关于vuex设置？

store/index.js
`export const state = {
a: 0
}

export const mutations = {
add (state) {
state.a++
}
}`

npm run dev 后提示：

请问使用状态树的模块化方式，是否需要配置其他地方呢？
一直在网上找demo，只有你的使用了这个模块化方式，我自己测试也不ok！
求教！

这个礼拜内会更新，nuxt 和 vuex升级导致的

官方文档错误，状态树的模块化方式也是改成promise，需要一个返回值

export const state = () => ({ a: 0 })

name =()=> 用箭头函数搞定

感谢已解决！

最新版是需要返回一个func，而不是一个obj

你应该是是升到了A版本，建议暂时不要升级，等1.0出正式版再做重构，项目刚升级到0.10.7了。
