conda install numpy
conda install scipy
conda install dlib

I know this question is for windows, But by chance if someone is looking for solution for this on Mac,
Try this command, worked for me
pip install https://files.pythonhosted.org/packages/05/57/e8a8caa3c89a27f80bc78da39c423e2553f482a3705adc619176a3a24b36/dlib-19.17.0.tar.gz#SHA256=92587c81b0165e933593f505fdf099dface0d0f8ec874b1d8655fc774598911f

if you have installed Visual Studio, you need to make sure that you have selected Clang tools
Also use command Prompt (cmd) and be patient when pip install dlib it will take more than 5 min to be compiled

Please follow the below steps:
install Python version you like
install cmake from https://cmake.org/download/ and add it to the path when install it
install visual studio from https://visualstudio.microsoft.com/visual-cpp-build-tools, then go to modify -> individual components -> choose the following:
(MSBuild/MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.27)/C++ 2019 Redistributable Update/C++ CMake tools for Windows/C++/CLI support for v142 build tools (14.27)/C++ Clang-cl for v142 build tools (x64/x86)/C++ Clang Compiler for Windows (10.0.0)/Windows Universal CRT SDK/MSVC v140 - VS 2015 C++ build tools (v14.00)/Windows 10 SDK (10.0.19041.0)/C++ 2019 Redistributable MSMs))
open the visual studio and create new project as cmake c++
you will be prompt to update the windows 10 sdk after building the project
install updates for SDK
go to windows terminal
pip install dlib
this works perfectly for me.
Thanks

The error is telling you the answer. The CMAKE_C_COMPILER:
cl
is not a full path and was not found in the PATH.
To use the NMake generator with Visual C++, cmake must be run from a shell
that can use the compiler cl from the command line. This environment is
unable to invoke the cl compiler. To fix this problem, run cmake from the
Visual Studio Command Prompt (vcvarsall.bat)."
Try to compile using the Visual Studio command prompt. The path to it there should be correct too.

The best method to install dlib and openCV is given here.
It simply uses pip to perform all the installations.
The major things that people miss or do a mistake in for Windows are declaring the PATH variables and saving them to valid address in your pc apart from the proper version matching. The above blog clearly signifies the versions to be used and declarations of PATH variables.
Just a 3 step process:-
Install anaconda
Activate Virtual Environment
Install openCV and dlib using pip (or any other required packages)

Linux error solution
$ sudo apt-get install build-essential cmake
$ sudo apt-get install libgtk-3-dev
$ sudo apt-get install libboost-all-dev
$ pip3 install dilb

Use the following code in the terminal which is accessible through Alt+F12 on your keyboard.
pip install dlib==19.8.1
You should be good to go.
