2 years ago umi-plugin-keep-alive 是需要的，可以换从 react-activation 导出试试，另外需要看你是如何使用 KeepAlive 插件的，看报错可能是渲染了一个 undefined

请教 umi一定要用这个插件么，如果不用是否有推荐方案 或 项目使用了umi-plugin-keep-alive 那我有个npm包需要用到keepAlive，它是从umi导入还是从react-activation npm包安装了一下两个库 "umi": "^3.2.10", "umi-plugin-keep-alive": "^0.0.1-beta.34",
我发现两种都会导致缓存无效，从umi import的时候 npm包里面的代码ts会提示umi没有导出useAliveController 和KeepAlive元素，代码如下 import { KeepAlive, useAliveController } from 'umi';
改成 // @ts-ignore import { KeepAlive, useAliveController } from 'umi';
打包不报错，但是运行项目后，无法执行，报错如下 umi.deb8c82b.js:325505 Uncaught Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
react_devtools_backend.js:4026 The above error occurred in the component:
