Question

我正在尝试创建简单的cordova样本并按照以下步骤操作。当我添加平台时，它显示错误陈述＆＃34;不支持的major.minor版本52.0＆＃34; 。请帮忙。提前致谢。

步骤：

1.通过npm install -g cordova安装cordova 2.通过cordova创建一个app创建hello com.example.hello HelloWorld 3.试图通过cordova平台添加android平台来添加android平台

要解决此错误，请尝试安装android sdk 23,24和25 4.还检查了显示gradle安装的cordova要求。

我删除了平台android并试图再次添加它得到了同样的错误

错误：

Cordova版本：6.4.0

Answer 1

将jdk更新为1.8，确保environment variable名为JAVA_HOME的{{1}}指向jdk 1.8的安装位置。

Answer 2

我有同样的错误。请降级cordova版本：

npm uninstall -g cordova
npm install -g cordova@5.4.1

Cordova添加平台失败，异常不支持major.minor版本52.0
