内容简介:解决方案:在最外边 包上一个容器(不允许直接返回多个元素)vue.js:435 [Vue warn]: Unknown custom element: <my-footer> - did you register the component correctly? For recursive components, make sure to provide the "name" option.原因:你把局部组件当成全局组件去使用了
- vue.js 2.0要求每个template只能有一个根元素。可以在最外层包一个div来解决这个问题。
vue.js:435 [Vue warn]: Error compiling template:
<h2>这是页头</h2> <button>登录</button>
Component template should contain exactly one root element. If you are using v-if on multiple elements, use v-else-if to chain them
instead.
解决方案:在最外边 包上一个容器(不允许直接返回多个元素)

vue.js:435 [Vue warn]: Unknown custom element: <my-footer> - did you register the component correctly? For recursive components, make sure to provide the "name" option.
原因:你把局部组件当成全局组件去使用了
解决方案:
正确的注册组件
3、 The "data" option should be a function that returns a per-instance value in component definitions.
原因:在组件中去初始化数据 不允许给data直接赋值一个对象
解决方案: Vue.component('',{
data:function(){ return {} } })
4、Uncaught TypeError: Cannot read property 'push' of undefined
原因:push前面的那个变量,其实undefined
解决方案:
this 通过箭头函数来解决问题
5、ERROR in ./src/assets/img/favicon.ico
Module parse failed: C:xampphtdocsframeworkvueprojecttplssrcassetsimgfavicon.ico Unexpected character '' (1:0)
You may need an appropriate loader to handle this file type.
(Source code omitted for this binary file)
解决方案:找到build/webpack.base.conf.js
在41行加上 |ico
6、No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' http://localhost :8080' is therefore not allowed access.
