cnpm install -g babel-clinpm initcnpm install babel-preset-es2015 --save{ "name": "es6", "version": "1.0.0", "description": "", "main": "index.js", "babel": { "presets": ["es2015"] }, "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "author": "", "license": "ISC", "dependencies": { "babel-preset-es2015": "^6.24.1" }}问题:1.配置cnpm install babel-preset-es2015 --save 时提示deprecate. 2.在package.json中添加了"babel": { "presets": ["es2015"]},但是在命令行中babel index.js还是报错,这样加参数就行babel index.js --presets es2015
