为了解决这个问题在router文件夹index.js里配置了以下代码就可以解决啦:
const originalPush = VueRouter.prototype.push
VueRouter.prototype.push = function push(location) {
return originalPush.call(this, location).catch((err) => err)

背景:项目通过菜单栏切换界面时候出现如下问题,虽然不影响界面的切换及系统的使用,但是会影响到系统的稳健性。
原因:上面截图显示的问题是系统进行路由切换时出现的问题,主要是vue-router版本问题,vue-router 3.0版本以上的回调形式是promise api的形式,返回的是一个promise,如果没有捕获到错误,控制台始终会出现上图的警告。
解决方法:
1.安装低版本的vue-router或者捕获抛出放入错误;
2.删除node_modules文件夹,然后使用“cnpm install”重新安
在安装axios的时候,运行然后报一大堆错,比如
error in ./node_modules/axios/index.js
Module build failed: Error: ENOENT: no such file or directory, open 'src/'
Uncaught Error: Module build failed: Error:
EPERM: operation not permitted, open '\node_modules\webpack\hot
错误解决 node_modules/cache-loader/dist/cjs.js??ref--12-0!./node_modules/babel-loader/lib!./node_modules
cnpm install(这一步报错cnpm不是内部或外部命令的话,
cnpm -v 看下有没有版本号,
然后 npm install cnpm -g --registry=https://registry.npm.taobao.org)
npm run serve
二级标题webpack-internal:///./node_modules/vue/dist/vue.esm.js:629 [Vue warn]: Invalid prop: type check failed for prop “dataSource”. Expected Array, got String with value “”.
found in
这种报错
应该怎么修改
1、首先f12看一下我们报什么错
这个错 一看就是 data(){
这里边的错
换完以后还是报错,
改完一个错基本都
Vue-router提供了三种路由模式:hash模式、history模式和abstract模式。\[2\]其中,hash模式是默认模式,URL后面带有#,使用URL的hash值来作为路由,支持所有浏览器。\[3\]history模式通过设置mode: 'history'来改变,使用HTML5的History API来实现路由,可以使页面跳转而不刷新,页面的状态被维持在浏览器中。\[2\]但是,history模式的缺点是如果后端没有处理刷新的情况,前端刷新会发送实际的请求到服务器,导致消耗时间较多且较慢。\[3\]最后,abstract模式是一种抽象模式,具体细节没有提及。
