Rails rake db：create不起作用

Question

我來自計算機科學和編程背景，我熟悉* nix CLI。

我是紅寶石新手，我正在做一個在線訓練營。我的一個教訓是我創建了一個新的rails應用程序。它一開始用下面的命令來創建一個新的Rails應用程序，創建數據庫：當我運行rake命令

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

，過程只是掛起。我讓它跑了30分鐘，它就坐在那裏。當我做一個硬中斷，我得到以下堆棧跟蹤：

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

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

我明白堆棧跟蹤：對在run.rb文件99行，該方法被被卡住。我對春天一無所知。

我運行Ruby 2.2.1p85，Rails 4.2.1和sqlite3 1.3.10。通過使用命令

bin/spring stop 

，然後再次運行rake命令
