当我尝试使用Webpack和Babel-loader构建我的应用程序时，我收到此错误：
ERROR in ./src/entry.js
Module parse failed: /home/james/projects/fun-time-phonics/node_modules/babel-loader/index.js!/home/james/projects/fun-time-phonics/src/entry.js Line 1: Unexpected token
You may need an appropriate loader to handle this file type.
| import React from "react";
| import onReady from "./on-ready";
| import "babel-polyfill";
我的.babelrc看起来像这样：
{
"presets": ["react", "stage-0"]
}
相关的webpack加载器：
{test: ext("js"), exclude: /node_modules/, loader: "babel"}
模块版本：
"webpack": "^1.12.1",
"babel": "^6.3.26",
"babel-core": "^6.4.0",
"babel-loader": "^6.2.1",
"babel-preset-react": "^6.3.13",
"babel-preset-stage-0": "^6.3.13",
Babel 5的一切都很好。任何帮助都会非常感激。
更新：
添加babel-preset-es2015后，我的构建现在在静态类属性上失败（尽管babel-preset-stage-0添加了静态属性）：
