gem install gazer -v 0.2.54 fails

[alec-flatiron]

Hi all, in a dockerfile we get gazer installed (v0.2.54) - today we started to get an error, which seems associated with a new release of the multipart-post package.

We run

RUN apt update
RUN apt -y install ruby
RUN gem install gazer -v 0.2.54

This errors with: Error installing gazer: The last version of multipart-post (~> 2) to support your Ruby & RubyGems was 2.2.0. Try installing it with gem install multipart-post -v 2.2.0 and then running the current command again. multipart-post requires Ruby version >= 2.6.0. The current ruby version is 2.5.0.

I see in the Gemfile.lock there is an entry for multipart-post (2.1.1) - I don't know rails, so evidently that is not the version being installed. I don't know how that Gemfile.lock is invoked or why that dependency isn't the one that's loaded (maybe you can explain that for me).

In any case, running the suggested gem install multipart-post -v 2.2.0 before the gem install gazer .. works, but it seems like it should be unnecssary.

Hello.

I not seeing the same issue when I try this, may I ask what base container you are using?

Thanks.

Ah, we're using python:3.7-slim-buster which looks like it's debian based. I presume this is an us problem then so we can sort it out. Thanks for getting back to us though.
