Question

我目前正在开发一个简单的订单应用程序，它可以在开发中正常运行，但是如果我从构建安装 apk 或通过 Expo Client 在生产模式下运行应用程序，我会收到此错误：

TypeError: (0,f.useState) is not a function. (In '(0,f.useState)(!0)', '(0,f.useState)' is undefined)

我当前的配置是：

expo-cli：4.0.17
expo-sdk: 40.0.1 (react-native 0.63.3)
反应：16.13.1
反应域：16.13.1

此错误不会在启动时发生，而是在我到达特定页面时发生。在阅读了大量关于 TypeError: (0,f.useState) is not a function 的 QA 后，我迄今为止尝试过的事情：

重新安装 node_modules，清除 npm 缓存，删除观察者。
使用 React.useState 而不是 useState。
在世博论坛上寻求帮助。

有人知道如何解决这个问题吗？或者我可以尝试什么使它起作用？问候！

Answer 1

我在没有 --minify arg (expo start --no-dev) 的情况下在 prod 模式下运行应用程序，并且我能够解决这个问题。

调试我发现自动完成从导致此问题的另一个 React 实例导入了 useState。

希望这可以帮助任何有此问题或类似问题的人。
