webpack打包时，路由懒加载没有生效，全部都打包到app.js中了

[Lxj96]

相同环境下，试了下别的项目，是可以分开打包的，但我这项目就不行。请问是什么原因导致的？ 这是vue.config.js配置 `'use strict' const path = require('path') const defaultSettings = require('./src/settings.js')

function resolve(dir) { return path.join(__dirname, dir) }

const name = defaultSettings.title || 'vue Admin Template' // page title

// If your port is set to 80, // use administrator privileges to execute the command line. // For example, Mac: sudo npm run // You can change the port by the following method: // port = 9527 npm run dev OR npm run dev --port = 9527 const port = process.env.port || process.env.npm_config_port || 9528 // dev port

// All configuration item explanations can be find in https://cli.vuejs.org/config/ module.exports = { /**
