解决方法：npm install --global cross-env ，重新执行：npm install --no-bin-links

报错：VueRouter is not a constructor

Solution 1: ES Module Import
In Laravel’s default config [at least], vue-router is expected to be imported as an es module. So, it should be done at the top of the file.

在这里插入代码片import VueRouter from 'vue-router'

Solution 2: CommonJS Require
Since vue-router router is an es module, you will have to explicitly access the default property of the CommonJS version of the module.

const VueRouter = require('vue-router').default;
