我收到Warning: componentWillReceiveProps has been renamed，但是我没有看到任何可以调用的方法。
错误堆栈在这里-它始于在setState中调用componentDidMount的时候，我认为这样做是可以的：
Warning: componentWillReceiveProps has been renamed, and is not recommended for use.
See https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html for details.
* Move data fetching code or side effects to componentDidUpdate.
* If you're updating state whenever props change, refactor your code to use memoization techniques or
move it to static getDerivedStateFromProps. Learn more at: https://reactjs.org/blog/2018/06/07/you-probably-dont-need-derived-state.html
* Rename componentWillReceiveProps to UNSAFE_componentWillReceiveProps to suppress this warning in non-strict mode.
In React 17.x, only the UNSAFE_ name will work.
To rename all deprecated lifecycles to their new names,
you can run `npx react-codemod rename-unsafe-lifecycles` in your project source folder.

正如您在问题的注释中意识到的那样，此警告来自TreeNode的一部分react-lazy-tree。
如果要摆脱它，您有两种解决方法：
