pasta / omniauth-viadeo Goto Github PK

Everything is working just fine in development. But when I try to deploy my app on staging or production I get this error while lauching a rake task or the server itself

Could not find matching strategy for :viadeo. You may need to install an additional gem (such as omniauth-viadeo).

I'm already using Facebook, Twitter, LinkedIn, Google and OpenId strategies in the same way and there are all working well.
I have already filled my Viadeo credentials and have tried calling provider with :viadeo and "viadeo" but still get the error message.
So I think there is undoubtedly something wrong with this one.

Also I'm apparently not the only one, see this stackoverflow post
