  ERROR: Failed building wheel for numpy
Failed to build numpy
ERROR: Could not build wheels for numpy, which is required to install pyproject.toml-based projects.

I don't know why this errors happened. Note that I should install 1.18.1 numpy for the project.

Could you help me?

Thanks.

Answer 1

Try updating pip: pip install --upgrade pip on command line

Answer 2

Try this command (worked for me):

python -m pip install --force-reinstall numpy==1.18.1

Answer 3

The first solution to remove this error is to first upgrade the pip command. After upgrading try to install the NumPy version using the pip command. But make sure to check the version of the python.
