remote rejected master -> master (pre-receive hook declined)

Question

I\'m working in rails 3.2 and I receive an error when I try to push to heroku:

 git push heroku master
Counting objects: 496, done.

Answer 1

If you run $ heroku logs you may get a "hint" to what the problem is. For me, Heroku could not detect what type of app I was creating. It required me to set the buildpack. Since I was creating a Node.js app, I just had to run $ heroku buildpacks:set https://github.com/heroku/heroku-buildpack-nodejs. You can read more about it here: https://devcenter.heroku.com/articles/buildpacks. No pushing issues after that.

I know this is an old question, but still posting this here incase someone else gets stuck.

Answer 2

If you get this error and the terminal is not descriptive enough to help you, Heroku might be able to tell you what is wrong through their website. Try the following:

1. log in to Heroku and go to your dashboard;
2. select the problem application from the list; and,
3. check the build logs under the "Activity" tab.

In my case, I had accidentally ignored my Gemfile.lock.

Answer 3

simple answer

$ heroku config:set DISABLE_COLLECTSTATIC=1

after

$ git push heroku master

Answer 4

I had the same issue.

Look at your git ignore and check if .env is not ignored.

It was my problem and resolved to my case.

Answer 5

Check the following

1. Make sure you add all the files and directories needed to be tracked are added using git status [You have done this]

   $ git status

2. If not added then add them using **git add . ** [You have done this]

   $ git add .

3. Bundle all gems and you will have Gemfile.lock

   $ bundle install
   $ git add Gemfile.lock
   $ git commit -am "Added Gemfile.lock"
   

4. Push it to heroku

$ git push heroku master

Your push should work

Answer 6

The package setuptools/distribute is listed in requirements.txt. Please remove the same.
