Running Rails 3.0.7 and ruby-1.9.2-p180.

Issue was discovered while updating a rails 2.3.11 app to rails 3.

Please let me know if you need any other information.

Thanks

Report it to ActiveSupport.
The bundled JSON module does not provide JSON.decode.

[tboilard (Tom Boilard)]

From the error message above it appears that the issue is related to ruby 1.9.2 and psych. The issue does not occur when running rails 3.0.7 and ruby 1.8.7.

Hi,

Tom, thank you for your report.

I think this issue was fixed in trunk by r30957.
And it was already back-ported to ruby_1_9_2 branch by r31769.
Please wait the new 1.9.2 patch level release.

Regards,
