【问题描述】：
我正在为 es2015 使用 Babel 6 并做出反应，这需要 babel-preset-es2015 和 babel-preset-react。
我在.babelrc 中添加了presets 属性，但它抛出了一个错误：
ERROR in ./src/client/entry.js
Module build failed: ReferenceError: [BABEL] /Users/brick/Dropbox/learncoding/node.js/isomorphic/src/client/entry.js: Unknown option: /Users/brick/Dropbox/learncoding/node.js/isomorphic/.babelrc.presets

@ multi main
我的.babelrc 文件是：
{
"presets": [
"es2015",
"react"
]
}
我可以运行babel src -d lib 命令，它可以工作。但是如果我运行npm start 通过package.json 运行babel，就会出现错误。
我想我可以忽略该错误，因为应用程序正在运行。但我想知道为什么会出现这个错误，但不确定它会影响什么。
我在package.json 中的scripts 是：
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"clean": "rm -rf lib",
"build": "npm run clean && /usr/local/bin/babel src -d lib --experimental",
"server": "nodemon lib/server/server",
"dev-server": "node lib/server/webpack",
"watch-js": "/usr/local/bin/babel src -d lib --experimental -w",
"start": "npm run watch-js & npm run dev-server & npm run server"
},
我的entry.js 是
import React from "react";
import Router from "react-router";
import ReactDOM from "react-dom";
import routes from "./routes";
import DataWrapper from './DataWrapper';
import createBrowserHistory from 'history/lib/createBrowserHistory';
let history = createBrowserHistory();
var data = JSON.parse(document.querySelector('#data').innerHTML);
ReactDOM.render(<DataWrapper data={data}><Router history = {history}>{routes}</Router></DataWrapper>, document.querySelector('#app'));
