这是Webpack的配置问题，我不确定如何调试。我有一个react-typescript项目。运行webpack失败并显示以下扩展错误消息：

我有这个package.json：

{

    "node-sass": "^4.7.2",
    "sass-loader": "^6.0.6",
    "webpack": "^3.10.0"
  }
}

这个webpack.config.js：

var path = require("path");
var config = {
    /* The entry point of the application. Webpack uses this information to create the dependency tree which is used to bundle the scripts.*/
    entry: ["./src/App.tsx"],
    /* This information is used to give the name of the bundled file and the location of the bundled file. */
    output: {
        path: path.resolve(__dirname, "build"),
        publicPath: "/build/",
        filename: "bundle.js"
    },
    /* The extensions which will be imported or required in the application scripts. */
    resolve: {
        extensions: [".ts", ".tsx", ".js"]
    },
    module: {
        /* Define the loaders to be used. Regex will test the type of files on which the loader is to be applied. The excluded files are also mentioned. Loaders are used mainly to preprocess/transpile the file when imported or required in the scripts before bundling. */
        loaders: [
            {
                test: /\.tsx?$/,
                loader: "ts-loader",
                exclude: /node_modules/
            },
            {
                test: /\.(jpe?g|png|gif|svg)$/i,
                loaders: [
                    'file-loader?hash=sha512&digest=hex&name=[hash].[ext]',
                    'image-webpack-loader?bypassOnDebug&optimizationLevel=7&interlaced=false'
                ]
            },
            {
                test: /\.css$/,
                loader: 'style!css!'
            }
        ]
    }
};
module.exports = config;

我的整个应用都存储在src/App.tsx和src/App.css。

我应该从哪里开始调试此问题？我认为我遗漏了package.json中的一些信息。

我不确定但您错过了主 //入口点 在package.json中， 这是执行NPM初始化时的第4个选项
