Not able to deploy using Ruby 2.6.0-rc1

[everton]

Two days ago it was announced that "Ruby 2.6.0-rc1 is now available":

https://devcenter.heroku.com/changelog-items/1534

But when I try to deploy Rails applications using (locally) with "Bundler version 1.17.1" it fails with the error:

"Could not detect rake tasks ensure you can run $ bundle exec rake -P against your app"

Using the build in bundler (which now is part of Ruby, since 2.6.0-preview3), the deploy fails with error:

You must use Bundler 2 or greater with this lockfile.

So, I was not able to deploy using 2.6.0.... is there anything to workaround this? How am I supposed to deploy using the newest Ruby?

Hi, I'm the maintainer of RubyGems and Bundler. Please give the logfile of its errors.

And can you try again after re-generating Gemfile.lock file(Removing BUNDLED WITH line or rm Gemfile.lock?

remote:        ##################################################
remote:        
remote:        Paperclip is now compatible with aws-sdk-s3.
remote:        
remote:        If you are using S3 storage, aws-sdk-s3 requires you to make a few small
remote:        changes:
remote:        
remote:        * You must set the `s3_region`
remote:        * If you are explicitly setting permissions anywhere, such as in an initializer,
remote:          note that the format of the permissions changed from using an underscore to
remote:          using a hyphen. For example, `:public_read` needs to be changed to
remote:          `public-read`.
remote:

You need to remove the line BUNDLED WITH and the line right after it. That's a short term workaround.

For now I recommend using Ruby 2.5.3. This issue is being remediated in Ruby by @hsbt. You can try 2.6.0-rc2 once it is released.

[everton]

Thanks @schneems, I'm able to deploy using the suggested workaround (removing the BUNDLED WITH lines from Gemfile.lock).

I will keep this issue open because I don't know if a workaround is considered a "fix" to it, but for me it is closed.

Thanks and we will be willing to test the 2.6.0-rc2 as soon as it get released.

[Petercopter]

I'm using this buildpack with 2.6.0 and RUBYOPT=--jit. It seems to be working for me.

[sunnyrjuneja]

Just as a heads up, I think this issue can be closed! I'm able to successfully deploy 2.6.1.

[amitpatelx]

I am not sure it is right place to ask about pack. I am building pack for a rails application and try to run locally but I get following error.

I am using Rails 5.2 with Ruby 2.5/2.6 and postgres.

[atstockland]

I am experiencing a very similar issue with ruby 2.7.0preview2, rails 6.0.0, Bundler version 2.1.0.pre.2. Removing BUNDLED_WITH did not get me past the error.

[hsbt]

@atstockland It's no issue of Bundler related BUNDLED_WITH. Maybe it was fixed at rails/rails@cf4a6c1

[atstockland]

I kinda thought the same thing and upgraded my Gemfile to use the most recent rails commit cb740af. No change after updating rails. Is this possibly an issue in this ruby Buildpack, or am I barking up the wrong tree?

[hsbt]

There is no way to resolve your issue before releasing Rails 6.0.1.

[atstockland]

What is the cause of this issue? I tried reverting my code/setup to the last successful push, but push still fails with the same error. Is there anything I can do to get Heroku push to work again...or, do I just have to wait it out for 6.0.1?
