用于nil:NilClass的paypal_adaptive gem未定义方法to_sym已投入生产，但尚未投入开发

Question

我正在尝试用paypal_adaptive gem开发一个小应用，但是每次我尝试这样做的时候：

ipn = PaypalAdaptive::IpnNotification.new

它在开发时有效，但在mysql的生产中失败，并出现以下错误：

NoMethodError:未定义的方法从(Irb)初始化‘from /usr/local/rvm/gems/ruby-1.9.3-p327/gems/paypal_adaptive-0.3.2/lib/paypal_adaptive/config.rb:69:in new' from /usr/local/rvm/gems/ruby-1.9.3-p327/gems/paypal_adaptive-0.3.2/lib/paypal_adaptive/config.rb:69:in’from NoMethodErrorinitialize' from (irb):1:into_sym' for nil:NilClass from /usr/local/rvm/gems/ruby-1.9.3-p327/gems/paypal_adaptive-0.3.2/lib/paypal_adaptive/config.rb:28:in‘from (irb):1from /usr/local/rvm/gems/ruby-1.9.3-p327/gems/railties-3.2.8/lib/rails/commands/console.rb:47:in rails开始‘from /usr/local/rvm/gems/ruby-1.9.3-p327/gems/railties-3.2.8/lib/rails/commands.rb:41:in start' from /usr/local/rvm/gems/ruby-1.9.3-p327/gems/railties-3.2.8/lib/rails/commands/console.rb:8:in<top (required)>' from script/rails:6:in’from script/rails:6:in‘’

Answer 1

不要紧。我发现我在配置文件中遗漏了一行。这是一个我在测试中没有发现的愚蠢的错误。
