Android Errno:：enoint:没有这样的文件或目录-ant

我试图通过以下命令在我的linux机器上生成ruboto应用程序：

$ ruboto gen app --package org.ruboto.example.quick_start

但我得到了这个错误：

rake aborted!
Errno::ENOENT: No such file or directory - ant
/opt/projects/quick_start/rakelib/ruboto.rake:14:in ``'
/opt/projects/quick_start/rakelib/ruboto.rake:14:in `<top (required)>'
(See full trace by running task with --trace)

rake中止！
Errno:：enoint:没有这样的文件或目录-ant
/opt/projects/quick_start/rakelib/ruboto.rake:14:in`'
/opt/projects/quick_start/rakelib/ruboto.rake:14:in`'
（通过使用--trace运行任务查看完整跟踪）
