BUG:Error: Invalid navigation guard或The "next" callback was never called inside of :

错误代码：

router.beforeEach(async (to, from, next) => {
    NProgress.start()
    const token = store.getters.token;
    debugger
    if (whiteList.indexOf(to.path) !== -1) {
        next()
    } else {
        ...
        } else {
            next(`/login?redirect=${to.path}`)
            NProgress.done()
        }
    }
});

原因分析：多加了一个async，去掉即可。
