我使用的是rake 10.0.4并且我已升级到10.1.0，但现在当我部署到我的登台服务器时它会抛出我：

(See full trace by running task with --trace)
我的Rakefile没有什么特别之处：
#!/usr/bin/env rake
# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.
require File.expand_path('../config/application', __FILE__)
MyApp::Application.load_tasks
如果我再次降级到10.0.4，它可以正常工作。任何线索？

种子库宝石已知问题。最新版本的种子库（0.2.1）仍然存在问题，因此seedback issues中的建议是使用Gemfile中github的版本：
gem 'seedbank', github: 'james2m/seedbank'
