Ruby Regex How to specify not to match

How do you say not to match in Ruby Regex

ex. you do not want to return true if it sees 'error'

/\b(error)\开发者_如何学Gob/i

I know this returns true when it sees error, how do you say 'not' in this case? thanks!

Use the proper Ruby operator:

/\b(error)\b/i !~ someText

I would do something like the following excuse the /error/ pattern not sure exactly what you want to match here

return true unless b =~ /error/

or

return true if b !~ /error/
