Webpack错误/Users/anthonymakela/Desktop/Projektit/Clonebnb-master2/config/webpack/development.js

尝试运行任何webpack命令时出现此错误 . 这个应用程序的回购是在https://github.com/markpassando/Clonebnb

Webpack配置/Users/anthonymakela/Desktop/Projektit/Clonebnb-master2/config/webpack/development.js未找到，请运行'bundle exec rails webpacker：install'以使用默认配置安装webpacker或为您的自定义添加缺少的配置文件环境 .

另外，当运行bundle exec时，它会显示这个

错误：命令'webpacker：install'无法识别

这是我的webpack.config.js

var path = require("path");
var webpack = require("webpack");

var plugins = []; // if using any plugins for both dev and production
var devPlugins = []; // if using any plugins for development

var prodPlugins = [
new webpack.DefinePlugin({
'process.env': {
  'NODE_ENV': JSON.stringify('production')
}
}),
new webpack.optimize.UglifyJsPlugin({
compress: {
  warnings: true
}
})
];

plugins = plugins.concat(
process.env.NODE_ENV === 'production' ? prodPlugins : devPlugins
)

module.exports = {
context: __dirname,
entry: "./frontend/clone_bnb.jsx",
output: {
path: path.resolve(__dirname, 'app', 'assets', 'javascripts'),
filename: "bundle.js"
 },
plugins: plugins,
module: {
loaders: [
  {
    test: [/\.jsx?$/, /\.js?$/],
    exclude: /node_modules/,
    loader: 'babel-loader',
    query: {
      presets: ['es2015', 'react']
    }
    }
    ]
    },
    devtool: 'source-maps',
    resolve: {
     extensions: [".js", ".jsx", "*"]
    }
    };

这是package.json
