No QueryClient set, use QueryClientProvider error occurred even though QueryClient set and use QueryClientProvider were specified.enter image description here

未设置QueryClient,即使指定了QueryClient Set和Use QueryClientProvider,也出现了Use QueryClientProvider错误。


After a certain period of time in the above state, sometimes normal components are displayed again, and sometimes a blank screen appears.

在上述状态下,经过一段时间后,有时会再次显示正常组件,有时会出现空白屏幕。

import { routes } from "./routes";
import { QueryClientProvider } from "@tanstack/react-query";

const App = () => {
const elem = useRoutes(routes);
const queryClient = getClient();
return (
<QueryClientProvider client={queryClient}>
{elem}
<ReactQueryDevtools initialIsOpen={false} />
</QueryClientProvider>
);
};
export default App;

I tried running your code online with exact same dependency versions, and it is working just fine. Your dependency tree might be incorrectly resolved. Deleting and reinstalling node_modules might fix the issue. And, I also believe you no longer need v3 react-query since you're already using v4 @tanstack/react-query.

我试着用完全相同的依赖项版本在线运行您的代码,它运行得很好。您的依赖关系树可能未正确解析。删除并重新安装NODE_MODULES可能会解决该问题。而且,我也相信您不再需要v3的REACT-QUERY,因为您已经在使用v4@TANSTACK/REACT-QUERY了。
