CodeRay throws error in Rails console

Question

I'm running Rails 4 and whenever I try running anything in the rails console, I get the following error:

2.0.0 (main):0 > User.first
CodeRay::Scanners::Scanner::ScanError:

***ERROR in scanner.rb:333:in `raise_inspect': no implicit conversion of Array into String (after  tokens)

tokens:


current line: 1  column: 5  pos: 4
matched: nil  state: "Error in CodeRay::Scanners::Ruby#scan_tokens, initial state was: :initial"
bol?: false,  eos?: false


surrounding code:

nil ~~ ".first"

ERROR

from /Users/silasjmatson/.gem/ruby/2.0.0/gems/coderay-1.1.0/lib/coderay/encoders/terminal.rb:145:in `text_token'

2.0.0 (main):0 >

My Gemfile.lock is like so:

Any Help?

Answer 1

If you're like me and want to keep using pry, changing your Gemfile to have the following fixes this issue.

gem "pry", "0.9.12.2"

Answer 2

Try removing pry from your Gemfile.

Answer 3

I removed any CodeRay related code from my .pryrc and it works again.
