我也尝试过 expo 弹出，然后运行 npx react-native run-android 错误，我又遇到了同样的错误。

反应原生版本：0.63.4

有人想解决这个问题吗？

【问题讨论】：

文字com.mapsabad.profishop.从何而来？这是您指定的值。它显然不应该在末尾有.，所以找到你指定值的位置，并删除.，然后问自己为什么首先在其中放置一个句点。

标签： java react-native gradle expo

【解决方案1】：

从com.mapsabad.profishop. 中删除尾随句点，因为日志在多个地方表明这是一个错误。

【解决方案2】：

就我而言，这是因为我在 ReactNativeFlipper 的包名称中包含“native”一词。认为它是从我的 app.json Expo 文件中的名称字段复制而来的。当我打开文件时，“native”这个词甚至被标记为红色文本，所以我通过重命名来解决它。
