可重现的演示

错误如下：

[!] CocoaPods could not find compatible versions for pod "UMCore":
  In Podfile:
    UMCore (from `../node_modules/@unimodules/core/ios`)

    UMPermissionsInterface (from `../node_modules/unimodules-permissions-interface/ios`) was resolved to 5.4.0, which depends on
      UMCore

Specs satisfying the `UMCore (from `../node_modules/@unimodules/core/ios`), UMCore` dependency were found, but they required a higher minimum deployment target.

复制步骤

npm install --save react-native-unimodules 按照此处的步骤操作：https://docs.expo.io/bare/installing-unimodules/ 在ios目录下安装pod

预期行为与实际行为

预期的行为是 pod install 没有任何错误，但会收到 Reproducible Demo 部分中显示的错误。

【参考方案1】：

这个问题是因为库UMCore pod 文件的开发目标大于你项目的开发目标。要解决此问题，请查找 UMCore 库的 pod 文件并检查 s.ios.deployment_target 的值。如果价值开发目标大于您的项目开发目标，则为您的项目开发目标设置相同的目标值。

要更改您的项目开发目标，请在 xcode 中打开项目。从 xcode 常规选项卡 > 部署信息。在这里你可以改变。
