Warning: Hash history cannot PUSH the same path; a new entry will not be added to the history stack

问题

I'm working on react-router-dom and in console this error is appearing.

Warning: Hash history cannot PUSH the same path; a new entry will not be added to the history stack

回答1:

Basically, the problem is that if you are on page /here and click a link to /here, you end up with essentially duplicate (just different keys) location objects. Please confirm that your pushing the different paths in <Link to='/diff'/>

回答2:

Use Replace

add 'replace' to the NavLink or Link

<NavLink exact to="/myProfile" replace >My Propile</NavLink>

or

<Link to="/myProfile" replace />

I got this message. I change the routing variable to function

before message:

    const routing = (
      <Switch>
        ...
      </Switch>
    );

fixed to:

    const routing = () => (
      <Switch>
        ...
      </Switch>
    );
