Trying to start up a brand new rails project with heroku, followed the steps in https://devcenter.heroku.com/articles/getting-started-with-rails5 and https://devcenter.heroku.com/articles/getting-started-with-rails6. Both times when I try to push to heroku master, I get
remote: -----> Detecting rake tasks
remote:

I've tried to surround the bootsnap/setup with a rescue, and it still hits this block.
In my case, I have 3 bundler versions installed:
gem list bundler
*** LOCAL GEMS ***
bundler (2.2.5, default: 2.1.4, 1.17.3)
Though 2.1.4 being the default, it seems it is not what being used when I bundle install.
I run bundle _2.1.4_ install and then it updates my Gemfile.lock.
# git diff
BUNDLED WITH
- 2.2.5
+ 2.1.4
Then the problem was gone when I git push heroku main. I found these links helpful in troubleshooting my issue: Heroku Rails build failing due to Bootsnap and Rake issues and How to switch bundler version?.
Found a solution, In Gemfile.lock I switched RUBY VERSION to ruby 2.6.6p146 and BUNDLED WITH to 1.17.3

I'm trying to run a Rails app on Ruby 2.7.1 on Heroku. Everything worked fine, then I changed something in my Gemfile to use Ruby 2.7's numbered parameters, and now the deploy fails with this error message:
remote: -----> Build succeeded!
remote: -----> Ruby app detected
remote: -----> Installing bundler 2.0.2
remote: -----> Removing BUNDLED WITH version in the Gemfile.lock

It works fine locally and I've been using the same code in a few other Rails apps and deployment was never a problem.
Due to the error Undefined local variable or method '_1' for Gemfile. I assume a Ruby version < 2.7 is used when running bundle install.
The app itself runs fine on Ruby 2.7.1 though:
$ heroku run "ruby -v"
Running ruby -v on ⬢ myapp... up, run.7979 (Free)
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux]
There are a few other similar questions here on SO, but they all deal with Heroku not respecting the Ruby version set in Gemfile or .ruby-version, which is not the problem for me, just during bundle install it seems to use a different Ruby version for some reason...
Is there any way to debug this further, or force Ruby 2.7 even during bundle install on deployment?
I have a Ruby on Rails and Redux/React app I have already pushed dozens of times to heroku via "git push heroku master" and it builds correctly. I recently tried to create a staging environment. After setting the remote, I run
git push staging master
And the webpack portion builds correctly, but once Heroku tries to build the Rails portion I get this error.
remote: ! Could not detect rake tasks
remote: ! ensure you can run `$ bundle exec rake -P` against your app
remote: ! and using the production group of your Gemfile.

remote: ! To install the version of bundler this project requires, run `gem install bundler -v '2.0.1'`
To create the staging environment, I ran
heroku create --remote staging
in the root folder of the project.
I also have tried updating the bundler.
bundle update --bundler
&
gem install bundler:2.0.1
I tried precompiling assets as well, but nothing.
RAILS_ENV=production bundle exec rake assets:precompile
I ran
bundle exec rake -P
as suggested, but that did not fix it as well.
Another thing is when I push successfully, in the logs it shows I am using a different ruby version
Using Ruby version: ruby-2.3.4
remote: -----> Installing dependencies using bundler 2.0.2
In the staging logs it shows
Using Ruby version: ruby-2.5.5
remote: -----> Installing dependencies using bundler 2.0.2
Not sure if that helps. But any possible solutions can help!
Thanks!
The solution to issues like these it to ensure all environments (development, staging, production, CI) share the same Ruby version. This will make development and testing much more predictable.
Specify your Ruby version in the Gemfile (this build worked with Ruby 2.3.4, so that's what we'll use):
# Gemfile
ruby '2.3.4'
I'm facing errors I can't handle while trying to deploy an app to Heroku (it's my first time).

RUBY VERSION
ruby 2.6.1p33
BUNDLED WITH
2.0.1
I've tried several solutions, like:
running RAILS_ENV=production bundle exec rake assets:precompile (see here)
adding the RAILS_SERVE_STATIC_FILES key (same)
upgrade Ruby to 2.6.3 (see here, can't find 2.6.3 with rbenv nor rvm)
I believe it might be due to this issue. Am I concerned by this point ?
2) When using binstubs to run a command instead of bundle exec the wrong
version of Bundler can get activated when using Ruby 2.6.x. This bug
is reported to Ruby Core and will be fixed when Ruby 2.6.3 is
released.
In the short term, the workaround is to ensure all commands in the
Procfile and app.json are prefaced with bundle exec. For example:
web: bundle exec bin/rails server -p $PORT -e $RAILS_ENV
worker: bundle exec sidekiq -C config/sidekiq.yml
As a newbie I feel really lost, could anyone help me on this ?
Thanks for your time
SOLUTION: found here removing BUNDLED WITH and the following line in Gemfile.lock
There are known issues with Bundler 2 on Heroku, including this one:
A Gemfile.lock that specifies bundler 2.0.2 does not work with bundler 2.0.1
If you attempt to deploy an app that uses bundler 2.0.2 onto the Heroku platform with bundler 2.0.1 you may get this error:
`find_spec_for_exe': can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)
This is due to a bug in the Rubygems bundler version checking code. To avoid this issue, upgrade your Ruby version. It is fixed in 2.5.5+ and 2.6.3+. If you do not update, your Ruby version then every new release of Bundler 2.x will trigger this issue.
Upgrade Ruby to at least version 2.6.3 locally, update the ruby version in your Gemfile, bundle install, commit the changes, and redeploy.
UPDATE: now using Ruby 2.5.5 and Bundler 2.0.2, still getting the error:
/app/tmp/buildpacks/<long hash>/lib/language_pack/helpers/rake_runner.rb:106:

I have run gem install bundler:2.0.1 successfully in this app's root directory. My $GEM_PATH does not include vendor/bundle/ruby/2, and I don't know if altering it is the solution. If so, does that mean I need to alter it locally or remotely? If locally, is it done the same way as normal environment variables, or is there a special Rails setting I need to change?
I have tried the suggestion in the accepted answer here:
heroku push error: "Could not detect rake tasks"
but that made no difference.
My problem also seems to be similar to the (unanswered) question here:
Can't Push Rails Project to Heroku
Searching the Heroku Help Center didn't seem to yield any results, either.
Any guidance about what I should do?

Upgrade Ruby to version 2.5.5+ or 2.6.3+ locally, update your Gemfile accordingly, and re-run bundle. Commit the changes to your Gemfile and Gemfile.lock, then deploy again.
I am trying to push a rails 5 app to Heroku and I believe that I followed the instructions on the Heroku page:
https://devcenter.heroku.com/articles/ruby-versions
$ ruby --version
ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]
$ cat Gemfile
.....
ruby "2.3.1"
$ heroku run bash
$ env | grep PATH
PATH=/app/bin:/usr/local/bin:/usr/bin:/bin
$ git push heroku master
remote: Compressing source files... done.
remote: Building source:
remote:
remote: -----> Ruby app detected

which terminates with the error:

remote: Running: rake assets:precompile
remote: rake aborted!
remote: NoMethodError: undefined method `symbolize_keys' for # <String:0x007fac0655feb0>

Which I guess it is because it is using 2.2 and not 2.3.
The version in /bin is 1.9.3 so in case it would not find any, it should use 1.9.3 and not 2.2.4.
The error message above was fixed with the help of spickermann. Removing the secret.yml file from git tracking allowed the app to be deployed without errors.
Still, the wrong Ruby version persists and Heroku even returns a warning at the end:
remote: ###### WARNING:
remote: You have not declared a Ruby version in your Gemfile.
remote: To set your Ruby version add this line to your Gemfile:
remote: ruby '2.2.4'
remote: # See https://devcenter.heroku.com/articles/ruby- versions for more information.
Any advice about what else can be done?
Thank you!
Your deployment fails because your config/secret.yml is not in the expected format. It expects a nested hash like this in production environment:
production:
secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>
Your config/secrets.yml returns a string for the key production. Therefore the deployment fails and you were never able to deploy you new version.
