capistrano-upload-config | Capistrano 3.x tasks | Continuous Deployment library

i have a 5.0.0.1 project that got problem deploying it. i use capistrano to deploy and it runs puma for me too. puma gets run and "Somthing went wrong" error shows up.
And now i have problem running project in my local development, weird! this errors shows up: ‍‍You have already activated activesupport 5.1.2, but your Gemfile requires activesupport 5.0.0.1. Prepending bundle exec to your command may solve this. (Gem::LoadError) And yes im only able to run project locally with bundle exec rails s.
Things i tried:
1. Clearing Gemfile.lock and bundle update and bundle install
2. Uninstalling 5.1.2 and it complaining you don't have 5.1.2
3. Because i'm using git, i went back to a commit that i was sure it worked. Nothing!
4. Try adding Activesupport 5.1.2 & 5.0.0.1 to gemfile. Nothing
5. Changing rails version to newer versions (Actually can't go to 5.1 because of deprecation warnings)
6. Checking Gemfile.lock and everywhere i see Activesupport, its 5.0.0.1 or something like >=4
