在模拟器中运行项目出错：“打印：条目”：CFBundleIdentifier“，不存在”

我正在我的笔记本电脑中设置React-Native . 我用于不同工具的版本如下：Node.js：v10.7.0 react-native-cli：2.0.1 react-native：0.56.0

在运行命令“react-native run-ios”时，我收到如下错误：

The following build commands failed:

    CompileC /Users/mshikher/Documents/react-native-workspace/firstProject/ios/build/Build/Intermediates/React.build/Debug-iphonesimulator/React.build/Objects-normal/x86_64/RCTShadowView+Internal.o Views/RCTShadowView+Internal.m normal x86_64 objective-c com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)

Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/firstProject.app/Info.plist

我在StackOverflow中尝试了很多答案，但到目前为止还没有任何工作 . 这可能是背后的问题 .

我最近得到的错误是：
