在ubuntu 13.10 amd64上安装grails

Question

我是新手使用grails并使用amd64的ubuntu 13.10。当我使用gvm成功安装grails 2.3.2然后在我的bash中输入 grails create-app test 时，会出现以下错误：

Loading Grails 2.3.2
Error Error executing script sun.reflect.GeneratedConstructorAccessor1 cannot access 
its superclass sun.reflect.ConstructorAccessorImpl 
(Use --stacktrace to see the full trace)

当我输入 grails 时，会出现错误：

Loading Grails 2.3.2

我也使用gvm来安装groovy，但是当我键入groovy时，它也有错误。 怎么了？

请执行并允许对此整个Grails文件夹的权限

只需输入

即可使grails可执行文件具有正确的权限

`sudo chmod u+x /grailsdirectory/./grails`

`sudo chmod u+x grails-2.3.4 `


`chmod -R 777 /Your/folder/path/`

如果您只想让文件读写，请将权限分配给766。

Dude请重新安装grails如下：

sudo add-apt-repository ppa：groovy-dev / grails sudo apt-get update sudo apt-get install grails-ppa

在我的情况下添加grails 2.3.0 //

sudo apt-get install grails 2.3.0

然后不要忘记设置grails文件夹和可执行文件的权限并添加nessary environemnt varibles：

your JAVA_HOME directory setting
export JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun-1.5.0.xx

#your GRAILS_HOME directory setting
export GRAILS_HOME=~/grails-1.0-RC2

#your PATH setting to append the Grails bin directory
export PATH=$PATH:$GRAILS_HOME/bin

并且，groovy和grails zip包也可以下载并提取到你想要的文件夹，thens setpermission然后打开或Insatll STS配置grails和groovy thier和ENVIRONEMNTVARIABLES从命令行运行grails然后这很简单相信我！
