ios - 运行子流程cordova时出错，但没有解释

Question

我正在使用ionic cordova build --prod --release为iOS编译我的 ionic Angular 构建，并且出现此错误:

编辑:我用--verbose重新运行命令，这是我得到的结果:

This app does not have additional resource files defined
Prepared iOS project successfully
No scripts found for hook "after_prepare".
No scripts found for hook "before_compile".

        cordova build ios --release --verbose exited with exit code 1.

        Re-running this command with the --verbose flag may provide more information.
  ionic:utils-process onBeforeExit handler: 'process.exit' received +0ms
  ionic:utils-process onBeforeExit handler: running 2 functions +0ms
  ionic:utils-process processExit: exiting (exit code: 1) +36ms

从字面上看，这是错误的全部，而且我找不到离它很近的东西。有任何想法吗？

检查您的cordova ios版本
如果它是5. +，则删除您的构建并使用

ionic cordova build ios@latest
