原因是在Rspec3中删除了RSpec :: Core :: CommandLine

The reason is that RSpec::Core::CommandLine was removed in Rspec3

将RSpec :: Core :: CommandLine(从未正式声明为公共)合并到RSpec :: Core :: Runner中. (迈伦·马斯顿)

Merge RSpec::Core::CommandLine (never formally declared public) into RSpec::Core::Runner. (Myron Marston)

但是spork取决于此代码.

But spork depends on this code.

spork的github上已经存在问题，可以在以下spork的fork中找到解决方案:

There is already an issue on spork's github and a solution can be found in a following spork's fork:

通常-替换

::RSpec::Core::CommandLine.new(argv).run(stderr, stdout)

使用

::RSpec::Core::Runner.run(argv,stderr, stdout)
