function App(){
return(
    <Router>

            </Route>
            <Route path = "/login">
                {/* <Login/> */}
                <div>
                 <h1>this is login route</h1>
                </div>
            </Route>    
            <Route path = "/signup">
                <h1>signup page</h1>
            </Route>
            <Route path = "/contact">
                <h1>contact page</h1>
            </Route>
            <Route path = "/about">

Just add exact prop to all Route Component. It will work

<Route exact path='/yourpath' />
