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

Answer 1

Numpy has not yet released a precompiled wheel for Python 3.10. What you can do, is downgrade to python 3.9. If you don't want to do this, you can try the unofficial wheels available here .

These are the important ones you should look for:

• numpy‑1.21.2+mkl‑cp310‑cp310‑win_amd64.whl
• numpy‑1.21.2+mkl‑cp310‑cp310‑win32.whl

(Choose based on your OS architecture)

Then download the file, go to your downloads folder, and run pip install "<your_filename_choice>.whl") .

You could also just use the pipwin module. Do this:

pip install pipwin

and then

pipwin install numpy

Answer 2

I faced the same issue, I have a macos high sierra with python 3.10 and I have the same error while installing numpy in pip. I managed to solve the problem by installing not the newest numpy 1.22.2 in pip. I install version 1.22.1 .

Command:

pip install numpy==1.22.1

Note that wheels have been available for Python 3.10 since 5th November, see:

https://pypi.org/project/numpy/#files

specifically, I can see Python wheels for labelled as version cp310 (ie CPython 3.10) for Linux, Mac and Windows.
