Expo 应用程序在开发模式下运行良好，但在生产模式下崩溃

Question

我目前正在开发一个简单的订单应用程序，该应用程序在开发中工作正常，但如果我从构建安装 apk 或通过 Expo Client 在生产模式下运行该应用程序，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（反应原生0.63.3）
• 反应：16.13.1
• react-dom：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，我到目前为止尝试过的事情：

• 重新安装node_modules，清除npm缓存，删除观察者。
• 使用

  React.useState

  代替

  useState

  。
• 在博览会论坛上查看帮助。

有人知道如何解决这个问题吗？或者我可以尝试什么让它发挥作用？ 问候！

Answer 1

我在生产模式下运行应用程序，没有

--minify

arg

(expo start --no-dev)

，我能够解决这个问题。

调试时我发现自动完成从 React 的另一个实例导入了

useState

，导致了这个问题。

希望这对遇到此问题或类似问题的人有所帮助。

Answer 2

只需运行命令

npm i react-native-screens
