VueX Vue: Could not find a declaration file for module vuex.

vuex4.0.2 webstorm报如下错误
Vue: Could not find a declaration file for module vuex.


解决办法
在src目录下新建一个vuex.d.ts
文件内容如下

declare module "vuex" {export * from "vuex/types/index.d.ts";export * from "vuex/types/helpers.d.ts";export * from "vuex/types/logger.d.ts";export * from "vuex/types/vue.d.ts";
}

再回来，就不会报错了
