本文介绍了在Mac上为JAVA_HOME的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

echo $ JAVA_HOME给我:

echo $JAVA_HOME gives me:

但是尝试使用此设置将项目导入Intellij无效.我的JAVA HOME是否必须位于

But trying to import a project to Intellij with this setting doesn't work. Does my JAVA HOME have to be in

如果是这样，我该如何使用目前的产品呢?

if so, how do I make it so with what I currently have?

"/usr/libexec/java_home -V"的输出

output of "/usr/libexec/java_home -V"

/Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home

推荐答案

3件事适用于JAVA_HOME应该在其中的ENV变量.ENV是一个有范围的字典"，它在操作系统上启动的每个进程都被实例化/加载.

3 things apply to your ENV variables in which JAVA_HOME should be. ENV is a scoped 'dictionary' which is instantiated/loaded with every process being started on an OS.

通常通过SYSTEM配置和USER配置加载./etc中的文件被认为是SYSTEM-对于OSX，适用以下规则；最后加载的文件将覆盖以前的值:

It is generally loaded through SYSTEM config and USER config. The files residing in /etc are considered SYSTEM - and for OSX the following applies; last loaded file will overwrite previous values:

首先是/etc/profile，然后存在以下任意一个，按顺序尝试它们:〜/.bash_profile，〜/.bash_login或〜/.profile

First /etc/profile, then whichever of the following exists, trying them in order: ~/.bash_profile, ~/.bash_login, or ~/.profile

/etc/bashrc，然后是〜/.bashrc

/etc/bashrc, then ~/.bashrc

如果实际加载IntelliJ的脚本具有用于设置ENV变量的机制，则当然是带有最后一个单词"的机制.

THEN if the script, that actually loads IntelliJ has a mechanism for setting ENV variables, this will of course be one with the last 'word'.

对于IntelliJ，我认为为此目的使用了一个特定的变量，即IDEA_SDK.因此，将以下内容添加到USER的〜/.profile和〜/.bashrc中:

For IntelliJ i believe a specific variable is used for this purpose, namely IDEA_SDK. So add the following to both ~/.profile and ~/.bashrc for your USER:

export IDEA_SDK=$(/usr/libexec/java_home -v 1.8.0_73)

希望这行得通(确保命令正确无误-mby甚至不考虑版本参数)

Hope this works (make sure the command is just right - mby even just leave out the version arguments)
