我在尝试使用ionic Cordova build android构建离子应用程序时遇到问题。
我已经用ionic Cordova platform save添加了平台，但是IONIC似乎找不到该平台

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

尝试先删除平台，然后再次添加 离子科尔多瓦平台rm android 并再次添加ionic cordova平台并添加android
答案 1 :(得分：0)
问题：
ionic cordova platform save
错误：config.xml中未列出Cordova平台。没什么准备这意味着您的命令无法成功执行以添加android平台。
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
用于删除平台
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config.xml中并构建android平台。
<engine name="android" spec="8.0.0" />
“规范”取决于您的android平台要求
答案 2 :(得分：0)
可以做到
删除平台（如果存在）
ionic cordova platform rm android
ionic cordova platform add android
