Error installing requirements - dlib

I am not able to install dlib it seems. I tried changing it to dlib-bin as suggested in one of the answers as well but it dindn’t work. Adding cmake in requirements.txt gives same error.
App link:

I am new to this and following the tutorial. I have tried other platforms like render and cyclic too and it is stuck in dlib part. I am not able to figure out how to solve this.

Error Message:

 note: This error originates from a subprocess, and is likely not a problem with pip.

Found one solution in the community. It solved my issue.

Hey @Bijay_Shah ,

just to clarify, did you also mention dlib under requirements.txt?

Libraries don’t always function properly when deployed if their working version is not mentioned in that file.

dlib-bin worked and forking the face_recognition library helped.
