我最近在 nettuts 上开始了“Intro to Rails”截屏视频。所以我显然对 Rails 不是很熟悉,对 Ruby 也只知道一点。代码中的其他所有内容都将正常运行,但是当我运行 guard-rspec 时,它会显示:
/Users/hanssingh/.rvm/rubies/ruby-2.0.0-p195/lib/ruby/2.0.0/minitest/unit.rb:1013:in `block in process_args': invalid option: -f (OptionParser::InvalidOption)
from /Users/hanssingh/.rvm/rubies/ruby-2.0.0-p195/lib/ruby/2.0.0/minitest/unit.rb:992:in `new'

from /Users/hanssingh/.rvm/rubies/ruby-2.0.0-p195/lib/ruby/2.0.0/test/unit.rb:365:in `block in autorun'
我不太确定这个错误是什么意思,我该如何摆脱它?
