Rails strange error => IndexError: string not matched

Question

I\'ve got a very strange message error. I think it\'s not coming from Ruby but from the unix system.

So, I have the following test file:

require File         


        

Answer 1

This happens, for example, when you try to access a string variable as a Hash by mistake.

s = "a string"
s["position"] = "an other string"

IndexError: string not matched
    from (irb):5:in `[]='
    from (irb):5

As Simone points out the error is caused when you think you have a hash but really it a string. Its a genuine Ruby exception. I've had the exception due to a typo in my code. In your case I'm not sure of the cause but it could be something to do with a combination of Ruby / Rails versions.

You could try up/down grading Ruby or Rails to see if that fixes it.

For multiple Ruby versions I would highly recommended "RVM":http://rvm.beginrescueend.com/
