failed to push some refs to [email protected]
GitHerokuGit SvnGit Problem Overview
I am getting this error when I am trying push my files into heroku rep.
Ive set autocrlf = false already in gitconfig but this problem is still there. i have also tried this solution here but no gain.
Any suggestion is this possible that git is still using old config setting if yes then how can I refresh it.
Thankyou
C:\myapp>git push heroku
To [email protected]:myapp.git

error: failed to push some refs to '[email protected]:myapp.git'
To prevent you from losing history, non-fast-forward updates were rejected
Merge the remote changes (e.g. 'git pull') before pushing again. See the
'Note about fast-forwards' section of 'git push --help' for details.

Git Solutions
Solution 1 - Git
This error means that the upstream repository has made commits that would be lost if you were to push. First do a "git pull" to merge, and then push again.
Solution 2 - Git
In Heroku,you may have problems with pushing to master branch. I just had to start a new branch using
git checkout -b masterbranch
and then push using
git push heroku masterbranch
please try as above!
Solution 3 - Git
Try Using
git push heroku main
instead of
git push heroku master
Reason: Because the default starting branch of git has been changed from master to main that's why your git command is not recognizing master branch and giving you ref error
Solution 4 - Git
Execute this:
$ rake assets:precompile
$ git add .
$ git commit -m "Add precompiled assets for Heroku"
$ git push heroku master

I'm the only person working on my app and only work on it from my desktop, so the possibility that I managed to get the heroku repository above dev didn't make sense. BUT! I recently had a Heroku support rep look into my heroku account for a cache issue involving gem installs and he had changed something that caused heroku to return the same error as the one listed above. A git pull heroku master was all it took. Then I found the reps minor change and reverted it myself.
Solution 6 - Git
I had the same problem, the solution was
in my branch, called "testBranchSuper"
i use
git checkout -b main
and then i use
git push heroku main
Solution 7 - Git
If you want to push commit on git repository, plz make sure you have merged all commit from other branches.
After merging if you are unable to push commit, Use the push command with -f
git push -f origin branch-name
Where origin is the name of your remote repo.
Solution 8 - Git
Make sure you’re pushing the right branch. I wasn’t on master and kept wondering why it was complaining :P

In case I was not the only beginner that used someones 'FULL STACK OVERMEGASUPER EASY AND COOL' Udemy course, I'm writing this post (and in order to add to the list of possible solutions). I had the following error:
remote: -----> Build
remote: Running build
remote:
remote: > shop@1.0.0 build /tmp/build_cb8c8cb5
remote: > cd frontend && npm install && npm run build
remote:
remote: sh: 1: cd: can't cd to frontend
remote: npm ERR! code ELIFECYCLE
remote: npm ERR! errno 2
remote: npm ERR! shop@1.0.0 build: `cd frontend && npm install && npm run build`
remote: npm ERR! Exit status 2
remote: npm ERR!
remote: npm ERR! Failed at the shop@1.0.0 build script.
remote: npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
remote: ! Push rejected to shop.
remote:
To https://git.heroku.com/shop.git
! [remote rejected] main -> main (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/shop.git'
I tried almost everything that was offered by other users. Nonetheless, nothing solved my issue. Then, I finally got nosy enough to look into the logs (for some reason I resorted to the internet right off the bat).
The solution was as follows:
- open package.json and remove "build" line in "scripts";
- git add .
- git commit -your message-
- git push heroku main
This time, build succeeded. It was a very silly mistake. Terminal told me what was wrong but I did not notice it.

For anyone arriving here from a Google search with the same error message. Also be aware that you can have a problem if you are using sqlite3
Solution 11 - Git
On my case clearing buildpacks worked
heroku buildpacks:clear
Solution 12 - Git
For me force with push operation worked.
git push heroku master --force
Case - when pushed commit from current branch was removed(commit was pushed to remote repository).
Solution 13 - Git
It would appear that you are not fully up-to-date. You would need to do a git pull and either "--rebase" or let it merge into your set.
After this, you should then be able to push, since it would be a 'fast-forward' change that wouldn't remove history.
Edit: example command list
git pull
git push
Solution 14 - Git
I was getting this error because I added a line to my requirements.txt file that had an error:
simplejson=2.6.2
There was only one = and there should be two:
simplejson==2.6.2
Correcting this fixed the error.
Solution 15 - Git
I followed the following steps and it worked for me.
- Please take a copy of your (local) changes.
fetch heroku reset --hard heroku/masterThen try to 'git push heroku'.
Solution 16 - Git
Another issue could come from the use of backticks, those are not supported by the compiler (uglifier).
To fix it, replace config.assets.js_compressor = :uglifier with config.assets.js_compressor = Uglifier.new(harmony: true).
Solution 17 - Git
There is one more subtle reason why this might happen. If you added some new packages to your app or updated existing packages, remember to update your requirements.txt file as well.
pip freeze > requirements.txt
Then you can continue with the usual process for pushing your repository
git add .
git commit -m "Some changes"
git push heroku master
Solution 18 - Git
For me it started working after setting global username/email.
To set your global username/email configuration:
- Open the command line.
- Set your username:
git config --global user.name "FIRST_NAME LAST_NAME"
- Set your email address:
git config --global user.email "[email protected]"
- Commit
git commit -m "comment"
- Push to heroku
git push heroku master
BOOM! It worked (atleast for me)
Solution 19 - Git
Just switch the branch to main, It will surely work, and delete the project from Heroku remote. Delete all branches from local and use only one "main".
For reference: https://help.heroku.com/O0EXQZTA/how-do-i-switch-branches-from-master-to-main
Solution 20 - Git
If your heroku project root is in a different directory than your git branch root, use this:
git subtree push --prefix path/to/root heroku master
Solution 21 - Git
I got a similar error. How I fixed mine was to change to command from $ git push heroku master to $ git push heroku main.
It turns out that my git repo was in the main branch instead of the master. So if you are using the wrong branch it will affect you.
Solution 22 - Git
It is probably due to an Outdated yarn.lock file
Just run the following commands
yarn install
git add yarn.lock
git commit -m "Updated Yarn lockfile"
git push heroku master
Solution 23 - Git
In my case, I had an invalid package name. I wasn't able to pick up on the error code right away, because I didn't scroll up far enough, but the error was:
remote: $ NPM_CONFIG_PRODUCTION=false npm install --prefix client && npm run build --prefix client
remote: npm ERR! code EINVALIDPACKAGENAME // <-- this was hard to find
remote: npm ERR! Invalid package name "react-loader-spinne r": name can only contain URL-friendly characters

I had same problem, and I resolved it by doing this:
heroku config:set DISABLE_COLLECTSTATIC=1
It was a django project on python 3.7
Solution 25 - Git
I was facing this issue while deploying a django app on heroku.
In my case the requirements.txt, Procfile and runtime.txt files were present in a subdirectory. Moving them to the root directory of the repository solved the problem.
Heroku is specifically looking for requirements.txt in the root directory to setup the python environment.
P.S :
If heroku is unable to reach till the wsgi file residing in the subdirectory, solve it by referring below thread -
Solution 26 - Git
Also, make sure your branch is clean and there is nothing unstaged you can check with git status stash or commit the changes then run the comand
Solution 27 - Git
I had similar issue where local build was working fine however when I push my branch onto heroku it would fail to build. Issue was that I had some devDependencies in my package.json which were not installed during npm install which was causing my build to fail.
If you need access to packages declared under devDependencies in a different buildpack or at runtime, then you can set NPM_CONFIG_PRODUCTION=false or YARN_PRODUCTION=false to skip the pruning step.
Also you can move you devDependencies into dependencies...

When I tried git pull heroku master, I got an error fatal: refusing to merge unrelated histories.
So I tried git pull heroku master --allow-unrelated-histories and it worked for me
Solution 29 - Git
I'm following this tutorial from freeCodeCamp and ran into the same issue.
$ git push heroku master no longer works, because GitHub is using more inclusive language as of October 2020 and changed their branching language to use main instead of master.
This command works instead:
$ git push heroku main
Solution 30 - Git
just change the branch of heroku by below command:
git checkout -b main
Its worked for me 100%
Solution 31 - Git
In my case, I did the following to fix this issue:
- Delete package-lock.json
run npm installgit add .git commit -m 'dependencies updated.'git pushgit push heroku main
