Rails 4 console with spring locked

Question

I'm using Ruby 2.1.1 and Rails 4.1.0.rc1. When excute rails c, it's locked.

Using Ctrl-C to stop, I got error logs belore:

~/.rvm/gems/ruby-2.1.1/gems/spring-1.1.2/lib/spring/client/run.rb:47:in `gets': Interrupt

    from bin/rails:3:in `<main>'

After spring removed, rails c resumed.

Answer 1

Solved by updating Rails 4.1.0.rc1 to 4.1.0.rc2

Answer 2

I had this issue today on Ruby 2.1.1 and Rails 4.0.3, and I managed to fix it by stopping spring before trying again:

$ spring stop
Spring stopped.
$ bundle exec rails c
Loading development environment (Rails 4.0.3)
[1] pry(main)>
