I already installed deps by run 'composer update'.

Poking back here, @Hoto Cocoa, did you successfully fix the issue? Or you got stuck somewhere? :)

No changes.

Thanks for reporting this @Hoto Cocoa, could you report this issue here: https://phabricator.wikimedia.org/project/view/1424/ by filing a phabricator task? Also, I think you should install dependencies (for the first time) by running `composer install` instead. Let me know if this helps.

What Alangi Derick says. To use Extension:Mailgun, you must run composer for the MailGun extension. phab:T206415 was created, and has accordingly been declined.
