Deploy to dokku fails because of ruby-buildpack + bundler? - ruby-on-rails

I'm deploying a rails app to dokku. The Versions are:
ruby 3.1.2
bundler 2.3.26 (on my development machine)
gem 3.3.22 (on my development machine)
when i try to deploy to dokku, the heroku ruby buildpack is used, and I get
the following output:
-----> Ruby app detected
-----> Installing bundler 2.2.21
-----> Removing BUNDLED WITH version in the Gemfile.lock
-----> Compiling Ruby/Rails
-----> Using Ruby version: ruby-3.1.2
-----> Installing dependencies using bundler 2.2.21
Running: BUNDLE_WITHOUT='development:test' BUNDLE_PATH=vendor/bundle BUNDLE_BIN=vendor/bundle/bin BUNDLE_DEPLOYMENT=1 bundle install -j4
[330, #<Thread:0x00007fc0e8b43c90 run>, #<NameError: uninitialized constant Gem::Source
(defined?(#source) && #source) || Gem::Source::Installed.new
^
The crazy thing: I have another app with the same configuration where it works:
-----> Ruby app detected
-----> Installing bundler 2.2.21
-----> Removing BUNDLED WITH version in the Gemfile.lock
-----> Compiling Ruby/Rails
-----> Using Ruby version: ruby-3.1.2

Running: BUNDLE_WITHOUT='development:test' BUNDLE_PATH=vendor/bundle BUNDLE_BIN=vendor/bundle/bin BUNDLE_DEPLOYMENT=1 bundle install -j4

My research so far:
This seems to be the problem described here as an issue with bundler 2.3.7 first described in February 2022. But my buildpack uses bundler 2.2.21, so it should not be affected?
The newest ruby-buildpack from heroku seems to have been released in 2021?
Can this be right?
This fixed the problem for one app:
upgrade to ruby 3.1.3 (by editing ruby version in Gemfile and in .ruby-version)
bundle install
bundle lock --add-platform x86_64-linux
After one successfull install I could also roll back to the old ruby version, before upgrade, and successfully install that.
How? Why? What is going on here?
Now another app that used to work stopped working.

Purging the dokku build cache fixed the problem:
dokku repo:purge-cache
correction: this helped for some applications, not for all

Heroku Deployment - Rails 6.1.3 - Bundle install failing - Gemfile.lock platform addition

I am trying to deploy a simple Ruby on Rails web app using Heroku. When I attempt to deploy the web app, I get a bundler error saying the correct platform is not within the Gemfile.lock
Here is the build log:
-----> Building on the Heroku-20 stack

I attempted to add the platform to the Gemfile.lock file but was hit with this dependency error:

Resolving dependencies.........
Bundler found conflicting requirements for the Ruby version:
In Gemfile:
Ruby (~> 3.0.0.0)
capybara (>= 3.26) was resolved to 3.35.3, which depends on
nokogiri (~> 1.8) was resolved to 1.11.1, which depends on
Ruby (< 3.1.dev, >= 2.5)
I have not found a successful fix online. There were some suggestions to remove the Gemfile.lock file but that broke my local server which makes sense. I'll be happy to provide more information if necessary.
running the following command should fix your issue.
bundle lock --add-platform x86_64-linux
bundle install
git add . ; git commit -m fix

Heroku rails deployment issues

I'm trying to push my rails app to deployment via Heroku and whenever i do, i'm getting thrown this error:
Detected buildpacks: Ruby,Node.js

Jruby seems to be playing into this somewhere but i just can't figure it out. Any help would be appreciated.
Answer has been solved as of today. The problem was that somewhere along the line, jruby got included in the list of gem dependencies and snowballed into everything else. In order to fix the problem, I needed to remove all instances of jruby from all folders within the app and it was able to compile properly and deploy.

Deployment failed on heroku - Ruby on Rails

Im having a problem to deploy a new version of my Ruby on Rails app on heroku.
Heroku build log:

Important notes:
I haven't changed the Ruby version;
I've tryed to deploy another Ruby on Rails app, and realize that i'm not able to deploy any Ruby on Rails app.
Anyone with the same problem or any idea to help?
Apparently, the problem is related to a buildpack version released at July, 13. I solved the issue removing this update and specifying the version of Ruby buildpack
$ heroku buildpacks:remove heroku/ruby
and then
$ heroku buildpacks:set https://github.com/heroku/heroku-buildpack-ruby#v217

Install local gems via bundle on heroku not working

I'm trying to install my app to heroku. But I'm having an issue with a gem. Its a private gem and we don't have a private gem server setup, so I've cloned the gem locally as a submodule inside the app.
When I push to heroku I get this error:
! Warning: Multiple default buildpacks reported the ability to handle this app. The first buildpack in the list below will be used.

When I removed the locally install gem it all worked fine.
So strong hunch is that bundler 1.15.2 handles local gems differently and it's causing a conflict.
In my Gemfile, not inside any group, I have gem 'portkey', path: './gems/portkey/'
At the top of my Gemfile.lock I have
PATH
remote: gems/portkey
specs:
portkey (0.1.10)
bitly
omniauth-google-oauth2 (~> 0.5.3)
rails (~> 5.2.1)
rebrandly
shortener (~> 0.8.0)
will_paginate
Heroku doesn't support bundler 1.16.2 yet afaik
I'm using rails 5/ruby-2.5 and I don't seem be able to downgrade bundler to 1.15.2 and generate an older version of the lockfile
I can't easily make this gem accessible any other way.
I'm stumped how I can make the install of this gem work, and suggestions would be greatly appreciated.
Had a similar issue, solved by upgrading to Bundler 2.0.1 (which is now supported by Heroku).
For 1.x version they still use 1.15.2 though.

Downgrade/Revert Ruby Version on Heroku

I recently updated my Heroku app from Ruby 2.3.1 to 2.4.0, but I now need to revert back to version 2.3.1.
To Update:
I changed the version in the Gemfile from 2.3.1 to 2.4.0. Everything went fine, but I need to go back to 2.3.1 because of problems specific to me with 2.4.0
To Revert:
I've tried changing the version back to 2.3.1 in my Gemfile (as ruby "2.3.1") but it just throws the bundler error Your Ruby version is 2.4.0, but your Gemfile specified 2.3.1
How do I change my Ruby version back to 2.3.1 on Heroku?
Here is the error on deployment:

I figured it out. Here are the steps

Change the Ruby version from 2.4.0 to 2.3.1
Verify the version is 2.3.1 with ruby -v
Run gem install bundler && gem install rails
Run bundle install
Commit the Gemfile and Gemfile.lock and push to Heroku
