使用 create-expo-app 錯誤創建的 Expo 項目

Question

使用create-expo-app的 Expo 項目在使用expo start命令運行時會導致捆綁錯誤。 我在 iOS（模擬器和物理設計）上使用 Expo Go。

空白項目和使用-t expo-template-blank-typescript標志和參數創建的 typescript 項目都會發生這種情況。

其中一個依賴項顯然找不到expo-constants模塊。

我有同樣的問題，沒有合適的解決方案，但這可以作為一種解決方法。 在expo start之前運行它。

expo install expo-constants expo-file-system expo-modules-core
