Getting error when updating puma gem using bundler-CodePudding

I am trying to update puma gem using bundle in my application through this command

bundle update puma

But it is showing this error

Your bundle is locked to elasticsearch-model (7.1.1) from https://github.com/elastic/elasticsearch-rails.git (at 6.x@606f348), but that version can no longer be found in that source. That means the author of elasticsearch-model (7.1.1) has removed it.
You'll need to update your bundle to a version other than elasticsearch-model (7.1.1) that hasn't been removed in order to install.

I am not sure what it means. When I search inside my gemfile for " elasticsearch " I am getting only one match which is

gem "elasticsearch-persistence", git: "https://github.com/elastic/elasticsearch-rails.git", branch: "6.x"

Similarly when I search for " elasticsearch " inside Gemfile.lock here are the matches

  elasticsearch-persistence!

Any idea how can I resolve this error? Thanks

CodePudding user response：

The elasticsearch-model gem is a dependency of the elasticsearch-persistence gem. Because your Gemfile only has an entry for the elasticsearch-persistence bundler will try to load the latest version of the elasticsearch-model gem it can find.

Furthermore, you do not load the elasticsearch-persistence from Rubygems but directly from their GitHub repository. But bundler will load the elasticsearch-model dependency from Rubygems.

I agree that the error message is very confusing. And I guess that the latest version of elasticsearch-model is simply not compatible with the older version of elasticsearch-persistence from GitHub.

I suggest just changing the elasticsearch-persistence line from your Gemfile to the following to ensure that both gems are loaded in the same version from the same source (like suggested in the README):

gem 'elasticsearch-model', github: 'elastic/elasticsearch-rails', branch: '6.x'
gem 'elasticsearch-persistence', github: 'elastic/elasticsearch-rails', branch: '6.x'

And then try running bundle install again.
