所以，我的项目结构如下：

|   package.json
|   tree.txt
|   tsconfig.json
|   webpack.config.js

|   \---modules
|           app.module.js
|           app.module.js.map
|           app.module.ts
|           
\---node_modules

    *SNIP*

我的问题是只有我的main.ts源图在chrome dev工具中显示为实际的打字稿，app.module，app.component和test显示为已编译的javascript。

我设法找到的有关webpack打字稿的任何其他问题都是特定于babel加载程序，根本没有生成断点或源图的问题。

我的tsconfig：

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "moduleResolution": "node",
        "sourceMap": true,
        "watch": true,
        "compileOnSave": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "noImplicitAny": false
    },
    "exclude": [
        "node_modules",
        "typings/browser",
        "typings/browser.d.ts"
    ],
    "atom": {
        "rewriteTsconfig": false
    },
    "typeRoots": [
        "./node_modules/@types"
    ],
    "types": [
        "core-js"
    ]
}

我的webpack.config.js：

const config = {
    entry: {
        app: "./app/main.ts"
    },
    output: {
        filename: "./bundle.js",
        path: "./"
    },
    devtool: "source-map",
    module: {
        loaders: [
            {
                test: /\.ts$/,
                loaders: ["awesome-typescript-loader", "angular2-template-loader"]
            }
        ]
    },
    resolve: {
        extentions: ["", ".ts", ".js"]
    }
}

module.exports = config;

主要的Chrome开发工具输出：

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './modules/app.module';
import { test } from "./test";
const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);
alert(test.msg)


// WEBPACK FOOTER //
// ./~/angular2-template-loader!./app/main.ts

适用于test.js的Chrome开发工具输出：

"use strict";
var test = (function () {
    function test() {
    }
    test.msg = "test";
    return test;
}());
exports.test = test;
//# sourceMappingURL=test.js.map


//////////////////
// WEBPACK FOOTER
// ./app/test.js
// module id = 25
// module chunks = 0

所有单独的.map文件源都指向脚本的ts版本。

webpack-dev-server命令输出：

我注意到它在[23-24]上构建了js文件，但是我不知道为什么，另外只运行webpack --debug会生成一个bundle.js.map文件，其源代码指向也是js文件。

这个问题已经困扰了我很长一段时间，所以如果它很简单，我道歉。

感谢您的帮助！

更新

问题可能是我在网络包装之前编译了ts吗？我试图在没有编译文件的情况下运行webpack，但现在找不到我的ts文件：

./app/main.ts
Module not found: Error: Cannot resolve 'file' or 'directory' ./modules/app.module in C:\--\app

  C:\--\app\modules\app.module doesn't exist

 @ ./app/main.ts 3:19-50

为什么不解析我的.ts文件？

Answer 1

发现了这个问题。

在我的package.config “扩展名”内应该是“扩展程序”，遗憾的是我没有错误指示语法问题。

Answer 2

正如您所说，错误在webpack.config.js内。从Webpack 2开始，当您有一个无效的配置对象时，它会给出错误消息，因此升级Webpack版本将帮助您将来避免这些问题。

如果您不想升级webpack，可以使用此软件包自动验证您的配置：https://github.com/js-dxtools/webpack-validator。

Webpack并非所有源图都显示打字稿
