在新建一个vue2的项目时,安装vue-router时,报了下面这个错误:
npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

原因:
是因为vue-router默认版本的问题,新版本对下载要求比较严格,在2022年2月7日以后,vue-router的默认版本,为4版本,而且 vue-router4,只能在vue3中,只有vue-router3中,能用在vue 2中,如果把vue-router4强制安装到vue2中,则会报上面的错误;
解决方法:
在vue2的项目中,安装vue-router3版本
执行命令:npm i vue-router@3
