What is your question? Please don't just dump an error message here. Esspecially when the error message has a clear message: CMake must be installed. Make sure to indicate where your specific problem is – Lemoine

Actually when i am trying to pip install face_recognition package on my windows machine, i am getting error CMake must be installed to build the following extensions: dlib. Then i pip install CMake and then ran pip install face_recognition again but still getting same error. – Yoke

Does this answer your question? where should i install CMake? – Borlow

Answer 1

I ran into this issue as well. I am using windows and have a python environment that I am installing the requirements to.

I ran pip install cmake , and then pip install dlib. I no longer received the error and successfully installed dlib.

Answer 3

I also had the same issue. For those who deals with it now -

Firstly you have to install visual studio, and than install there the extension "tools for CMake". Look at the installation part here: https://learn.microsoft.com/en-us/cpp/build/cmake-projects-in-visual-studio?view=vs-2019

Only after that you will be able to pip install this package.

So:

1. Install VS
2. Install the extension "tools for CMake"
3. Of course you should also have the python interpreter installed
4. In the command line:
   • pip install CMake
   • pip install face_recognition

Edit: Not checked, but if you don't have Visual Studio installed, try install "CMake Tools" separately, maybe from here: https://marketplace.visualstudio.com/items?itemName=vector-of-bool.cmake-tools

Answer 4

Updated

Follow these steps from the start.

1 - Downgrade to python 3.6.8.

2 - Install visual studio UPDATE 3

People usually have visual studio 2015 and the process still doesn't work and the reason is the update. You have to update it to update 3.

OR

Install visual studio 2015 Update 3 from here

Now, some people have already installed VS 2015 so how to update?

Launch Visual Studio > Tools > Extensions And Updates > New Window Will open, navigate left and click on Updates > Update

3 - Download and install CMake from here. During installation, Check the Add To Path CheckBox.

4 - pip install cmake

5 - pip install face_recognition
