刚刚开始学习webpack+vue的项目开发,配置好之后用webpack-dev-server运行，但是页面什么都没有，也没报错。找了两天还是不知道什么原因。
下面是代码
package.json
{
"name": "webpack_project2",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"dev": "webpack-dev-server --open --config webpack.config.js"
},
"author": "",

"vue": "^2.5.16"
},

"babel-core": "^6.26.0",
"babel-loader": "^7.1.4",

import Vue from 'vue';
new Vue({
el:'#app',
data:{
hello:'hello world'
},
beforeCreate:function(){
console.log("beforeCreate")
},
created:function(){
console.log("created")
},
beforeMount:function(){
console.log("beforeMount")
},
mounted:function(){
console.log(this.hello)
},
beforeUpdate:function(){
console.log("beforeUpdate")
},
updated:function(){
console.log("updated")
},
template:
`
<div>
<p>{{hello}}</p>
</div>
`
})
console.log('main.js正在运行')webpack.config.js
var path = require('path');
var config = {
entry:{
main:'./main.js'
},
output:{
path:path.join(__dirname,'./dist'),
publicPath:'/dist/',
filename:'[name].bundle.js'
},
module:{
rules:[
{
test:/\.vue$/,
loader:'vue-loader',
},
{
test:/\.js$/,
loader:'babel-loader',
exclude:/node_modules/
},
{
test:/\.css$/,
loader: "css-loader!style-loader"
}
]
}
};
module.exports = config;运行结果
页面上一片白板，什么都没有，控制台没有报错
