离子找不到平台

Ionic cant find platform

我在尝试使用 ionic Cordova build android 构建我的离子应用程序时遇到问题。 我已经用 ionic Cordova platform save 添加了平台,但 IONIC 似乎无法找到平台

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

这是 config.xml 文件

感谢任何帮助。

尝试先删除平台再添加 离子科尔多瓦平台 rm android 并再次添加 ionic cordova platform add android

问题:

ionic cordova platform save

Error : No Cordova platforms listed in config.xml. Nothing to prepare. That means your command not executed successfully to add the android platform.

管理 Cordova 平台目标

ionic cordova platform [<action>] [<platform>] [options]

例如

添加平台:您要添加的平台(android,ios)

 ionic cordova platform add ios
 ionic cordova platform add android

删除平台

ionic cordova platform rm ios
ionic cordova platform rm android

然后构建平台。

替代解决方案: 将此行添加到您的 config.xml 并构建 android 平台。

<engine name="android" spec="8.0.0" />

'spec' 取决于您的 android 平台要求

你可以做到

Remove platform if exist

ionic cordova platform rm android
ionic cordova platform add android
