我刚买了一台新笔记本电脑，所以我试图将一个项目转移到它上面，但无法启动并运行数据库。我之前在运行linux，但现在正在Mac上运行Yosemite。
我在Rails 3.0.3（它是一个升级项目），Ruby 1.9.3
当我运行bundle exec rake db:schema:load --trace
它说它在这一行打破了：
default_scope order("created_at ASC")
。
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
Could not find table 'comments'

如果我从评论模型中完全删除该行，则运行bundle exec rake db:schema:load时的错误只是：
rake aborted!
Stack level too deep
有什么想法吗？
第二次修改
当我运行bundle exec db:create时，它运行正常，并说数据库已经存在。
当我尝试创建表格时，它正在崩溃......
答案 0 :(得分：0)
如果在尝试升级到Rails 3时遇到其他任何人遇到此问题，我设法通过删除名为“bj”的gem来修复它。即使你没有这个特定的宝石，我也会建议你浏览每一颗宝石，确保它们仍然支持Rails 3 ......
