这是我的webpack/development.js文件：

process.env.NODE_ENV = process.env.NODE_ENV || 'development'

const environment = require('./environment')

module.exports = environment.toWebpackConfig()

这是我的webpack/production.js文件

process.env.NODE_ENV = process.env.NODE_ENV || 'production'

const environment = require('./environment')

module.exports = environment.toWebpackConfig()

这是我的webpack/environment.js文件：

const { environment } = require('@rails/webpacker')

module.exports = environment

这是我的app/javascript/packs/application.js文件：

import "controllers"
const images = require.context('../images', true)
const fonts = require.context('../fonts', true)
