uninitialized constant Encoding::US_ASCII

[calebperkins]

I started getting this upon upgrading from Rails 3.0.9 from Rails 3.0.7. However, even after I downgraded, I still this get this message. I also tried using MySQL2 version 0.2.7, but that didn't work either. What could be wrong?

What version of ruby are you using? Also, do you happen to have a class named Encoding in your application?

[calebperkins]

No, I do not have an Encoding class. I am using

ruby 1.8.7 (2008-08-11 patchlevel 72) [x86_64-linux]

, but I also tried with the latest Ruby Enterprise Edition and had the same problem.

[brianmario]

The offending line is here: https://github.com/brianmario/mysql2/blob/master/lib/mysql2/client.rb#L54

But you should only be getting there if there is a constant named Encoding defined: https://github.com/brianmario/mysql2/blob/master/lib/mysql2/client.rb#L51

Are you sure there isn't one in your app?

[calebperkins]

Got it! I had upgraded spectator-validates_email gem from version 0.0.4 to version 0.0.6. After downgrading the migration was able to run. It's a problem with how that gem uses the Encoding class. Thank you for helping me.

[brianmario]

no problem, let me know if you run into anything else :)
