Vue项目报错：Uncaught (in promise) NavigationDuplicated: Avoided redundant navigation to current location

我在使用路由跳转的时候，跳转不了，浏览器报错：

Uncaught (in promise) NavigationDuplicated: Avoided redundant navigation to current location: “/main”.
createRouterError vue-router.esm.js:2065
createNavigationDuplicatedError vue-router.esm.js:2035
confirmTransition vue-router.esm.js:2328
transitionTo vue-router.esm.js:2260
push vue-router.esm.js:2704
push vue-router.esm.js:3020
push vue-router.esm.js:3019

错误原因是我没有加：

<router-view></router-view>
