我知道这不是代码的问题，因为它现在正在我们的服务器上运行。可能导致此问题的任何想法？
答案 0 :(得分：0)
'vouchers'代替'"vouchers"'
答案 1 :(得分：0)
此错误
rake aborted!
You have already activated rake 0.9.6, but your Gemfile requires...
现在并不重要。始终使用bundle
exec添加命令，这样你就会很好。
您的服务器应该在producion Rails环境中工作吗？如果 所以，你应该运行
RAILS_ENV=production bundle exec rake db:setup
但是由于第二个错误，它无论如何都不会起作用。
...PG::Error: ERROR: relation "vouchers" does not exist...
我相信这个错误的原因在于：
app/models/bags_discount.rb:7
BagsDiscount模型可能有一些scope，它使用
vouchers表。当您运行db:setup时，所有与应用程序相关
类已初始化，但表尚不存在。

UPD：如果你想快速＆amp;脏解决方案：只需注释掉问题行并在之后取消注释。这种耙子任务不应该太危险。
