@gd1m3y

Is CMAKE installed in your system?

[maheshwarkuchana]

@gd1m3y
If you have conda installed in your system follow this process.

conda create -n py36 python=3.6
activate py36
conda config --add channels conda-forge
conda install numpy
conda install scipy
conda install dlib

Here I install face_recognition once to make sure all the dependencies is included.

pip install face_recognition

Note that here the installation will fail because pip fail to detect the dlib conda installed earlier
Therefor I run

pip install --no-dependencies face_recognition

This should complete installation. I was able to run dlib fine.
For more info I recommend checking out #81

[ManivannanMurugavel]

First install Dlib seperate after you can install face_recognition

1. download: https://cmake.org/download/
2. set path environment: https://stackoverflow.com/a/52803626/2696230
3. Install Vistual Studio Tools
4. Open Developer Command Prompt
5. download face_recognition source
6. python setup.py install

[kevinunger]

Solved the issue by install cmake via pip
pip3 install cmake

[NikhilCodes]

If any windows user is looking for precompiled dlib (whl file) then go this link follow instruction and download

Try to install through anaconda prompt

pip install cmake

pip --no-cache-dir install face_recognition

It works.

[RvTechiNNovate]

try install cmake
and install face_recognition_dlib file manually

Or go here all dlib error solved

[Akash-ik]

Try this for anaconda
conda install -c conda-forge face_recognition
