我正在尝试为我的本地开发启动WEBRick而没有任何成功。以下是我收到的错误消息。有关它可能失败的原因的任何见解？

Answer 1

您错误地插入了字符串，插值以井号（#）开头，而非美元。

您需要将此字符串更改为：

 FACEBOOK_CONFIG = YAML.load_file("#{::Rails.root}/config/facebook.yml")[::Rails.env]

或者在没有插值的情况下这样做：

sth = YAML.load_file(Rails.root.join 'config', 'facebook.yml')

WEBRick没有启动，抛出了无效的参数错误
