webpack modules.export 未定义

Question

NPM、Node 和 webpack 版本是

C:\>npm --version
5.3.0

C:\>node --version
v6.10.2

C:\>webpack --version
3.3.0

我已经创建了标准的 scala/Play2 项目。在其中，我在 app/ts 文件夹中添加了 4 个 Typescript 文件（Angular）。我还创建了以下 webpack 配置文件

modules.export = {
    entry: [
        '/ts/main.ts',
        '/ts/vendor.ts'
    ],
    output:{
        filename:'[name].bundle.js'
    },
    rules:
        {
            test:'/\.ts$/',
            loader:'awesome-typescript-loader'
        }
}

为了让事情运行（下载依赖项并执行 webpack 将 ts 转换为 js），我编辑了播放配置并在“启动前”部分添加了两个 npm 命令（见图）。但是在运行应用程序时，npm start 声明模块未定义的错误（参考 webpack.config.js 中的 modules.export 语句）

Answer 1

您的webpack.config.js 必须以module.exports 而不是modules.export 开头。

它以编程方式表示简单的英语等价物：“此模块导出”。
