尝试ionic cordova build android --release之后
我收到以下错误：
Data path ".builders['cordova-build']" should have required property 'class'.
该应用程序可在浏览器中的ios和android中通过模拟运行的方式提供给Ionic Labs，但在发行版本中无法运行。 我已经按照堆栈上的其他答案将“ @ angular-devkit / build-angular”更改为许多不同的版本，但无济于事。 这是一个现有的角度应用程序，我需要将其包装在Ionic中以用于本机ios / android，因此我尝试确保所有依赖项都兼容。

在环境变量中添加以下信息。 _JAVA_OPTIONS = -Xmx512M
更新以下软件包， “ @ ionic / angular-toolkit”：“ ^ 1.5.1” =>对于Angular 7 “ @ ionic / angular-toolkit”：“ ^ 2.0.1”，=>对于Angular 8
