first of all, the navigation menu of ElementUI can be used normally. 
 now I"m going to make a login judgment. If you don"t log in, click "Security Center" and "Finance Center" in the navigation, and the interface will jump to the login screen 
 now the problem is that you can"t jump to the login interface 
 code is as follows. I hope you can solve the problem, or is there any other way 
handleSelect(key, keyPath) {
    //console.log(key,keyPath)keykeyPath
    const token = Cookies.get("loginToken");//token
    if(key === "safety" || key === "financial"){//safetyfinancial
    
        if (!token || token == "") {
            this.$router.push({path: "/login"});
            console.log(this.$route.path)// "/login" 
        }
    }
}
