Question

我在IOS项目中构建React Native应用时遇到了这样的错误：

遇到
处理命令（domain = NSPOSIXErrorDomain， code = 2）打印：输入，＆＃34;：CFBundleIdentifier＆＃34;，不存在

我在GitHub中读到关于那个issues的帖子，但是没有找到可以解决我问题的解决方案。任何想法如何解决它？

Answer 1

原因可能是您有一些来自以前版本的版本文件导致了问题。

清除ios/build/your_project以触发新的构建

Answer 2

就我而言，原因是-构建文件名为MyMob.app，但它尝试安装到模拟器的应用程序是mymob.app。

我通过更改mymob.xcscheme:46中的行来解决了

BuildableName = "MyMob.app"

BuildableName = "mymob.app"

日志为

iinfo Installing "build/mymob/Build/Products/Debug-iphonesimulator/mymob.app"
An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2):
Failed to install the requested application
An application bundle was not found at the provided path.
Provide a valid path to the desired application bundle.

error Failed to launch the app on simulator, An error was encountered processing the command (domain=FBSOpenApplicationServiceErrorDomain, code=4):
The request to open "com.mymob.app" failed.

        The operation couldn't be completed. Application info provider (FBSApplicationLibrary) returned nil for "com.mymob.app"
        Application info provider (FBSApplicationLibrary) returned nil for "com.mymob.app"

处理命令时遇到错误（domain = NSPOSIXErrorDomain，code = 2）
