defaultWebpagePreferences error while building ios build for ionic 5 code

Question

我正在尝试为 ionic 5 应用程序构建 ios 版本，但我在构建应用程序时在我的应用程序中遇到此错误。我在互联网上寻找解决方案，但似乎没有任何效果

Answer 1

您的 Xcode 版本可能是您的 Cordova iOS 平台不支持的版本。如果您降级 cordova-ios 平台版本，它应该可以工作。不过，我强烈建议尽可能更新您的 Xcode。

此更改是在版本 6.1.0 中引入的。在此处检查提交：https://github.com/apache/cordova-ios/commit/440fc0fe01dabbccfd703ac7854fd24b0b88e1b5

这意味着使用 ios 平台的版本 6.0.0 可能有效。安装：

cordova platform rm ios
cordova platform install ios@6.0.0

但是这个版本在 cordova-ios 的后续补丁版本中解决了其他问题。
