你的代码可以build了吗，我的也不可以

{

"name": "vue-webpack",

"version": "1.0.0",

"main": "index.js",

"scripts": {

"test": "echo \"Error: no test specified\" && exit 1",

"start": " cross-env MODE_ENV=development webpack-dev-server --config build/webpack.config.js",

"build": "cross-env MODE_ENV=production webpack --config build/webpack.config.js"

}

你前面npm install 没有安装vue-template-compiler

index.js 就是这样

index.js代码是怎么写的？
