En cliquant sur copilot 'explain error" depuis l'onglet action voici ce qu'il me propose :
The job failed because CMake could not find the Python3 "Development", "Development.Module", and "Development.Embed" components. Although Python 3.12.10 was detected, its development headers/libraries were missing. This error occurred at line 29 in CMakeLists.txt during the find_package(Python3 ...) step.
Solution:
-
Ensure the Python development package is installed in your CI environment. For Python 3.12 on Windows, install it with:
pip install pybind11
# Make sure the Python dev headers are present.
Or, for a more robust solution, add the following to your workflow before CMake is invoked:
- name: Add Python dev headers (Windows)
run: |
choco install python --version=3.12.10
python -m pip install --upgrade pip setuptools wheel
-
Update your CMakeLists.txt to explicitly require the Development component:
find_package(Python3 COMPONENTS Interpreter Development REQUIRED)
If you only need the Interpreter (and not embedding or module development), remove unnecessary components.
-
If using cibuildwheel or conan, ensure the Python executable used by these tools matches the one with development headers.
Code suggestion for CMakeLists.txt:
find_package(Python3 COMPONENTS Interpreter Development REQUIRED)
# If you need Embed or Module, add them to COMPONENTS
If you need help editing the workflow or diagnosing which Python is being picked up, let me know!
Reference:
- Error at CMakeLists.txt:29 (view source).
- Full error:
Could NOT find Python3 (missing: Development Development.Module Development.Embed).
Summary:
Install Python development headers and ensure CMake requests the correct components. This will resolve the "Could NOT find Python3" issue and allow the build to proceed.
