useRequest Warning: Can't perform a React state update on a component that hasn't mounted yet.

[mao437303994]

这个问题没人遇到吗？获取到数据之前组件已经被卸载了，内部依旧调用useUpdate()导致报错

[liuyib]

React has removed this warning in v18, please see: reactwg/react-18#82

In React < v18, please ignore this warning.

React 18.2.0 并没有解决

来给个 demo ？具体问题具体分析

[liuyib]

截图的报错和 reactwg/react-18#82 里的报错：

Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.

好像不是同一个问题，后面再看下

@1zilc 多谢提供 demo，但是没有复现

React 18.3.3 在使用 useRequest 也遇到了一样的问题
const { data: areaOptions } = useRequest(async () => await GetAreaList(), { cacheKey: 'cacheKey-area-list' });

好像是设置了 cacheKey 就会有这个问题

确认，设置了cacheKey就会有问题，注释掉就没问题。React 18.2.0
