The useHistory hook needs a routing context provided above it in the ReactTree. Move the HashRouter to wrap this Main component so it has a defined history reference to use.

示例:

import { HashRouter } from "react-router-dom";

...

<HashRouter>
  ...
  <Main />
  ...
</HashRouter>
import React from "react";
import { Route, Switch, useHistory } from "react-router-dom";
...

export default function Main(propss) {
  const history = useHistory();

  recognition.onresult = (event) => {
    const command = event.results[0][0].transcript;

    if (command.includes("navigate to") || command.includes("go to")) {
      if (command.includes("home") || command.includes("index")) {
        history.push("/home");
      } else if (command.includes("education") || command.includes("index")) {
        history.push("/education");
      } else if (command.includes("experience") || command.includes("index")) {
        history.push("/experience");
      } else if (command.includes("contact") || command.includes("index")) {
        history.push("/contact");
      }
    }
  };

  recognition.onend = () => {
    recognition.start();
  };

  if (settings.isSplash) {
    return (
      <div>
        <Switch>
          ...
        </Switch>
      </div>
    );
  } else {
    return (
      <div>
        <Switch>
          ...
        </Switch>
      </div>
    );
  }
}
