運行子進程cordova時出錯，但沒有解釋

Question

我正在使用ionic cordova build --prod --release for iOS 編譯我的 ionic angular build，但出現此錯誤：

編輯：我用 --verbose 重新運行我的命令，這是我得到的結果：

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".
Cannot read property 'toLowerCase' of undefined

        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

這實際上是錯誤的全部，我找不到任何與之相近的東西。 有任何想法嗎？

檢查您的cordova ios版本如果它是les then 5.+然后使用刪除您的構建和重建

ionic cordova build ios@latest
