Vuejs2 vue路由器可以'；我无法访问我的组件

正如所问，我的vue路由器似乎找不到我的组件

我需要说的是，我在用户输入之后添加了一个新的路由，然后我无法访问这个特定的路由。我在

router.js

中创建的静态路由仍在工作。 我已尝试使用全局导入组件

import componentName from "./views/componentName"
Vue.component("componentName")

还尝试只在路由器或我放置链接的组件中导入该组件，该链接将我们发送到该组件

然后，我收到以下错误消息：

[Vue warn]：装载组件失败：未定义模板或渲染功能

这是我的密码：

router.js：

import Vue from "vue";
import Router from "vue-router";
Vue.use(Router);
import About from "./views/About.vue";
import Menu from "./views/Menu.vue";
import Home from "./views/Home.vue";
import Test from "./views/Test.vue";
export default new Router({
  routes: [
  {
    path: "/home",
    name: "home",
    component: Home
  },
  {
    path: "/about",
    name: "about",
    component: About
  },
  {
    path: "/menu",
    name: "menu",
    component: Menu
  }
  ]
});

main.js：

import Vue from "vue";
import App from "./App.vue";
import router from "./router";
import store from "./store";
import componentPlugin from "./componentPlugin";
import BootstrapVue from "bootstrap-vue";
import "bootstrap/dist/css/bootstrap.css";
import "bootstrap-vue/dist/bootstrap-vue.css";

Vue.config.productionTip = false;

new Vue({
  router,
  store,
  render: h => h(App)
}).$mount("#app");
Vue.use(componentPlugin);
Vue.use(BootstrapVue);

组件插件：

import List from "./components/List.vue";
import MainMenu from "./components/MainMenu.vue";
import Test from "./views/Test.vue";
import About from "./views/About.vue";
import Menu from "./views/Menu.vue";
import Home from "./views/Home.vue";

export default {
  install(Vue) {
    Vue.component("List", List);
    Vue.component("MainMenu", MainMenu);
    Vue.component("Test", Test);
    Vue.component("About", About);
    Vue.component("Menu", Menu);
    Vue.component("Home", Home);
  }
};

List.vue：

我正在使用Vue v2.5.17和Vue路由器2.0

如果您需要更多信息，请告诉我。
您不能像这样全局定义组件。全局声明组件时，您忘记声明此组件的内容和功能。此问题已在错误报告中指出

正确的定义代码应该是这样的

import componentName from "./views/componentName"
Vue.component("componentName", componentName)

您可以在官方手册中找到并定义更多的组件和语料库定义


希望对你有帮助

import componentName from "./views/componentName"
Vue.component("componentName", componentName)
