1. 在package.json中修改运行脚本
添加--exec babel-node
添加之后的效果为：（修改了8/10行）
{
"name": "nuxt-learn",
"version": "1.0.0",
"description": "My lovely Nuxt.js project",
"author": "wqzhai",
"private": true,
"scripts": {
"dev": "cross-env NODE_ENV=development nodemon server/index.js --watch server --exec babel-node",
"build": "nuxt build",
"start": "cross-env NODE_ENV=production node server/index.js --exec babel-node",
"generate": "nuxt generate"
},
"dependencies": {
"@nuxtjs/axios": "^5.0.0",
"babel-cli": "^6.26.0",
"babel-core": "^6.26.3",
"babel-preset-es2015": "^6.24.1",
"babel-preset-stage-0": "^6.24.1",
"cross-env": "^5.2.0",
"element-ui": "^2.4.6",
"koa": "^2.5.2",
"nuxt": "^2.0.0"
},
"devDependencies": {
"nodemon": "^1.11.0"
}
}
2.安装编译工具
npm i babel-cli // 这是babel解释器的客户端主程序
npm i babel-core // babel的核心文件,好像默认会自动安装
npm i babel-preset-es2015 // 把代码转换成ES6
npm i babel-preset-stage-0 // 把代码转换成ES7
3.在根路径创建.babelrc文件，写入配置
.babelrc
{
"presets": ["es2015","stage-0"]
}
