安装好Eclipse后，启动报错：

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

    此报错信息翻译过来就是：为了运行Eclipse，必须安装jre或者jdk。并且在C:\Program Files\eclipse\jre\bin\javaw.exe下没有发现java虚拟机。环境变量PATH下也没有发现虚拟机。

    Eclipse启动时出现如上信息的原因是：本机根本就没有安装jdk
