入手vue的软件开发前端项目，发生问题如下

PS F:\vuedev\ysbWap> npm install
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

PS F:\vuedev\ysbWap> node -v
v16.14.0
PS F:\vuedev\ysbWap> npm install --legacy-peer-deps

今天拿到之前vue软件开发项目进行维护，报错ERESOLVE unable to resolve dependency tree。根据提示执行

npm install --legacy-peer-deps

如此执行成功！解决问题。
