vue 异步组件采用参数路径报错
vue在异步加载组件时如下
var name = '../components/AdminHome/UserManager.vue';var component = () => import(name);
import传入一个参数时会报错:
client?cd17:147 ./src/store/index.js67:31-43 Critical dependency: the request of a dependency is an expression

}
Reason: Error: Cannot find module '../components/AdminHome/UserManager.vue'.
如果是这样直接用字符串就不会有问题:
var component = () => import('../components/AdminHome/UserManager.vue');
回答:
var name = 'components/AdminHome/UserManager.vue';var component = ()=>import(`@/${name}`)
暂时找到办法了,这样却可以正常加载,到时候找到具体原因再来更新
回答:
楼上有误。import()函数是可以动态载入模块的,import才不支持动态载入。试一下将
var name = '../components/AdminHome/UserManager.vue';var component = () => import(name);
改成
var name = '../components/AdminHome/UserManager.vue';var component = () => import(`${name}`);
可能是import()函数的参数不能是表达式,上面修改后参数就是字符串了,并且能动态加载。
回答:
这个可能是import的限制, 不是vue-cli的问题, 不允许动态载入模块, 具体出处没有找到, 我在找找, 但是可以肯定在这个教程中有提到, 你先看下

你好,我遇到了同样的问题。但是我按上述方法都没有得到解决方案,请问有没有什么别的办法呀?
回答:
如果组件都在components文件夹下按下图做

感谢 @佘贞标
楼主可以参考import的部分,实现路由懒加载
var routes_config = [{ path: '/sider',
component_path: './pages/manage/index.vue'
}, {
path: '/user',
component_path: './components/test.vue'
}]
// 将全局路由进行注册
var routes = {
routes: (function() {
var list = new Array()
for (let i in routes_config) {
list.push({
path: routes_config[i].path,
component: () =>
import (`${routes_config[i].component_path}`)
// component: httpVueLoader(routes_config[i].component_url)
// 异步组件
// component: function(resolve, reject) {
// // 异步请求组件配置
// axios.get(routes_config[i].component_url).then(response => {
// resolve({
// // response.data = "<h1>User</h1>"
// template: response.data
// })
// })
// }
})
}
return list
})()
}
