运行linner new webapp报错

[loveky]

信息如下

=> linner new webapp && cd webapp
/Users/gewang/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:55:in `require': /Users/gewang/.rvm/gems/ruby-1.9.3-p194/gems/linner-0.1.0/lib/linner/sort.rb:4: syntax error, unexpected tLABEL, expecting ')' (SyntaxError)

莫非def sort(before: [], after: []) 是想写成 def sort(before = [], after = [])

你 ruby 版本太低, 升级 ruby 2.0 先...

Based on Ruby 2.0 keyword arguments.

追随 Matz 的脚步, 升级吧.

@loveky ReadMe 里面加上了 Requirements.

用了好多 Ruby 2.0 特性, to_h 太好用了, 还有 keyword arguments. 还有 File 默认的 UTF-8 Encoding..

过段时间都装了 mavericks 就没人抱怨了
