Grails 安装

Question

I am trying to install grails in my windows 7, I have installed JDK 1.7.0 and downloaded grails from its site and extracted in path " C:\\grails ", i have jdk in " C:\\Program Files\\Java\\jdk1.7.0 ". I have set environment variable JAVA_HOME = "C:\\Program Files\\Java\\jdk1.7.0\\bin" and GRAILS_HOME = "C:\\grails" and added "%GRAILS_HOME%\\bin" and JAVA_HOME to path from advanced settings. But when i try to run "grails -v" or "grails help" i get the error "The system cannot find the path specified." . I even changed my directory to "C:\\grails" and ran "grails -v" but it is still giving me the same error.

I dont know what is wrong with it, please help me installing this thing. Thanks

Answer 1

JAVA_HOME = "C:\\Program Files\\Java\\jdk1.7.0\\bin"不能包含 'bin'

Answer 2

You'll want to verify that Java is working correctly first by entering "java -version" at the command line.

When you say you extracted the zip into " C:\\grails " does that directory now just have a single sub directory (ie " grails-2.5.0 " or whatever version you downloaded), or does it contain a bunch of sub directories (bin, conf, dist, doc. etc)?

If the answer is the former, your GRAILS_HOME should point to " C:\\grails\\grails-2.5.0 " instead of just C:\\grails\\
