当我在终端（Mac，运行最新版本的Yosemite）中输入$ rails服务器时，会弹出以下消息。我很丢失，其他主题建议改变我的项目的配置文件夹中的文本，但我尝试过的东西没有用，我猜是因为那些是稍微过时的主题。
我正在学习试图使这个MailChimp应用程序正常运行的Learn Ruby on Rails书籍，完成了第13章，没有任何大问题。任何帮助表示赞赏。

也许你的ENV变量没有正确设置，或者你在其中一个变量中有一个不寻常的字符。请注意 config / secrets.yml 文件中没有制表符或任何异常字符。
我建议你用硬编码字符串替换 config / secrets.yml 中的所有ENV值。不要使用文件中的私有凭据将文件检入git。只需测试它，看看你是否可以解决问题。
