Vue-router cannot read property _c of undefined

Vue-router Exception

当点击“商品”标签的时候,consolse（控制台）跳出
cannot read property _c of undefined的异常

此时观察你的main.js中routes添加组件的时候：
和path相对应的一定是component，不是components,正确答案如下

const routes = [
  {path: '/goods', component: goods},
  {path: '/ratings', component: ratings},
  {path: '/sellers', component: sellers}
];

而不是

const routes = [
  {path: '/goods', components: goods},
  {path: '/ratings', components: ratings},
  {path: '/sellers', components: sellers}
];

希望能帮到你
