qdldl的构建轮失败(安装vxpy时)

Question

无论我使用pip还是从源代码安装，无论我使用python2还是python3，我都无法安装cvpy。我已经试了四个多小时了，但还是失败了。cvxpy或qdldl的github页面不会给我任何解决方案。我安装了导致其他错误的软件包，但没有成功。如有任何提示，不胜感激。

Disabling LONG
Remove long integers for numpy compatibility. See:
- https://github.com/numpy/numpy/issues/5906
- https://github.com/ContinuumIO/anaconda-issues/issues/3823
You can reenable long integers by passing: --osqp --long argument.

您可以安装osqp <0.6.2，不依赖于qdldl-python来安装cvxpy

pip3 install osqp==0.6.1
