Incompatible rubygems 2.6.2 and bundler < 1.12.0.rc on ruby:2.3.0-*

[taonic]

See the closed issue on bundler: rubygems/bundler#4381. They had the compatibility issue fixed on 1.12.0.rc (through rubygems/bundler#4341) but the problem remain unsolved on 2.3.0-slim Dockerfile with the incompatible rubygems-2.6.2 and bundler-1.11.2.

How do we deal with this situation? Rollback rubygems to 2.6.1 or install bundler 1.12.0.rc?

I'm also running into the same issue. Reverting to the 2.2 image for now.

[taonic]

I don't think everyone can revert back to 2.2 easily if they have started using some of the 2.3 features.

[JeanMertz]

Very true. And in fact, the 2.2 images where also updated with the latest Rubygems version, so they didn't work for me either.

I'm surprised that more people haven't ran into this issue yet.

The solution for me was to add the following to statements to the Dockerfile ineriting from _/ruby:

RUN gem update --system 2.6.1
RUN gem install bundler --version $BUNDLER_VERSION

Got the same problem :/

I hit this problem when using guard with my binstub (e.g. /app/bin/guard), not global binstub (/usr/local/bundle/bin/guard). I guess guard is calling bundle exec, so it hit the same problem - bundle exec inside bundle exec.

It can be fixed by installing the same version of bundler inside docker, so I don't think this is a issue of rubygems/bundler.

See the following script with output. I don't know how it fixes the problem.

docker run -it ruby:2.3.1 /bin/bash

Looks like bundler 1.12.0 landed in 339c325
Can this be closed?

[javiercr]

The new image hasn't been pushed to Docker Hub yet so I'm still getting the same error.

[javiercr]

With the latest version of the ruby:2.2 image I'm getting the same problem:

Me too on ruby:2.1.

[atipugin]

Same here, ruby:2.3.1.
