I'm trying to apply fragment caching to one of my jbuilder views:

I am trying to upgrade a rails 4.2 application to 5.2.3.
My system is MacOS 10.14.6 Mojave. Bundler version 2.0.2

Here is the error after I did bundle update:

I'm doing this upgrade for the first time and I'm facing problem on very first step :-(

Basically I want to upgrade rails version of my project so I changed my Gemfile for the rails 5.2 and tried to run:

Use the activeadmin into the gem file. bundle install, rails g active_admin:install User, then rails s, the server will crash and give some warning.

Error Information:

rails s

...

While upgrading our app from Rails 3.2.22 to Rails 4.2.11, several CarrierWave methods that worked prior to the upgrade now return nil, such as .url and .file. We are hosting our assets on AWS S3 and our app is hosted on Heroku. Strangely, the images work as expected in our dev environment.

CarrierWave 1.3.1 (upgraded from 0.11.2)

Rails 4.2.11, upgraded from 3.2.22

Ruby 2.2.5

fog-aws 3.3.0

So far I have tried changing around the carrierwave config, and playing around with different methods in the rails console and comparing the results in development with production.

I'm clone plugin in /usr/share/redmine/lib/plugins from git clone https://github.com/iRessources/AgileDwarf . When i execute in directory /usr/share/redmine bundle install --without development test --no-deployment Output:
