I got this error message (copied below) after trying to push to Heroku. I initially set up a facebook canvas app and selected the hosting on heroku options. It gave me a heroku url, which I added as a remote on the app I was developing on my machine
heroku git:remote -a desolate-springs-1684
But when I pushed, I got this error
error: failed to push some refs to 'git#heroku.com:desolate-springs-1684.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.
localhost:nhl michaelmitchell$
So I did
git push -f heroku master
But now I apparently have to do a 'git pull'. However, what do i put after the 'git pull'? The name of the heroku url? or something else?
Forcing your git push was not a good idea because you lost any commit that was done by you or other collaborators you were missing on your working copy.
Before pushing, you should have either merged or rebased the upstream changes into your local working copy.
To merge the changes locally
$ git pull heroku master
$ git push heroku master
To rebase the changes locally
$ git pull --rebase heroku master
$ git push heroku master
BTW, now that you have pushed your changes, you actually don't need to do anything else. The remote repository already contains all your changes.
If for whatever reason the $ git status command is returning outdated references, simply run
$ git pull heroku
to fetch all the remote changes. Please note that unless you specify a target branch (or you have the tracking branch enabled), git pull will simply download (and not merge) the upstream changes.
Also note that Heroku should not be considered a git hosting. It means that it's extremely uncommon to perform a git pull from Heroku. Instead, you should use a git hosting (such as GitHub or BitBucket) to store your repository and only perform push to Heroku to deploy the application.
That error basically means that there is code in the repo that is newer than the code you're trying to push to it.
you have to do a pull and update your own working repository then push again, or just force a push
git pull heroku master
As a side note, if you aren't familiar with all the git commands, I would recommend you use a GUI as it may make the whole process a lot less overwhelming.

I'm really confused -- I have made some changes to my app, and need to push the changes to heroku.
I have run git add . git commit -m "message", and git push origin master (all my work is on master branch), and get the message saying Everything up to date.
HOWEVER, when I run git push heroku master immediately after, I get a message saying Updates were rejected because the tip of your current branch is behind its remote counterpart. Integrate the remote changes (e.g. 'git pull ...') before pushing again.
When I run git pull origin master, it says Already up-to-date. So I'm really baffled as to what is behind here, or what I need to do!
use source-tree and check the file status and then try to push.

Used the command git pull as mentioned in hint the response was Already up-to-date.
What could be the reasons behind this error? and is this the correct way to push on heroku
By doing git push heroku mybranch:master, you are telling git to take your local mybranch branch and merge it with the remote master branch (remotely stored on your heroku repo).
You get an error because master is ahead of mybranch in terms of commits.
Consider this example:
master: --------b---------m---------
mybranch:........\-c--c--/...........
At some point, you branch (b) master into mybranch, commit (c) some code to the branch, and merge (m) it back to master.
Now consider this example:
master: --c-----b---c-----m---c--
mybranch:........\-c--c---/.......
It is pretty much the same scenario but while you were committing code to mybranch, someone updated master by committing some other code. If you were to merge back mybranch into master, you would risk causing conflicts between your code and the new code contained in master, thus Git refuses to do the merge. First, you have to update your local branch with the new version of master and then only Git will allow you to push.
In short:
- git pull heroku master:mybranch
- resolve potential conflicts
- commit modified files
- git push heroku mybranch:master
Now about Heroku, you are supposed to always push code like this: git push heroku master (considering you are on the master branch locally). What you should do to avoid things like git push heroku mybranch:master is, when you finish working on a branch, always merge your changes to master and then (after verifying that everything is working) push master to heroku.
See this resource for a simple git workflow that seem to be what you are looking for: https://www.atlassian.com/git/workflows#!workflow-feature-branch
Everything is centralized in master eventually, and you can then regularly push master to heroku (ideally you would push once for every version of your app)
From the hints it seems that you have not pushed your latest changes to your remote repository.if you have done a pull and pushed again maybe you have removed files in your local repository that you did not remove in your remote repository.try doing a git add --all and then commit and push the changes.
I have started learning Ruby on Rails and Git.
Whenever I try to push any changes to my remote repo on Github, I encounter the following error:
C:\Sites\first>git push origin master
To git#github.com:piy9/Twitter_clone.git
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'git#github.com:piy9/Twitter_clone.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Merge the remote changes (e.g. 'git pull')
hint: before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
NOte: I have added all the files in the directory and committed the changes. I have not created any separate branches using pull or checkout.
I am not asking for a solution to the problem.
doing
git push -f or
git push origin +HEAD
worked for me.
What I want to know is, why am I getting the error while trying to push to the original branch.
follow this and get everything works....
git branch production
git checkout production
#do some code changes
git commit -am "some desparate code changes to try fix heroku"
git push heroku production:master
Note: this will get your work done and will leave your previous branch.
or you can try this one also git push heroku +master
Looks like remote branch is ahead of yours, which means it contains something your local branch does not have. You may easily see commits on remote branch since when local branch was created or updated (assuming you run "git fetch origin/master" to fetch remote changes first):
git diff HEAD...origin/master
The output will answer your question why you are getting the error.
Now, my guess about the reason of the problem you have is that either someone has access to remote and pushed something, or you modified something using github editing interface and committed since last checkout/pull/merge. Using forced push as you did is not a good approach and it messes the history, it basically overwrites the remote branch with your copy, ignoring any remote changes.
I am collaborating on a project and cloned the repo from Github, made some changes and pushed to Heroku. Now the cloned app had all of its keys and passwords hardcoded, not in ENV variables.
So I created ENV variables, added the file to .gitignore. So this app still has these keys in the commit history. What I have done now is have the author create a new repo on Github, remove .git file from original app and push new code to new repo.
So now I have cloned the new app, added a new remote the the Heroku app.
heroku git:remote -a myapplication
My issue is I cannot push the new app to the existing Heroku app. When I do I get:
error: failed to push some refs to 'git#heroku.com:myapplication.git
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Merge the remote changes (e.g. 'git pull')
hint: before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
So a git pull says everything is up to date.
git remote -v outputs
heroku git#heroku.com:myapplication.git (fetch)
heroku git#heroku.com:myapplication.git (push)
origin git#github.com:author/myapplication.git (fetch)
origin git#github.com:author/myapplication.git (push)
What can I do to push the new application to the existing heroku app?
Update
I ran
git push -f heroku master
which pushed but I had error
you have not declared a Ruby version in your Gemfile.
To set your Ruby version add this line to your Gemfile:"
ruby '1.9.2'"
I've never had to specify before, and now all the original config vars that where set are no longer stored in Heroku.
git pull would pull by default from GitHub, which has all your commits already.
You might need to:
git pull heroku
clean-up the files (if the merge brings back the hardcoded values)
push to origin
push to heroku through the heroku command.
Git uses the concept of tracked branch to know which remote branch is linked to a local branch.
In your case, you probably have your local branch (I suppose it's master) linked to origin/master. So, when you do a git pull, Git is trying to get new stuff from git#github.com:author/myapplication.git, which is not the wanted behavior.
You have to change your tracked branch using :
git branch --set-upstream-to heroku/my_branch
Then, you can do a git pull which will now have the wanted behavior. Then just push to heroku, as you always do.
I'm using Heroku and have a Rails app that is stable (production env), so I wanted to create something new where I can have quality assurance env where I can see how the changes will work on Heroku (as well as aggregating enhancements for releases) without always pushing to my production app.
So what I did was create a new Heroku app, and also create a new branch locally (dev). My intention was to merge dev into master locally after I tested the change on my new Heroku QA app, and then push to Heroku production from my master branch.
My approach might be a bad one with my landscape, I'm a newbie, so this was just my best guess at how to do this.
But when I pushed my dev branch to my new QA app, it worked for pushing to a dev branch of the QA app, but not the master. So I couldn't see (and test) my changes on the new QA app. It seems to be telling me that I can only push the master branch to the master of my QA app, since I pulled already and everything was already up-to-date, but I receive this error:
Pushing to git#github.com:foobar/QA.git
To git#github.com:foobar/QA.git
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'git#github.com:foobar/QA.git'

hint: its remote counterpart. Merge the remote changes (e.g. 'git pull')
hint: before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
Can someone please help me figure out what I'm doing wrong - either with my environments or with Git? Thank you.
Try pushing with the -ff (fast-forward) option: git push heroku master -ff (replace heroku with the actual name of heroku remote).
Heroku apps only run off of the master branch of the app repository (local to Heroku). If you want to deploy a branch to Heroku which isn't the master branch of your local repo, then you need to specify it. In your case it would be something like git push qa-remote dev:master (replace qa-remote with the actual name of the remote to your QA app), which says push my local dev branch to the master branch on qa-remote.
When you push like that for the first time, you'll likely need to add the -f flag to force push (non-fast-forward). Subsequently you should be able to push without the -f flag, as long as your local branch is up-to-date.
Use the following command to push the update forcefully git push -f heroku master
