无法在"/ usr/bin/java/bin/java"(-1)找到可执行文件

Question

我的mac osx 10.7.3中有一个可疑的Java问题.以前我安装它,它工作正常.在经过一段时间的.bash_profile和.profile文件的一些更改之后,我遇到了类似的错误

Unable to locate an executable at "/usr/bin/java/bin/java"

每当我尝试在我的终端中运行"javac"或"java"时.

echo $PATH 给出如下输出:

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/sabya/Documents/Play_Framework/play-2.0:/usr/X11/bin:/usr/local/git/bin:/usr/local/mysql/bin

我的.bash_profile看起来像:

alias start_mysql="/Library/StartupItems/MySQLCOM/MySQLCOM start"
alias stop_mysql="/Library/StartupItems/MySQLCOM/MySQLCOM stop"
export JAVA_HOME=/usr/bin/java

输出 which java

/usr/bin/java

它长时间困扰我,卸载和安装java并没有帮助我的运气.

我是Mac的新手,需要帮助解决这个问题.

在发布此问题之前用Google搜索并查看了SOF,但没有找到任何与我的问题相关的内容.

谢谢

Answer 1

最肯定的export JAVA_HOME=/usr/bin/java是,罪魁祸首.此env var应指向JDK或JRE安装目录.谷歌搜索显示,MacOS X的最佳选择似乎是export JAVA_HOME=/Library/Java/Home.

Answer 2

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home

因为:

 $ find /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home -name java*
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/java
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javac
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javadoc
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javafxpackager
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javah
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javap
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javapackager
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/javafx-src.zip
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre/bin/java

Answer 3

JAVA_HOME是不是Java可执行文件的名称.但是在目录中,安装了java.可执行文件应该是$JAVA_HOME/bin/java.

该which命令对你没有帮助.它不会给你java home,但很可能这只是一个安装在一个非常不同的目录中的java的包装器或符号链接.
