I'm getting this too, for both scss and js

Hi there,

I'm running a project that uses:

• Ruby 2.3.0
• Rails 5.0.1
• Bundler 1.16.1
• select2-rails 4.0.3

I'm not having that issue.

Have you added *= require select2 in the app/assets/stylesheets/application.scss file?

Most of the time, when I've encountered File not found errors in Rails, they have been fixed by restarting the server. Let me know if that fixes the issue.

Regards.

Hey thanks.

Filed this issue long back. Have done so many changes post that, including version upgrades. Looks like one of the upgrades fixed the issue.

Closing this issue as I can see some commits regarding this issue and most people would have upgraded versions.
