我来自计算机科学和编程背景，我熟悉* nix CLI。
我是ruby on rails的新手，我正在进行在线训练营。我的一课是让我创建一个新的rails应用程序。它首先使用以下命令创建新的rails应用程序并创建数据库：
$ rails new bloccit -T
$ cd bloccit
$ rake db:create
当我运行rake命令时，该过程就会挂起。我让它跑了30分钟，它只是坐在那里。当我进行硬中断时，我得到以下堆栈跟踪：
^C/Users/mikekeathley/.rvm/gems/ruby-2.2.1/gems/spring-1.3.4/lib/spring/client/run.rb:99:in `gets': Interrupt

我理解堆栈跟踪：在run.rb文件的第99行，方法得到了卡住。我对春天一无所知。
我正在运行Ruby 2.2.1p85，Rails 4.2.1和sqlite3 1.3.10。
答案 0 :(得分：2)
使用命令
停止弹簧bin/spring stop
然后再次运行rake命令。它会解决这个问题。
