webpack-dev-server找不到模块“ webpack”

我正在尝试使用webpack-dev-server运行一个简单的程序,但出现此错误:

module.js:471

throw err;

^

Error: Cannot find module 'webpack'

at Function.Module._resolveFilename (module.js:469:15)

at Function.Module._load (module.js:417:25)

at Module.require (module.js:497:17)

at require (internal/module.js:20:19)

at Object.<anonymous>

at Module.load (module.js:487:32)

at tryModuleLoad (module.js:446:12)

at Function.Module._load (module.js:438:3)

我已经使用以下npm命令安装了webpack

npm install --save-dev webpack

并且我有以下配置:

(webpack.config.js)

var webpack = require('webpack');

var path = require('path');

var BUILD_DIR = path.resolve(__dirname, 'client/public');

var APP_DIR = path.resolve(__dirname, 'client/app');

var config = {

entery: APP_DIR + '/index.js',

output: {

path: BUILD_DIR,

filename: 'bundle,js',

},

module: {

loaders: [

{

test: /.jsx?$/,

loader: 'babel-loader',

exclude: /node_modules/,

query: {

presets: ['es2015', 'react']

}

}

]

}

};

module.exports = config;

我已经尝试了一切,但我真的迷路了。有人有什么主意吗?

回答:

npm install --save-dev webpack 是不足够的。

您还必须安装以下内容:

npm install --save-dev webpack-dev-server

另外,您还可以安装:

npm install --save-dev webpack-dev-middleware webpack-hot-middleware
