我收到"在扫描下一个令牌时找不到任何令牌的字符"

Question

我已经在我的笔记本电脑上运行Ruby on Rails大约一个月了,但是当我想在这个实例中运行服务器时(几小时前工作正常)我现在收到这条消息.我怎样才能让服务器再次运行？

Answer 1

YAML不接受\t缩进的TAB字符().寻找你的那些config/application.yml并用2个空格替换.

(或者可能存在其他语法错误,如Ryan所建议的那样.但我打赌这个错误)

Answer 2

此错误源自Figaro gem,它会向我表明您可能有语法错误config/application.yml.仔细检查此文件是否有任何不正确的YAML语法.

Answer 3

可能不是您的特定示例，但是Stack Overflow的标题导致我出现在此职位上，因此对于那些使用此错误的人，原因可能是：

en.yml或翻译yml或任何yaml ...

字符串内插没有双引号

points:
  other: %{points} points

更正：

points:
  other: "%{points} points"

Answer 4

我和你的问题一样.我确定它的TAB字符(\ t)问题.请更换2个空格.
