我尝试过多种模式，如下所述。

\n

\n
• 清理构建文件夹>>重建。
\n
• 删除 pod 和 podfile.lock >> pod install。
\n
• 删除派生数据>>清理构建文件夹>>重建。
\n
• 关闭 xCode >> rm -rf ~/library/developer/xcode/衍生数据 >> rm -rf ~/.rncache >> rm -rf node_modules && npm install && cd ios && rm -rf Pods && pod install && cd ..

在进行上述试验之前，我还重新启动了系统。我在项目中使用了 swift。\n请为此提供一个正确的解决方案。

Answer 1

我通过执行 \xe2\x8c\x98+Shift+K 并重建解决了不同包的类似问题。

Answer 2

对于这个特定的依赖项（react-native-linear-gradient），修复位于https://github.com/react-native-linear-gradient/react-native-linear-gradient/pull/500但尚未发布然而（当我写这篇文章时）。

react-native-linear-gradient你应该像这样从 git指定版本

package.json

  "react-native-linear-gradient": "https://github.com/react-native-linear-gradient/react-native-linear-gradient#0e3af58",

然后运行 ​​npm/yarn install，清理你的构建并重试。
