So I get a uninitialized constant Dalli (NameError) when I push my ruby on rails app to my staging on heroku, but it works fine in production. my production.rb and staging.rb files are the exact same except for a mailer host value. Could someone help? Thanks!

看看你的Gemfile：

group :production do
  gem 'dalli'
end

Bundler 不会在您的暂存环境中加载 Dalli。要么将其移出:production组，使其在所有环境中可用，要么也将其添加到:staging环境中。
