不知道如何在Ubuntu natty上构建rake db:migrate？

Question

我不确定如何使用Capistrano部署应用程序,但我想我至少尝试在部署服务器上加载我需要的所有文件,所以我在Github上做了一个git pull并使用bundle install安装了所有依赖项.我使用Rails 3.0.9在Ruby 1.9.2p180中运行RVM 1.6.32,当我运行rake db:migrate时,我得到了

rake aborted! Don't know how to build task 'db:migrate'

我没有其他SO用户提到的双分号问题,所以我真的很困惑.我安装了0.9.2和0.8.7,以及捆绑器1.0.17.我的rvm实例显示 rake (0.8.7 ruby)

出了什么问题？

Answer 1

检查文件中是否有require 'rails/all'礼物config/application.rb.看起来sunspot已经改变了你的配置.

您也可以尝试先更新您的捆绑包 gem update bundler

Answer 2

尝试运行bundle exec rake db:migrate.问题可能是你没有从bundle中加载gem,因此没有得到那些gem中定义的任务(比如Rails!).
