uninitialized constant Devise (NameError)

I have a problem when deploying my app in production... My Gemfile contains gem 'devise' and everything work fine in development...

Here is my unicorn_stderr.log file where [XXXXXX] is my rails app folder.

I don't understand the problem...I googled this but i found nothing helping me, I hope somebody can help me !

回答1:

I fixed it... My script/rails and config/unicorn_init.sh wasn't executable so a simple chmod u+x on these files solved my problem. It wasn't a problem with devise !

回答2:

Have the same issue today on production server after I deploy new version with Devise. I read a lot of topics, checked all configuration files, everything was OK but unicorn wrote the next in log file:

ERROR -- : uninitialized constant Devise (NameError)

My solution was: to STOP and to START unicorn daemon. RESTART doesn't help. As a flag of success - you need to check /tmp/pids/ folder. When you stop the process, this folder becomes empty.
