具体问题如下：
npm ERR! code ERESOLVE npm ERR! ERESOLVE unable to resolve dependency tree npm ERR! npm ERR! While resolving: XXX@3.4.0 npm ERR!

2、问题分析
npm版本过高
3、问题解决
npm install npm@6.14.10 -g
如果还提示出现 python 的信息，说明还需要安装python，去python官网下载对应版本的安装包安装即可，一般是2.7版本。python官网下载
如果提示 这些等乱七八糟的基本上就是node-sass 版本冲突问题
gyp ERR! node -v v14.19.1 gyp ERR! node-gyp -v v8.4.1 gyp ERR! not ok直接去npm官网查看 使用nvm控制node版本或者 npm install node-sass@4.14（示例4.14）安装指定版本node-sass!!!
