ios - ionic 找不到平台

Question

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，相同的错误是由 $ionic cordova platform add ios 生成的以及。

$ ionic cordova emulate ios
> cordova platform add ios --save

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

这是我的 config.xml 文件:

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

运行 cordova platform rm ios (可能会报错说没有添加平台)

删除 platforms文件夹(如果它仍然存在)

也许也删除 plugins文件夹，如果你想重新安装它们

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

我个人喜欢运行cordova命令只是通过cordova CLI而不是通过ionic CLI(运行时ionic cordova ... 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与最新 ionic-angular版本。你也应该升级这个。
