我已经尝试从我的位置控制器中删除require'Time'行，但这并没有改变任何东西。

I have tried removing the require 'Time' line from my locations controller but this didn't change anything.

谢谢！

Thank you!

推荐答案

code> require'time' not Time 。这是ruby标准库文件的名称（即使模块本身是 Time ）。

I think you mean require 'time' not Time. That's the name of the ruby standard library file (even though the module itself is Time).
