node-sass安装失败
下面不用看了，遇到node-sasa问题直接卸载node-sass
安装sass进行替代，不过需要解决一下deep的应用
以前的/deep 修改为 ::v-deep ok,完美解决，终于不用再为node-sass头疼啦!!!!!
试了很多方法都没有解决安装问题，最直接粗暴的解决方式就是
npm uninstall node-sass
然后执行npm i
再安装 node-sass
因为是新环境所以还遇到了python2.7的问题，如下
gyp verb command configure []
gyp verb check python checking for Python executable "python2.7" in the PATH
gyp verb `which` failed Error: not found: python2.7

需要下载python2.7,推荐
华为镜像：Index of python-local/2.7 (huaweicloud.com)
下载安装，不要修改安装地址直接确定即可
