When I run the command "git push -f heroku", I get the following problem:

! Push rejected, failed to compile Ruby app
To git#heroku.com:tummystuffer.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git#heroku.com:tummystuffer.git'
So I added the gem 'geocoder' inside of my Gemfile, removed Gemfile.lock, ran "bundle install", "git add", "git commit", and pushed again, but got the same exact error.
I tried to solve the problem from this: heroku push rejected, failed to compile Ruby/rails app, but still gave me the same error.
I've ran "gem cleanup" and ran "gem update" as well, but did not work.
Here is my Gemfile:

Answer 1

The error states:
You are trying to install in deployment mode after changing your Gemfile. Run bundle install elsewhere and add the updated Gemfile.lock
to version control.
This basically means you've either not committed your Gemfile.lock, or have not run the bundle install command, which basically rebuilds Gemfile.lock. There's now a conflict which you'll have to resolve using bundle install on your development environment:
$ bundle install
$ git add .
$ git commit -a -m "Geocoder"
$ git push -f heroku

Answer 2

I had the same problem. A simple bundle install solved the problem for me.
After bundle install, git add . and git commit, I pushed the code to heroku master and it worked!
$ git push -f heroku master

Answer 3

I was actually able to solve the issue. I found out I was trying to push the project to another branch (not the master branch). I solved the issue by merging the branch with master branch and pushed it again.

Answer 4

It's an old thread but still relevant... I solved this by doing:
1) in the terminal create a new branch fixes
git checkout -b fixes
2) Delete gemfile.lock
3) In the gemfile replace gem 'squlite3' and gem 'pg' with this
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'pg', '0.20.0'
end
4) run these commands in terminal
bundle update
bundle install --without production
git add .
git commit "Update files for heroku"
git checkout master
git merge fixes
git push -f heroku master
