我的 bootstrap.js 如下
import Vue from 'vue';
import VueRouter from 'vue-router';
import axios from 'axios';
// Global variable for API access
window.hostname = 'https://city.molotex.ru/cgi-bin/citygate.py?';

我的路由文件如下:
import VueRouter from 'vue-router';
let routes = [
{
path: '/',
component: require('./components/Example.vue')
},
{
path: '/about',
component: require('./components/About.vue')
},
{
path: '/login',
component: require('./components/Login.vue')
},
{
path:'/user_main_page',
component: require('./components/UserMainPage.vue')
}
];
export default new VueRouter({
routes
});

但是当我出现以下错误时:
类型错误:无法在 app.js:4341 处读取未定义的属性“$router”
我尝试了不同类型的路由,例如:使用全局路由变量为:window.router = VueRouter;
或在组件内导入 VueRouter,但这两种方法都没有帮助。我做错了什么,如何让路由器工作。

我假设您发布的代码就是全部,并且您遇到的错误可以在 Login Vue 组件的这个块中进行追踪,您在其中引用了 $router 变量。
axios.post('/login', {
email: this.email,
password: this.password
}).then(function (response) {
self.response_key = response.data.result;
this.$router.push('/user_main_page');
console.log(response);
}).catch(function (error) {
console.log(error);
});

尽管 this.$router 是访问路由器依赖项的正确语法,但在回调函数中调用它,使用正则函数表达式,会创建一个到“this”对象的新绑定,而不是 Vue 对象本身。
您有两种选择来解决这个问题:
const vm = this;
axios.post('/login', {
email: this.email,
password: this.password
}).then(function (response) {
self.response_key = response.data.result;
vm.$router.push('/user_main_page');
console.log(response);
}).catch(function (error) {
console.log(error);
});

}).then(response => {
self.response_key = response.data.result;
this.$router.push('/user_main_page');
console.log(response);
}).catch(error => {
console.log(error);
});
