我有一个具有以下结构的微前端应用程序。我正试图将营销和公司安装到容器中，但不断获得无效的钩子调用。它们都使用react 18.2, react-dom 18.2和react-router-dom 6.3.0。营销本身在浏览器中加载良好，但当试图将其加载到容器中时，我得到一个无效的钩子调用警告。发生了什么事?我可以在容器(主机)和营销(远程)中的BrowserRouter中使用Router吗?

// if given a default history object, assign it to history; otherwise use MemoryHistory object
const history = defaultHistory || createMemoryHistory();
if (onNavigate) {
history.listen(onNavigate); // event listener tied to the history object which listens to whenever navigation occur
}
const root = ReactDOM.createRoot(el);

……
shared: {...packageJson.dependencies, ...packageJson.peerDependencies}
和警告消失
