我似乎无法让 webpack-dev-server 让 webpack2 工作。

我正在使用以下版本： webpack@2.1.0-beta.25&webpack-dev-server@2.1.0-beta.10

我得到以下 CLI 日志：

webpack: bundle is now VALID.

我的webpack.config.js文件如下所示：

const path = require( "path" );
const merge = require( "merge" );
const htmlWebpackPlugin = require( "html-webpack-plugin" );
const parts = require( "./webpack.config.parts" );
const PATHS = {
    app : path.join( __dirname, "app" ),
    build : path.join( __dirname, "build" )
};

const common = {
    entry : {
        app : PATHS.app + "/index.js"
    },
    output : {
        filename : "run.build.js",
        path : PATHS.build
    },
    resolve : {
        alias : {
            components : path.resolve( __dirname, "app/components" )
        },
        extensions : [ "js", "jsx" ]
    },
    devServer : {
        contentBase : PATHS.app
    },
    module : {
        rules : [
            {
                test : "/\.jsx?$/",
                use : [
                    {
                        loader : "babel-loader",
                        options : {
                            presets : [
                                "react",
                                "es2015"
                            ]
                        }
                    }
                ]
            }
        ]
    },
    plugins : [
        new htmlWebpackPlugin({
            title : "!!! testing webpack2 !!!"
        })
    ]
};

var config;    
switch( process.env.npm_lifecycle_event ){
    case( "buildProd" ):
        config = merge( common,
                             {} );
    case( "startDev" ):
    default:
        config = merge( common,
                             {
                                 devServer : {
                                     contentBase : PATHS.app
                                 }
                             });
}
module.exports = config;

我错过了什么？

解决方案是将--no-inline选项传递给package.json. 因此，在 中package.json，scriptsobj 将是：

"scripts" : {
    "startDev" : "webpack-dev-server --no-inline"
}

https://webpack.js.org/configuration/dev-server/#devserver-inline-cli-only

真正的问题是您extensions内部的密钥resolve（webpack 配置）设置错误。

错误的

extensions : [ "js", "jsx" ]

正确的

extensions : [ ".js", ".jsx" ]

检查 https://github.com/webpack/webpack-dev-server/issues/720或https://webpack.js.org/configuration/resolve/

我正在使用不同的设置，但得到了相同的错误（几乎）。我认为这--no-inline只是一种解决方法。
