每当我尝试部署我的应用程序时，cap production deploy:migrations都会收到一条错误消息：

我一直认为我的服务器存在一些配置问题，或者缺少一些依赖文件。但是在我的本地 Ubuntu 上，当我在终端中运行时：
bundle exec rake assets:precompile --trace
我得到：

# ==> Configuration for any authentication mechanism
# Configure which keys are used when authenticating a user. The default is
# just :email. You can configure it to use [:username, :subdomain], so for
# authenticating a user, both parameters are required. Remember that those
# parameters are used only when authenticating and not when retrieving from
# session. If you need permissions, you should implement that in a before filter.
# You can also supply a hash where the value is a boolean determining whether
# or not authentication should be aborted when the value is not present.
# config.authentication_keys = [ :email ]
# Configure parameters from the request object used for authentication. Each entry
# given should be a request method and it will automatically be passed to the
# find_for_authentication method and considered in your model lookup. For instance,
# if you set :request_keys to [:subdomain], :subdomain will be used on authentication.
# The same considerations mentioned for authentication_keys also apply to request_keys.

# config.token_authentication_key = :auth_token
# ==> Scopes configuration
