已安装Java 7，但终端仍为Java 6 [英] Installed Java 7, but interminal still Java 6

问题描述

我已经在Mac(10.7.5)上安装了Java 7，但是在终端中仍然有Java 6.

java版本"1.6.0_37"；Java(TM)SE运行时环境(内部版本1.6.0_37-b06-434-11M3909)Java HotSpot(TM)64位服务器VM(内部版本20.12-b01-434，混合模式)

如果我在尝试安装Java应用程序时总是遇到该错误，则终端上的版本6不会有问题( LatexDraw ):

:CGContextGetCTM:无效的上下文0x0

:CGContextSetBaseCTM:无效的上下文0x0

:CGContextGetCTM:无效的上下文0x0

:CGContextSetBaseCTM:无效的上下文0x0

该问题与从 此链接推断的 java 6 的不稳定性有关>

我已阅读，但是在我的文件夹/System/Library/Frameworks/JavaVM.framework/Versions 中，版本1.7，仅1.6版以下的版本???那么，如何解决此问题?

解决方案

您可以通过以下方式解决:

• 以这种方式获取已安装的Java 7 JRE的路径:

  /usr/libexec/java_home -v 1.7

• 将上一个命令的输出设置为 JAVA_HOME variale(例如，在我的情况下):

  export JAVA_HOME =/库/Java/JavaVirtualMachines/jdk1.7.0_07.jdk/Contents/Home

I've installed Java 7 on my Mac (10.7.5), but in the terminal there is still java 6.

java version "1.6.0_37" Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

There will be no problem with the version 6 on terminal, if I always got that errors when I tried to install a java application (LatexDraw):

: CGContextGetCTM: invalid context 0x0

: CGContextSetBaseCTM: invalid context 0x0

: CGContextGetCTM: invalid context 0x0

: CGContextSetBaseCTM: invalid context 0x0

The problem is related to instability of java 6 inferred from this link

I've read this installed-java-7-on-mac-osx-but-terminal-is-still-using-version-6 and also try to change my Java version by using export JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home", but in my folder /System/Library/Frameworks/JavaVM.framework/Versions, there is no version 1.7, only versions under 1.6 ??? So, how can I fix this issue?

解决方案

You can solve in this way :

• Get the path of your installed Java 7 JRE in this way :

  /usr/libexec/java_home -v 1.7

• Set the output of the previous command as JAVA_HOME variale(for example in my case) :

  export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk/Contents/Home
