今天安装davisinteractive，先是用pip install davisinteractive -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com 的方法，发现无法安装：
note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure
× Encountered error while trying to install package.
╰─> davisinteractive
note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.
然后试着从GitHub下载包文件进行安装：https://github.com/albertomontesg/davis-interactive
下载完成后解压，进入文件目录，执行python setup.py install，还是报错：

但从错误提示来看，可以将setup.py 的extra_compile_args=['-Wno-cpp', '-Wno-unused-function', '-std=c99'], 语句改为extra_compile_args={'gcc': ['/Qstd=c99']},
再次执行python setup.py install，成功安装。
