无法直接在iPhone上运行react-native应用程序（部署目标错误）

问题

当我在模拟器中运行react-native时，它工作正常。我现在尝试在直接连接到 MacBook 的 iPhone 上运行它，但出现了问题。有几个警告说Deployment Target is set to 7.0.

这个具体是在哪里设置的呢？它是在我正在使用的库中设置的吗？我该如何解决这个问题？

我发现似乎与此问题不重复的类似信息包括：

• 对模拟有问题的人（刺激器对我来说工作正常）
• 建议人们在 XCode 中使用 Legacy Build 系统（其他人认为这不是一个好主意）。

那么，到底是什么导致了这个问题？我该如何解决它，以便我可以在我的物理 iPhone 设备上运行该应用程序？

问题？

React Native 似乎只支持 7.0 的部署目标。但是，新版本的 XCode 不再将 7.0 作为目标选项。新版本 XCode 的最低目标是 8.0。

遗留构建？

我看到的一些问题表明我可以使用旧版本来代替。但是，我想知道这是否会导致任何其他问题。

我认为问题在于开发团队：

构建系统信息 错误：签署“TestAppApp07Tests”需要开发团队。在项目编辑器中选择一个开发团队。 （在目标“TestAppApp07Tests”中）

构建系统信息错误：签署“TestAppApp07”需要 开发团队。在项目编辑器中选择一个开发团队。 （在 目标“TestAppApp07”）

只需组建一个有效的开发团队即可。如果您没有，请创建它。设置正确的开发团队后，它应该可以工作。

确保为这两个目标设置团队：TestAppApp07 and TestAppApp07Tests

关于部署目标：

如果与部署目标相关的问题与一些旧的依赖项有关，我认为您可以使用旧版构建系统。

据我所知，Xcode 8 或更高版本不支持部署目标 iOS 7.0。
