我的配置文件有什么问题（OR ion cordova设置）;它无法找到任何平台，但我已经安装了ios，PLUS离子尝试添加和失败，因为它存在...以下示例来自模拟，同样的错误也由$ionic cordova platform add ios生成
$ ionic cordova emulate ios

You can save your installed platforms to config.xml with the ionic cordova platform save command.

Ionic无法找到该平台，因为<engine>中缺少config.xml标记。尝试稍微清理您的设置：
cordova platform rm ios（您可能会收到未添加平台的错误）platforms文件夹（如果该文件夹仍然存在）plugins文件夹，也可以删除package.json node_modules和package-lock.json 然后确保cordova和离子CLI是最新的：
(sudo) npm install -g cordova@latest ionic@latest
然后一步一步地恢复所有内容：
npm install cordova platform add ios@4.5.1 我个人喜欢只通过cordova CLI运行cordova命令，而不是通过离子CLI运行{当运行ionic cordova ...离子CLI时，只需将与cordova相关的命令转发到cordova CLI，这可能导致错误）。仅用于构建和运行应用程序，我使用组合命令，因为它更方便。
我还注意到您使用的是@ionic/app-scripts的旧版本，其中包含最新的ionic-angular版本。你也应该升级它。
