科尔多瓦要求失败

Question

刚开始学cordova，过不了requirements step.

Cordova v7.0.1

Android Studio 2.3.3

我完全不确定我该怎么做。我认为我安装的一切都是正确的。

$ cordova requirements

Answer 1

Unsupported major.minor version 52.0

表示Java 8个字节码，这意味着gradle是运行所在的JVM是旧版本。您应该检查 java -version 以查看默认的 JVM 是什么，并可能更新 JAVA_HOME 环境变量以便使用 Java 8 JDK。
