更新后，对我的rails更新的任何请求，我收到此错误：

Your bundle is updated! Use `bundle show [gemname]` to see where a bundled gem is installed.
My Omniauth Initilaizer：
Rails.application.config.middleware.use OmniAuth::Builder do
provider :LDAP, "Ed-ITLDAP", :host => LDAP_HOST, :port => LDAP_PORT, :method => 'plain', :base => LDAP_BASE, :uid => 'sAMAccountName', :try_sasl => true, :sasl_mechanisms => "GSS-SPNEGO"
end
Omniauth 似乎不再需要/需要提供程序的名称，因此就我而言，我从提供程序行中删除了"EDITLDAP"选项，如下所示：
Rails.application.config.middleware.use OmniAuth::Builder do
provider :LDAP, :host => LDAP_HOST, :port => LDAP_PORT, :method => 'plain', :base => LDAP_BASE, :uid => 'sAMAccountName', :try_sasl => true, :sasl_mechanisms => "GSS-SPNEGO"
end
> @Arcath：检查您使用的任何中间件是否使用了正确的语法。我有同样的问题，问题是我的 config.ru 有
use Rails::Rack::Static
在 Rails 3 中现在是：
use Rack::Static
