离子构建失败:JAVA_HOME无效 [英] Ionic Build Failed: JAVA_HOME is invalid

问题描述

我想从离子性开始我的第一个构建.但是构建很快就会失败，并出现以下错误:

I wanted to start my first build with ionic. But the Build fails very soon with the following error:

Running command: E:\Apps\ASV\Node\node.exe E:\Apps\ASV\Code\MyASV\hooks\after_prepare\010_add_platform_class.js E:\Apps\ASV\Code\MyASV
add to body class: platform-android
Error: Failed to run "java -version", make sure that you have a JDK installed.
You can get it from: http://www.oracle.com/technetwork/java/javase/downloads.
Your JAVA_HOME is invalid: C:\Program Files\java\jdk1.8.0_77

过去一个小时，我尝试了几种方法来解决此问题.我卸载了所有与Java相关的东西，重新安装了它，将JAVA_HOME设置为jdk路径几次，将％JAVA_HOME％\ bin添加到路径变量，但没有任何方法可以解决.目前，我必须手动创建的JAVA_HOME如下所示:

I tried several things over the past hour to fix this. I deinstalled all Java related stuff, reinstalled it, set the JAVA_HOME several times to the jdk path, added %JAVA_HOME%\bin to the path-variable, but nothing fixed it. Currently my JAVA_HOME, which i had to create manually, looks like this at the moment:

C:\Program Files\Java\jdk1.8.0_77

请注意，此路径与错误消息中的路径不同. "Java"是用小写字母还是大写字母编写的，我不知道这是否有意义.同样，更改此JAVA_HOME变量，然后尝试重新生成也会产生相同的错误，更改后的变量似乎对一种离子用法没有影响.

Please note that this path is different to the one in the error message. The 'Java' is written in lowercase and in uppercase, I don't know if this is relevant. Also changing this JAVA_HOME variable and then trying a rebuild gives the same error, the changed variable seems to have no effect on the one ionic uses.

我该如何解决?到底是哪里出了问题?

How can I fix this? What exactly is going wrong?

推荐答案

好的，我已修复它.错误

Okay, i fixed it. The Error

Your JAVA_HOME is invalid: C:\Program Files\java\jdk1.7.0_79

很烦人.错误是PATH变量缺少

Is quite irritating. The error was that the PATH-variable missed an entry like

C:\Program Files\Java\jdk1.7.0_79\bin

不知何故

%JAVA_HOME%\bin

仍然会导致错误.
