你的命令不正确。你应该改变：

bundle exec rake RAILS_ENV=staging RAILS_GROUPS=assets assets:precompile

... 到：

RAILS_ENV=staging RAILS_GROUPS=assets bundle exec rake assets:precompile

这个错误的原因是我从 Rails 2 应用程序复制了一些Errbit初始化程序的代码。该初始化程序中的代码使用了RAILS_ENV，这实际上导致了各种问题。我没有意识到应用程序甚至没有启动，因为我从直接添加 Errbit 初始化程序到尝试部署它。

因此，在吸取的一些经验教训中，使用Rails.env而不是RAILS_ENV在 Rails 3 中。
