【问题描述】：
我是 ionic 新手，试图获取一个用于调试的 apk，我在项目目录中使用了以下命令：
ionic cordova platform add android
我确实得到了“platforms/android”目录
然后我用了：
ionic cordova build android
这就是我所追求的：
ionic-app-scripts build --target cordova --platform android

Without `from` option PostCSS could generate wrong source map and will not find Browserslist config. Set it to CSS file path or to `undefined` to prevent this warning.

但我没有得到承诺的 \build\outputs\apk，有什么问题？
更新：我安装了 android studio 并更新了它，仍然得到 p>

更新：问题已解决，原来我的 java10 无法与 android 一起使用，只需安装 java8 即可解决问题
