Components do not work at startup, how to fix it?

Question

JavaScript

file:///D:/aa/dist/index.html I run the file, the green background appears, and my components in the route do not work, although everything works as it should in localhost: 8080 , what could be the reason?

<div className="game">
      <Switch>
        <Route exact path="/" component={Start} />
        <Route path="/game" component={Game} />
        <Route path="/finish" component={Finish} />
      </Switch>
    </div>

the div with the class is shown, but inside it is empty

The file url protocol does not have a sub-path in the file. You cannot write D:\Dir\file.txt\ahaha\ in Windows, so routing cannot work there, except perhaps based on location.hash
