为什么我的 mac 不显示 java 版本？
[英]Why my mac is not displaying java version?
问题描述
Our help desk already installed Java 1.8_151 on our macbook pro Mohave.
我们的帮助台已经在我们的 macbook pro Mohave 上安装了 Java 1.8_151。 When I type 'which java' I get the reply as /usr/bin/java当我输入“which java”时，我得到的回复是/usr/bin/java
So, I added these two lines in my.bash_profile file in my home folder /Users/pnutalap所以，我在我的主文件夹 /Users/pnutalap 的 my.bash_profile 文件中添加了这两行
export JAVA_HOME=/usr/bin/java
export PATH=$JAVA_HOME/bin:$PATH
When I checked immediately 'java -version' I got back the java version correctly.当我立即检查“java -version”时，我正确地取回了 java 版本。 But today, I am getting totally different resonse like...但是今天，我得到了完全不同的共鸣，比如......
N201960-MAC:~ pnutalap$ java -v Unable to locate an executable at "/usr/bin/java/bin/java" (-1)
Why there is additional /java at the end?为什么最后有额外的 /java ？ What has gone wrong?出了什么问题？ And how to correct it to show java version properly?以及如何纠正它以正确显示 java 版本？

When I tried to move to /usr/bin/java, I got the reply当我试图移动到 /usr/bin/java 时，我得到了回复
N201960-MAC:~ pnutalap$ cd /usr/bin/java -bash: cd: /usr/bin/java: Not a directory N201960-MAC:~ pnutalap$ cd /usr/bin/java -bash: cd: /usr/bin/java:不是目录
Looks like within /usr/bin/ folder, the 'java' is not a directory, but a symbolic link.看起来在 /usr/bin/ 文件夹中，“java”不是目录，而是符号链接。 Now it makes sense why it is trying to say Unable to locate an executable at "/usr/bin/java/bin/java" simply going by the PATH variable.现在，为什么它试图简单地通过 PATH 变量说Unable to locate an executable at "/usr/bin/java/bin/java"是有道理的。
