failed in push to heroku - can't find the error - ruby-on-rails

I'm pushing my rails app to heroku and It fails and I don't know what is the problem, here's the heroku log, knowing that I'm still a beginner
! Warning: Multiple default buildpacks reported the ability to handle this app. The first buildpack in the list below will be used.

Your Gemfile lists the gem bootstrap-sass (= 3.3.7) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of one of them later.
Warning: the running version of Bundler (1.15.2) is older than the version that created the lockfile (1.16.2). We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.

Notes: tried to fix the uglifier by changing production.rb using this answer, but it's not working though
Syntax error when deploying Rails app to Heroku: ExecJS::RuntimeError: SyntaxError: Unexpected character


Solution:
remove the comment line which is start with "#" from any of your .js file
source of answer: ExecJS::ProgramError: Unexpected character '#'


You would use bundle update, to update the version of gem, run gem install bundler
Your application must be up to date because is rely on gems that have deprecated features and about update gems

Anyone could help please?
Thanks in advance

Okay, I solved the issue guys, in the build logs you can see the following:
Gems in the groups 'development' and 'test' were not installed. so I created a group for production gems
group :production do
# Add the gems you need on production here
end
and when I re-deployed, it worked fine.

Rails Heroku App - Precompiling Assets Failed

I recently made a rails app and i've been trying to get it deployed on Heroku. I'm not sure what preventing me from doing so. I have Heroku linked with my Github and am manually deploying from there.
The Github repo is up to date, and the rails app is able to run when I type in
rails s
I tried also deploying manually from my computer as well. I have been following this guide :
https://www.codecademy.com/articles/deploy-rails-to-heroku
Here is the error logs:

Post-install message from i18n:
HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.
But that may break your application.
Please check your Rails app for 'config.i18n.fallbacks = true'.
If you're using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be
'config.i18n.fallbacks = [I18n.default_locale]'.
If not, fallbacks will be broken in your app by I18n 1.1.x.
For more info see:

Post-install message from sass:
Ruby Sass has reached end-of-life and should no longer be used.
* If you use Sass as a command-line tool, we recommend using Dart Sass, the new
primary implementation: https://sass-lang.com/install
* If you use Sass as a plug-in for a Ruby web framework, we recommend using the
sassc gem: https://github.com/sass/sassc-ruby#readme

Tasks: TOP => assets:precompile
(See full trace by running task with --trace)
!
! Precompiling assets failed.
!
! Push rejected, failed to compile Ruby app.
! Push failed

The issue already have a solution in the error description itself
To use ES6 syntax, harmony mode must be enabled with Uglifier.new(:harmony => true)
Solution:
To fix the issue replace the following in config/environments/production.rb
config.assets.js_compressor = :uglifier
with
config.assets.js_compressor = Uglifier.new(harmony: true)
Refer, this issue raised in uglifier https://github.com/lautis/uglifier/issues/127

You could try to precompile the assets before uploading to heroku, with the following command:
RAILS_ENV=production bundle exec rake assets:precompile
And create a new commit and push
git add .
git commit -m "precompile"
git push
Also worth checking: https://devcenter.heroku.com/articles/rails-asset-pipeline

I got multiple errors when trying to install the gems in a rails application cloned from remote repo, here's a screenshot of the error knowing that I'm still junior with RoR, knowing that I tried many answers but nothing worked

Post-install message from paperclip:
##################################################
# NOTE FOR UPGRADING FROM 4.3.0 OR EARLIER #
##################################################
Paperclip is now compatible with aws-sdk >= 2.0.0.
If you are using S3 storage, aws-sdk >= 2.0.0 requires you to make a few small
changes:
* You must set the `s3_region`
* If you are explicitly setting permissions anywhere, such as in an initializer,
note that the format of the permissions changed from using an underscore to
using a hyphen. For example, `:public_read` needs to be changed to
`public-read`.
For a walkthrough of upgrading from 4 to 5 and aws-sdk >= 2.0 you can watch
http://rubythursday.com/episodes/ruby-snack-27-upgrade-paperclip-and-aws-sdk-in-prep-for-rails-5

As this lines says:
Sprockets::FileNotFound: couldn't find file 'turbolinks' with type 'application/javascript'.
turbolinks gem is missing in your gemfile, maybe including it in your gemfile solves the issue.

Pushing from Codeanywhere to Heroku - Precompiling assets failed

So I am a noob to coding. I know some html/css, but that is about it. Anyways, I am following the instructions in this poorly formatted ebook on Ruby on Rails. I have set up a container project on codeanywhere. So far I have fixed all errors up to this point through searching. It seems like a lot of people are having this problem, but I have not found a solution. I am trying to push to my Heroku account. Can anyone figure out what I am doing wrong by looking at the log? So far I have added config.assets.initialize_on_precompile = false to my application.rb file because that was one of the potential fixes. Otherwise, I'm lost.
