問題描述

在項目代碼中加入下面這句代碼的時候會報錯

var fetch = require(’node-fetch’);

錯誤代碼:

webpack.config.js配置

var webpack = require(’webpack’);path = require(’path’);module.exports = { entry: {’./sdk/dist/websdk-1.1.3’: ’./sdk/src/connection’,’./demo/javascript/dist/demo’: ’./demo/javascript/src/entry’,’./webrtc/dist/webrtc-1.0.0’: ’./webrtc/src/webrtc’, }, output: {path: ’./’,publicPath: ’./’,filename: ’[name].js’ }, // devtool: ’#eval-cheap-module-source-map’, resolve: {extensions: [’’, ’.js’, ’.jsx’] }, module: {loaders: [ {test: /.(js|jsx)$/,loader: ’babel’,exclude: /node_modules/, }, {test: /.scss$/,loader: ’style!css!sass’ }, {test: /.svg|woff|eot|ttf$/,loader: require.resolve(’file-loader’) + ’?name=[path][name].[ext]’ }, {test: /.json$/,loader: 'json-loader' }] }, plugins: [// new webpack.NoErrorsPlugin(),// production must be with `UglifyJsPlugin` or ie9 crash// faster your app better use// https://github.com/facebook/react/issues/7803new webpack.DefinePlugin({ ’process.env’: {’NODE_ENV’: ’'production'’ }}),new webpack.optimize.UglifyJsPlugin({ compressor: {warnings: false }}) ],};

問題解答

需要添加 json loader

如果你的代碼同時需要在瀏覽器端和node端運行，建議使用 isomorphic-fetch，兼容兩個平臺

I received this same exact error. You’ll want to install a JSON loader module. I’m using json-loader in this example.

npm install json-loader --saveThen, you need to add this loader to your webpack.config.js

module: {

loaders: [ { test: /.json$/, loader: 'json-loader'}]

}
