刚刚通过 RVM Ruby 2.0.0 和 Rails 4.0.0 安装。开始了一个新项目,当尝试添加 gem 'factory-girl-rails' 并运行 bundle install 时,我收到了这个错误:
Fetching gem metadata from https://rubygems.org/.........
Fetching gem metadata from https://rubygems.org/..
Resolving dependencies...
Could not find gem 'factory-girl-rails (~> 4.2.1) ruby' in the gems available on this machine.
任何想法为什么会发生这种情况?
