我无法在我的Ubuntu机器上从GVM安装Grails；gvm安装grails不起作用

Question

我尝试使用GVM工具来安装Grails，在此之前，我将GVM从一个非常旧的版本更新到了最新版本。提示符出现后，我执行了gvm install grails，但由于连接问题而失败。我尝试通过输入相同的命令再次安装Grails。

Found a previously downloaded grails 3.0.1 archive.
Not downloading it again...
End-of-central-directory signature not found.  Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive.  In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one 
of /home/myhome/.gvm/archives/grails-3.0.1.zip or
/home/myhome/.gvm/archives/grails-3.0.1.zip.zip, 
and cannot find /home/myhome/.gvm/archives/grails-3.0.1.zip.ZIP, period.
Stop! The archive was corrupt and has been removed! Please try installing again.

Answer 1

尝试：

gvm list grails

这将为您提供所有已安装候选程序的列表。如果您安装了候选人，则应看到一个星号(*)符号和一个箭头，以显示正在使用哪个候选人。

如果他们真的出现了。尝试通过在安装时指定候选项来卸载它

gvm uninstall grails 3.0.1

然后再次尝试运行install命令。

它通常是有效的。
