断言错误：将使用不受支持的标签构建轮子（'cp310'、'cp310'、'linux_x86_64'）

Question

I've got this message when I try to install numpy using Python 3.10.

How to fix this?

  Copying numpy.egg-info to build/bdist.linux-x86_64/wheel/numpy-1.19.3-py3.10.egg-info
  running install_scripts

Answer 1

It's a bug in python 3.10, a workaround is installing numpy with the --no-use-pep517 flag. Eg: pip3.10 install numpy --no-use-pep517

There's a fix for this on the way though, so just waiting is an option as well.
