I'm trying to use webpack-dev-server to run a simple program but I'm getting this error:
module.js:471
throw err;

Error: Cannot find module 'webpack'

I have installed webpack with following npm command
npm install --save-dev webpack
and I have the following configuration:
(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;
I have tried everything and I'm really lost. Does anyone have any idea?
npm install --save-dev webpack
is not enough.
You also have to install the following:
npm install --save-dev webpack-dev-server
And optionally, you can also install:
npm install --save-dev webpack-dev-middleware webpack-hot-middleware
