推荐答案
虽然丑陋，但似乎可以使用
While it's ugly, it appears to work
sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install --upgrade numpy
请注意，如果对于除numpy之外的其他程序包遇到此错误，(例如lxml)请在该命令的末尾指定该程序包名称，而不是numpy.
Note that if you are getting this error for a package other than numpy, (such as lxml) specify that package name instead of numpy at the end of the commnd.
