java更改mac os中的java_HOME变量

Question

我通过使用下面的命令将JAVA_设置为HOME进行了更改

rajendras-mbp:demo username$ /usr/libexec/java_home 
/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home
rajendras-mbp:demo username$ export JAVA_HOME="`/usr/libexec/java_home -v '1.8*'`"
rajendras-mbp:demo username$ java -version
java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

当我检查java版本时，它设置了JDK 1.8

但是在我点击ionic cordova run 安卓之后，它抛出了下面的错误

ANDROID_HOME=/Users/username/Library/Android/sdk
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home
(node:2191) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): CordovaError: Requirements check failed for JDK 1.8 or greater

改变什么？如何将1.8 JDK设置为ionic

Answer 1

将以下内容添加到~/。简介和~/。bashrc（/etc/bashrc，然后是~/.bashrc）对于您的用户：

export IDEA_SDK=$(/usr/libexec/java_home -v 1.8)
