Rails Rake db：create不起作用

Question

I come from a computer science and programming background, and I am familiar with a *nix CLI.

I am new to ruby on rails, and I am doing an online bootcamp. One of my lessons has me creating a new rails application. It starts out with the following commands to create a new rails application and create the database:

$ rails new bloccit -T
$ cd bloccit
$ rake db:create

When I run the rake command, the process just hangs. I let it run for 30 minutes, and it just sat there. When I do a hard interrupt, I get the following stack trace:

^C/Users/mikekeathley/.rvm/gems/ruby-2.2.1/gems/spring-1.3.4/lib/spring/client/run.rb:99:in `gets': Interrupt

I understand the stack trace: on line 99 in the run.rb file, the method gets is getting stuck. I just don't know anything about spring.

I am running Ruby 2.2.1p85, Rails 4.2.1, and sqlite3 1.3.10.

Answer 1

Stop spring by using command

bin/spring stop

and then run rake command again. It would fix this issue.
