SyntaxError：node_modules / aws-iot-device-sdk / thing / index.js中的意外标记

问题描述 投票：0回答：1

我在reactjs应用程序中使用aws-iot-device-sdk。我们在运行NODE_ENV = production npm run compile命令时遇到错误。以下是我得到的错误，我附加了我的webpack配置和node＆npm的版本。

Module parse failed: /Users/Anesh/react/aws-iot-example/node_modules/strip-loader/lib/index.js?strip[]=console.log!/Users/Anesh/react/aws-iot-example/node_modules/aws-iot-device-sdk/thing/index.js Unexpected token (499:11)

我的笔记本电脑中安装了以下版本

node: v7.3.0

if (__PROD__) {
   webpackConfig.module.loaders.push({
     test: /\.js$/,
     loader: WebpackStrip.loader('console.log')
   })
}

上面的配置没有正确地剥离console.log语句。我刚刚使用了一些入门套件，但没有注意到这件事。根据我的知识，我们应该在自我欺骗的同时剥离代码类的东西。
