官网installation安装先试一遍 不行再考虑下面的
要先 brew install cmake

Apple M1 users have had trouble installing CVXPY using the commands above. That trouble stemmed partly from a configuration error in CVXPY’s pyproject.toml, which has been fixed in CVXPY 1.1.19 and 1.2.0. If you have those versions (or newer) then the above commands should work provided (1) you have cmake installed via Homebrew and (2) you have an ECOS 2.0.5 wheel. The cmake requirement stems from OSQP and there appear to be problems building more recent versions of ECOS on M1 machines. See this comment on the CVXPY repo and this issue on the ECOS repo for more information.
指定安装ecos的版本
ecos==2.0.5

我的方法：
- 依赖库要全部先安装好
- 下载源码 source code 安装
If you want to use CVXPY with editable source code, run
pip install -e .
otherwise, run
pip install .
输入命令：arch -x86_64 pip install -e .
arch -x86_64 pip install -e .
