我迁移我的expo项目以响应本机项目。我删除了expo,并尝试使用本机方式添加初始屏幕和推送通知以及添加没有expo的字体。我还安装了没有博览会的本机反应导航。我使用android studio和Xcode运行该项目。我有一些问题,但我通过修复package.json文件中的某些软件包版本来解决现在我得到这个错误:
Warning: componentWillReceiveProps has been renamed, and is not recommended for use. See ... 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: ***
* 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.

在您的情况下,实际上这不是错误。这是来自本地响应的警告。
componentWillReceiveProps是一个同步钩子。在设置新道具和数据完成加载之间,需要在此挂钩内调用异步函数(如数据获取),以进行渲染。
因此,componentWillReceiveProps
已被弃用,原因如下:因此,我建议您尽可能使用componentDidUpdate挂钩并更新代码。
