背景：
mac电脑升级后重新拉取老项目后安装node_module 和启动项目报错
gyp info using node-gyp@3.8.0
gyp info using node@14.18.0 | darwin | x64
gyp verb command rebuild []
gyp verb command clean []
gyp verb clean removing "build" directory
gyp verb command configure []
gyp verb download using dist-url https://npm.taobao.org/dist
gyp verb check python checking for Python executable "python2" in the PATH
gyp verb `which` failed Error: not found: python2
gyp verb check python checking for Python executable "python" in the PATH
gyp verb `which` failed python Error: not found: python
gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.
解决方案1：使用sass 不使用node-sass
npm uninstall node-sass
npm i -D sass
npm i
参考npm ERR! gyp verb check python checking for Python executable "python2" in the PATH · Issue #20 · themesberg/volt-react-dashboard · GitHub
解决方案2: 根据提示应该是缺少python环境 安装python环境然后设置应该可行

PS：因为我这个项目要的比较急，然后我使用第二种方式太慢了，而且短时间也报错没安装上，所以 我使用的是第一种方式
