我遵循以下指南为Ruby env安装linalg。
http://www.quora.com/Installation-Instructions/How-do-I-install-Ruby-linalg-library-on-Mac
它有效，但是当我尝试在'irb'中要求lib时，它会引发错误。
环境：Ruby：2.0.0-p0 lapack：3.5.0（我也试过3.4.0）
我已经花了3个小时，但没有弄清楚问题。 当我尝试在命令行中要求lib时，这是错误。
似乎某处使用18作为参数，超过最大值为-2..15。
2.0.0-p0 :002 > require 'linalg'
ArgumentError: arity out of range: 18 for -2..15
