Eclipse 4.2 Juno 找不到 JRE

Question

我下载了 Eclipse Juno 并尝试首次运行它。系统是Win 7 Home Premium，我也下载了JDK。我收到以下错误:

A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: C:\Program Files\eclipse\jre\bin\javaw.exe javaw.exe in your current PATH

它需要的javaw.exe 文件在...C:\Program Files\Java\jre7\bin\javaw.exe

如何解决这个问题？提前致谢

" A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: C:\Program Files\eclipse\jre\bin\javaw.exe javaw.exe in your current PATH "

您需要安装Java JDK:http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

然后编辑你的路径位置:

右键单击 computer -> properties -> advanced system settings -> advanced -> environment variables :

添加C:\Program Files\Java\<JDK version>\bin到您的 PATH 变量。

同时添加 JAVA_HOME作为系统变量。我有我的 JAVA_HOME设置为 C:\Program Files\Java\jdk1.7.0_03 .

完成后，开始cmd , 输入 java , 然后按回车。如果您收到找不到它的错误，则说明 java 未正确安装。
