【问题描述】：

我的配置文件有什么问题（或 ionic cordova 设置）；它找不到任何平台，但我确实已经安装了 ios，PLUS ionic 尝试添加并失败，因为它存在......下面的示例来自 emulate，$ionic cordova platform add ios 也会生成相同的错误。

$ ionic cordova emulate ios
> cordova platform add ios --save
✖ Running command - failed!
[WARN] Platform already added. Saving platforms to config.xml.
> cordova platform save
✔ Running command - done!

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

这是我的 config.xml 文件：

感谢所有提示和提示！

【参考方案1】：

Ionic 找不到平台，因为config.xml 中缺少<engine> 标记。尝试清理一下您的设置：

运行cordova platform rm ios（可能会出现未添加平台的错误） 如果platforms 文件夹仍然存在，请将其删除 如果您希望重新安装 plugins 文件夹，也可以删除它们 删除package.json中所有与ios平台相关的引用 删除node_modules和package-lock.json

然后确保 cordova 和 ionic CLI 是最新的：

(sudo) npm install -g cordova@latest ionic@latest

然后一步步还原一切：

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ionic CLI（运行ionic cordova ... 时，ionic CLI 只是将cordova 相关命令转发到cordova CLI，这可能会导致错误）。只是为了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旧版本的@ionic/app-scripts 和最新的ionic-angular 版本。你也应该升级它。

【讨论】：

非常感谢！该应用程序现在通过 XCode 运行，但不直接从 Ionic CLI 运行：` > cordova emulate ios Error: Command failed: xcrun simctl list --json dyld: Library not loaded: /Library/Developer/PrivateFrameworks/CoreSimulator.framework/Versions/A /CoreSimulator 引用自：/Applications/Xcode.app/Contents/Developer/usr/bin/simctl 原因：找不到图像 [错误] 运行 cordova emulate ios 时出错（退出代码 1）。`

您可能需要将 XCode 和/或 XCode 命令行工具更新到最新版本。还要确保你不时重启你的mac，所以所有更新都不会被锁定:)

我正在运行 XCode 9.0（最新）。哦，离子服务也失败了。重新启动后会再试一次！ :)
