Bundler::GemNotFound: Could not find mimemagic-0.3.5 in any of the sources on Rails project with Docker

Question

I'm aware of the recent mimemagic issues, which I managed to resolve on one of my Rails projects by bundle updating to 0.3.7 - but for some reason, I can't resolve it on the project below.

I have a Rails 6 project which I'm setting up for the first time on a new laptop. My laptop doesn't have the correct Ruby setup, so I've added a Dockerfile to my project like so:-

Dockerfile

FROM ruby:2.7
RUN apt-get update -qq && apt-get install -y nodejs postgresql-client
WORKDIR /radius
COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock
RUN bundle update mimemagic
RUN bundle install
COPY . /myapp


COPY entrypoint.sh /usr/bin/
RUN chmod +x /usr/bin/entrypoint.sh
ENTRYPOINT ["entrypoint.sh"]
EXPOSE 3000


CMD ["rails", "server", "-b", "0.0.0.0"]

Gemfile

gem 'sidekiq', '~> 5.2', '>= 5.2.5'
gem 'sitemap_generator', '~> 6.0', '>= 6.0.1'
gem 'underscore-rails'
gem 'whenever', require: false

I then try:-

docker-compose build
docker-compose up

Along with every combination of the following:-

• Using bundle update mimemagic in my dockerfile
• Adding the gem specifically to my Gemfile with gem 'mimemagic', '~> 0.3.7'
• Manually changing my Gemfile.lock mimemagic version from 0.3.5 to 0.3.7
• Adding RUN apt-get install shared-mime-info to my Dockefile

and I simply get one of the below:-

Could not find mimemagic-0.3.x in any of the sources

web_1  | Bundler::GemNotFound: You have requested:
web_1  |   mimemagic ~> 0.3.7
web_1  | 
web_1  | The bundle currently has mimemagic locked at 0.3.5.
web_1  | Try running `bundle update mimemagic`

I've also tried bumping rails to 6.0.3.6 and running the docker build again, which gives me activesupport issues:-

web_1  | Bundler::VersionConflict: Bundler could not find compatible versions for gem "activesupport":
web_1  |   In snapshot (Gemfile.lock):
web_1  |     activesupport (= 6.0.3.5)
web_1  | 
web_1  |   In Gemfile:
web_1  |     rails (~> 6.0.3.6) was resolved to 6.0.3.6, which depends on
web_1  |       activesupport (= 6.0.3.6)
web_1  | 
web_1  |     dotenv-rails was resolved to 2.7.6, which depends on
web_1  |       railties (>= 3.2) was resolved to 6.0.3.5, which depends on
web_1  |         activesupport (= 6.0.3.5)
web_1  | 
web_1  | Running `bundle update` will rebuild your snapshot from scratch, using only
web_1  | the gems in your Gemfile, which may resolve the conflict.

What exactly do I need to do to get this gem to install?

Answer 1

bundle update --conservative mimemagic 

also try with newer version rather than locking it. it worked for us with 0.3.9, but now there is 0.3.10(have not tried it),

Answer 2

Solved it using:

bundle update mimemagic

I was getting the error Your bundle is locked to mimemagic (0.3.5) from rubygems on bundle install.

This updated mimemagic version to 0.3.10 and added nokigiri and rake dependencies in Gemfile.lock for me.

Answer 3

You can modify your Gemfile as below:

gem 'mimemagic', github: 'mimemagicrb/mimemagic', ref: '01f92d86d15d85cfd0f20dabd025dcbd36a8a60f'

Answer 4

For my case this was the solution from macOS: 'You will require a copy of the Freedesktop.org shared-mime-info database to be available. If you're on Linux, it's probably available via your package manager, and will probably be in the location it's being looked for when the gem is installed.

macOS users can install the database via Homebrew with brew install shared-mime-info.' https://github.com/mimemagicrb/mimemagic
