Webpack 未找到模块：错误：无法解析模块'；服务器'；

我尝试使用webpack来管理项目中的文件。我使用webpack开发服务器和bower webpack插件。运行服务器时，浏览器控制台中出现错误

未找到模块：错误：无法解析模块“服务器”

webpack.config.js

const BowerWebpackPlugin = require("bower-webpack-plugin");

module.exports = {
    entry: './src/script/index.jsx',
    output: {
        filename: 'bundle.js', //this is the default name, so you can skip it
        //at this directory our bundle file will be available
        //make sure port 8090 is used when launching webpack-dev-server
        publicPath: 'http://localhost:8090/assets'
    },
    devtool: 'source-map',
    module: {
        loaders: [
            {   
                test: /\.js[x]?$/, 
                loaders: ['react-hot', 'jsx', 'babel'],
                exclude: /node_modules/ 
              },
              {
                test: /\.scss$/,
                loaders: [ 'style', 'css?sourceMap', 'sass?sourceMap' ]
              }
        ]
    },
    plugins: [
        new BowerWebpackPlugin()
    ],
    externals: {
        //don't bundle the 'react' npm package with our bundle.js
        //but get it from a global 'React' variable
        'react': 'React'
    },
    resolve: {
        extensions: ['', '.js', '.jsx'],
        modulesDirectories: ["./src", "node_modules", "bower_components"]
    }
}

编辑：现在我使用不带bower的网页包插件

在源文件或第三方库的某个地方，有一个对名为

server

（不带任何扩展名）的资源的引用。它可以是

require（'server'）

的形式。Webpack正在尽最大努力找到它。它在不同的位置检查不同形式的It（例如，

server

作为目录，

server.js

，

server.jsx

，等等），但最终失败。尝试找出此引用的位置。

我在使用webpack dev server时遇到类似错误。尽管Web包是在全球范围内安装的，但我必须将其作为项目的一部分进行安装，以解决“Web包/热/开发服务器”依赖性问题。

在错误地使用

npm启动服务器

而不是

npm运行服务器

时遇到类似错误

如果您的

包.json中有
server
脚本，运行
npm run server
将启动它。
如果使用
npm启动服务器
，它将在源代码中查找
服务器
模块并尝试启动它

小的打字错误，但由于缺乏注意，可能很容易发生。
我的情况是，我在使用TFS和webpack时，发现许多
模块未找到
错误

原来我的
package.json
文件中有一个不存在的包，我没有删除它

"primeng": "1.0.0-rc.4",
"primeng-ultima": "Unavailable"

我一删除这个软件包，一切都正常了

幸运的是，日志让我得出了这个结论。发生的事情是，npm在无法下载此软件包时跳过了其他软件包的恢复。
这基本上就是webpack所说的。。。找不到名为serverOne的模块/文件。我也有同样的问题，但当我不使用webpack时，只需在html中包含一个脚本一个脚本，就可以了。当我使用webpack时，会显示此错误。在代码中，它需要一个webpack无法找到的模块，正如您所说的，但我的疑问是为什么我以正常的html方式包含脚本。我知道我必须npm安装模块，这将解决问题，但idkk为什么它不起作用。我尝试了我，但这没有帮助。听起来有点像naf，必须同时安装全局和每个项目。我希望开始看到一些节省时间的东西，因为网页对我来说就像是在浪费时间。。。
