webpack问题

webpack jsx Unexpected token:

配置loader

{
  test: /\.js[x]?$/,
  loaders: ['react-hot', 'babel?presets[]=es2015&presets[]=react'],
  exclude: path.join(rootPath, 'node_modules')
}

或者添加到 .babelrc文件

Failed at the node-sass@3.13.1 postinstall script

缺少python的编译环境，安装node-gyp和gym：

npm install -g node-gyp 
npm install –global –production windows-build-tools

Found bindings for the following environments: - Windws 64-bit with Node.js

Nodejs版本不兼容

添加async的时候webpack打包报错

安装async的解析插件

npm install --save-dev babel-plugin-transform-async-to-generator

添加到 .babelrc文件

{"plugins": ["transform-async-to-generator"]}

安装后运行可能再次报错：regeneratorRuntime is not defined

安装babel-polyfill

npm install --save-dev babel-polyfill

在webpack配置文件添加

require("babel-polyfill");
module.exports = {
  entry: ['babel-polyfill', './test.js'],

  ......
};
