unable to run innodb_space

[shenroong]

My system is 14.04 Ubuntu and the newest version of ruby.

I tried to install inndo_ruby both by sudo gem install innodb_ruby and from repo.
However, when I run innodb_space, it shows

vagrant@system-lock:/usr/local/mysql/data/test1$ innodb_space
/usr/local/bin/innodb_space:19:in `load': /var/lib/gems/1.8/gems/innodb_ruby-0.9.13/bin/innodb_space:720: syntax error, unexpected ')' (SyntaxError)
