Translation bundling error in Ruby on Rails

Question

I've recently updated my Ruby on Rails project and then when I try to run the rake i18n:js:export command, I'm getting the following error

uninitialized constant I18n::INTERPOLATION_PATTERN

This happens in both windows 8.1 and centos6 machines.

My ruby version is: 1.8.7 in windows and 1.9.3 in CentOS6 Rails version: 3.0.9

I'm clueless in this spot and tried to find a solution, and couldn't find a correct one.

I'm using i18n-js version 2.1.2

I tried updating it to version 3.0.0.rc5 but still no luck.

Anyone came across any issues similar to this? I'm eagerly expecting a solution to fix this issue.

Is there more stack trace? Does it reference a line in your file, and if so what is the code on that line? — Beartech
@Beartech: I've updated the question and now added the stack trace from the centos. Could you please check it — Mujahid
When you say you updated, what did you change? Do you mean you updated the Rails version? You could try running the rake command with --trace to get more info. It's complaining that it can't find the constant I18n::INTERPOLATION_PATTERN defined anywhere. Is there a require... missing somewhere? — Beartech
@Beartech: I added the result after I run with trace. And this is my i18n-js file auto_export: no translations: - file: "public/javascripts/translations.js" only: "*" asset_pipeline: yes — Mujahid

I know this is an outdated issue, but you may want to look at this recent SO question. It details how I ran into a similar issue and how it was resolved:

upgrading to ruby 2.3.0 NameError: uninitialized constant I18n::Config::Backend

Look through your rake files and see if you have any references to the Translation helper.

Removing include ActionView::Helpers::TranslationHelper and replacing (t "some_text") with (I18n.t "some_text") completely resolved the issue.
