I want to install pinocchio, but meet this problem:

CMake Error at cmake/python.cmake:197 (message):
Python executable has not been found.
Call Stack (most recent call first):
CMakeLists.txt:303 (findpython)

Does anyone know how to do?

Hi, thanks for your interest in Pinocchio! I'll ask a few questions for further info:

What is your operating system?

Against what kind of environment are you trying to build Pinocchio ? A conda env, a virtualenv, system (i.e. installed through apt, pacman...) Python ?

What CMake command did you run ?

Normally, by setting the CMake variable PYTHON_EXECUTABLE when running the cmake command should solve your issue:

cmake . -DPYTHON_EXECUTABLE=$(which python3)
