在 Android 上运行 Expo 项目时出错：BuildConfig 和 R 的“找不到符号”;“反应原生”：“0.72.6”

问：

你好 Stack Overflow 社区！

尝试使用 expo run：android 命令在 Android 上运行我的 Expo 项目时，我遇到了一个问题。我遇到以下编译错误：

FAILURE: Build failed with an exception.

我尝试更改“react-native”的库版本并清除“gradlew clean”我的 android 缓存并再次执行“expo run：android”。

编译器无法找到由 Gradle 构建过程生成的 BuildConfig 类。 编译器找不到“R”包。

我查看了其他类似的案例，他们建议我更改库的版本，但这并没有解决我的问题！

在查看错误消息时，我注意到这些问题与缺少符号 BuildConfig 和 R 有关。我相信这些资源应该可用，但编译器无法找到它们。

您能就如何解决这个问题提供建议吗？我使用 Expo 来初始化项目，直到现在一切都很好。也许有人遇到过类似的问题，可以分享他们的经验或提出解决方案？

值得一提的是，我在 Ubuntu 22 上运行它。

提前感谢您的帮助！
