ios - react native 运行ios : The bundle identifier of the application could not be determined

Question

我正在使用 React-Native 并尝试构建一个 Hello-world 应用程序，但是，我仍然无法运行该应用程序。如果我运行 react-native run-ios，我会收到以下错误:...

Build system information
unexpected service error: The Xcode build system has crashed. Please close and reopen your workspace.

The following commands produced analyzer issues:

An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=22):
Failed to install the requested application
The bundle identifier of the application could not be determined.
Ensure that the application's Info.plist contains a value for CFBundleIdentifier.
Print: Entry, ":CFBundleIdentifier", Does Not Exist

Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/JustATributeApp.app/Info.plist
Print: Entry, ":CFBundleIdentifier", Does Not Exist

我发现很多主题都存在此错误，但没有一个能够解决该问题。

以下是一些附加信息:

react-native-cli: 2.0.1
react-native: 0.56.0
xcode 10.0 beta 2 (10L177m)

如何调试/修复此问题？

谢谢

Answer 1

错误消息的关键部分是确保应用程序的 Info.plist 包含 CFBundleIdentifier 的值。下面是我们解决此问题的方法。在 Xcode 中打开 yourprojectname.xcodeproj，然后检查“常规”选项卡下的包标识符。它应该有一个值(value)。我的是 com.yourprojectname.app.ios.triplets 。如果该字段为空，请将包标识符设置为某项。修改此字段将会更改您的 info.plist。
