推送到Elastic Beanstalk时Rails捆绑错误

Question

I had an app deployed on Heroku and I am currently trying to create the same app on AWS. I've copied my folder, created a complete separated repo on Github and installed ebcli, the setup looks fine.

When I try to run eb deploy, I have this error: [Instance: i-03051e2a022886184] Command failed on instance. Return code: 1 Output: (TRUNCATED)...:in find_spec_for_exe': can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException) from /opt/rubies/ruby-2.5.3/lib/ruby/site_ruby/2.5.0/rubygems.rb:308:in activate_bin_path' from /opt/rubies/ruby-2.5.3/bin/bundle:23:in `'.

I've looked online and it says it comes from incompatibility between your gemlock file bundler version and actual bundler version.

I've tried to change my bundler version to this one, but I gave up and came back to 2.0.1 because I had to install too many dependencies otherwise. I removed the gemlock, bundle again, but I still got the same error when trying to deploy.

With my heroku version, it always worked.

Any idea how to solve that?

Thanks a lot

Answer 1

We moved from Heroku to AWS a few months back as well and it will likely take some some custom scripting to get things to work.

It would help to know more about your EB environment, but I am assuming you are using Ruby 2.5 with Puma on Amazon Linux 2.9.0 (?)

Not sure what bundle version comes with that, But I don't think it's 2.x. so you have to add an .ebextensions file too install your preferred bundled version.

# .ebextensions/01_install_bundler.config

container_commands:
  install_bundler:
    command: “gem install bundler —-version 2.0.0”

End of the day, we are much happier with our AWS environment (lower cost, better performance), but requires more work to get it set up

Answer 2

Actually the problem exists because the bundler version in the eb env is older than the one being used in the project source.

So the solution is to use a bundler version less or equal the eb env installed version.

First uninstalled the current bundler:

gem uninstall bundle

and then install the desired one:

gem install bundler -v 1.16.6
