Uncaught (in promise) TypeError: Cannot read property ‘_normalized‘ of undefined（Vue中使用$router报错）

Uncaught (in promise) TypeError: Cannot read property '_normalized' of undefined（Vue中使用$router报错）

具体如下：

Uncaught (in promise) TypeError: Cannot read property '_normalized' of undefined
    at normalizeLocation (vue-router.esm.js?8c4f:969)
    at Object.match (vue-router.esm.js?8c4f:1491)
    at VueRouter.match (vue-router.esm.js?8c4f:2850)
    at HTML5History.transitionTo (vue-router.esm.js?8c4f:2144)
    at HTML5History.push (vue-router.esm.js?8c4f:2519)
    at eval (vue-router.esm.js?8c4f:2950)
    at new Promise (<anonymous>)
    at VueRouter.push (vue-router.esm.js?8c4f:2949)
    at VueComponent.activated (Home.vue?76f2:16)
    at invokeWithErrorHandling (vue.runtime.esm.js?2b0e:1854)

出错原因：

使用this.$router.push(this.path)报错  虽不影响结果  但是有个红叉  得改

解决办法：router下的index.js添加push重写

const routerPush = VueRouter.prototype.push
VueRouter.prototype.push = function push(location) {
  return routerPush.call(this, location).catch(error=> error)
}
