vue项目 打包 报错

Question

打包时报这个错，有知道怎么解决的吗？
同事打包又不会，是和我电脑全局包的版本有关吗？

router.js

import Vue from 'vue'
import Router from 'vue-router'

const _import = require('./_import_' + process.env.NODE_ENV)

Vue.use(Router)

export const routes = [{
    path: '*',
    redirect: '/'
}, {
    // dev 登陆
    path: '/login',
    name: '/login',
    component: _import('login/index')

const router = new Router({

    base: '/',
    scrollBehavior: () => ({
        x: 0,
        y: 0
    }),

export default router

_import_production.js

module.exports = file => () => import('@/views/' + file + '.vue')

_import_development.js

module.exports = file => require('@/views/' + file + '.vue').default

Answer 1

import 是静态执行,不能使用表达式和变量 报错就在这一句

module.exports = file => () => import('@/views/' + file + '.vue')

你全部改成后面一种方式试试
