I am trying to push a rails application to heroku.
When I get to the last step:
git push heroku master
It doesn't work and gives me these errors:
Counting objects: 85, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (74/74), done.
Writing objects: 100% (85/85), 24.38 KiB, done.

-----> Heroku receiving push
! Heroku push rejected, no Rails or Rack app detected.

To git#heroku.com:smooth-dusk-26.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git#heroku.com:smooth-dusk-26.git'
I don't know what I'm doing wrong :(
Here's the answer I got from Heroku and it worked for me (after trying different pg gems, adapters, and everything else on the 10 other posts about this)
1) add the line:
gem 'pg'
to your Gemfile.
2) Run the command bundle install to install the gem into your bundle.
3) Stage the Gemfile and Gemfile.lock changes:
git add Gemfile Gemfile.lock
4) Commit the changes:
git commit -m "Install the pg gem"
5) Redeploy to heroku:
git push heroku master
When you created your Rails application, did you change directory into the directory of the application? You have to perform all the commands from within the application's directory.
rails myapp
cd myapp
I encountered the same errors working through Chapter 1 of Michael Hartl's Rails Tutorial. They were eventually resolved by issuing another git commit command after opening a Heroku account and configuring the SSH keys: git commit -a -m "Heroku recommit"
git push heroku master then succeeded.
I just had the same problem trying to push my app to heroku and none of the above answers fixed it.
I solved the issue by emptying my RVM Gemset with rvm gemset empty, deleting my Gemfile.lock (probably best to just rename it) and reinstalling my gems. Pushing worked fine after this.
For me it was the presence of index.php that fixed it. Heroku seems to check for existence of index.php on pre-commit.
Got the same problem under windows following one of the guides on ror site. After making everything like here http://devcenter.heroku.com/articles/quickstart it was solved.
Seems like problem was because of missing two lines.
cd myapp
git init
Also, if you're on Rails 3.0 make sure you use the cedar stack
heroku create --stack cedar
I went through the Rails Tutorial and didn't have a single problem with Heroku (MAC OS X), but you do have to follow the directions.
First, make sure you add/commit to Git. Then if you're in a -b (branch) you need to checkout into master, then merge the branch. If you've made changes to assets, you need to rake asset:precompile.
If you're having a rack up issue, make sure you have this file => config.ru and the contents should look like this.
# This file is used by Rack-based servers to start the application.
require ::File.expand_path('../config/environment', __FILE__)
run SampleApp::Application
I'm relatively new to Rails and Heroku, but as I mentioned above, if you're following the tutorial's directions, Heroku is a snap and the directions most definitely work. If not, I highly recommend getting started there!

I am trying to push the first version of a Ruby on Rails app to Heroku.
When I run git push heroku master the errors I get are:
remote: -----> Failed to detect app matching no buildpack
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/myapp'
Since no buildpack was detected, I tried to set it manually. When I run heroku buildpacks I get Buildpack URL heroku/ruby, but I still get the same error.
I checked this solution and my gemfile is present, my ruby version in the gemfile is defined and my gemfile.lock has the railties gem.
Heroku logs just regurgitate the errors above so it wasn't helpful
Any suggestions for what else my be wrong?
Did you try putting the putting ruby version number on top of the GemFile.
ruby '<your ruby version>'
the following line above should be at the top of gemfile. Also make sure you have Gemfile and Gemfile.lock files committed, those will be checked upon pushed to heroku servers.
Did you commit the app to the Git Index?
The Gemfile and Gemfile.lock are probably indexed but not yet commited.
You need to have the rails project at the root. If it's not, Heroku will not know the entry point.
So this: somefolder/my_rails_app will not work.
I am having a problem with microposts rendering correctly on heroku, but not on localhost. I am following Hartl's Rails Tutorial guide.
Here is an imgur album showing the issue. The first image is the error(heroku), the second one is correct (localhost).

I cannot for the life of me figure out why this would happen. It almost seems like Heroku is ignoring my CSS.
Here is the github repo:
https://github.com/Mciocca/sample_app
Sounds like one out of three possible reasons:
There's a conflicting stylesheet interfering. Check out app/assets/stylesheets whether there are classes defined twice.
Stack. I see you've placed pg in production in your gemfile, which is good. Heroku runs on Cedar stack - make sure it is. (Creating severe-mountain-793... done, **stack is cedar**)
Not assuming anything, but I've been there several times: make sure you've included recent changes to your repo before pushing to heroku. git add . and git commit -am "brainfart", then git push heroku master <branch>.
And congrats on choosing Rails!
Run bundle exec rake assets:precompile to compile the assets incl. the stylesheets into the public hierarchy that is being used by Heroku.
When done:
git add -A
git commit -m "Precompiled assets" and finally
git push and git push heroku
For better understanding check out the Rails Guides on asset pipelines and the Heroku Guides on assest pipelines.
I was working through the first chapter of the Rails Tutorial. I pushed first_app to heroku. At first I was getting the sqlite3 error (I think). But, I edited the gemfile and pushed it up to heroku again. But, I don't get the same page as on: http://railstutorial.org/ruby-on-rails-tutorial-book#sec:1.4.3 (I think it's supposed to look like Figure 1.11 in section 1.4.3)
Instead, I get this: http://blooming-samurai-546.heroku.com/
It just says:
Heroku | Welcome to your new app!
Refer to the documentation if you need help deploying.
I did something wrong right? Any ideas what?
In your git console try:
git add .
git commit -am "Initial commit"
git push heroku
It looks like you pushed to heroku with nothing so it created an empty directory.
I had this same issue and was very frustrated by it. What solved the issue for me was moving
gem 'sqlite3'
into the block following
group :development, :test
in the Gemfile.
After that, no longer saw these kinds of messages:
remote: ! Failed to install gems via Bundler.
remote: ! Detected sqlite3 gem which is not supported on Heroku:
...
remote: ! Push rejected, failed to compile Ruby app.
in terminal after typing git push heroku or git push heroku master
Hope this helps.
Can’t argue with success.
However, before pushing the master with $ git push heroku master some folks may need to run the following command:
$ git remote add heroku git#heroku.com:your-heroku-url-goes-here.git
as discussed in the “Git Remotes and Heroku” section currently at:
http://devcenter.heroku.com/articles/git
when I push my rails 3 app git heroku master I get this error msg:
-----> Heroku receiving push
-----> Rails app detected

! You'll need to declare it in either .gems or Gemfile.
! See http://docs.heroku.com/gems for details on specifying gems.

I have gem 'rails', '3.0.3' specified in my gemfile, so I am not sure what the issue is....If anyone could help I would really appreciate it. Thanks..
Don't forget that Gemfile is case sensitive. Make sure the file is actually IN your repo. You should also have a Gemfile.lock file too. Which version of bundler are you running?
Have you successfully deployed to Heroku before?
If not you may want to double-check that rails, 3.0.3 is committed to your Git repo just as a sanity check...
I think the problem might be connected with the heroku server type (or idiomatically: stack). The normal stack (called Aspen, I think) is runned by Debian Etch which doesn't support newer versions of Rails (i.e. Rails 3) and neither Sinatra.
To solve the problem you can switch to the Bamboo stack which is runned by Debian Lenny. You can do it by switching the stack as followed:
heroku create yourname --stack bamboo-mri-1.9.2
"yourname" is of course the name of your application. After that it should work as it should.
I am trying to deploy one ROR app on Heroku.
As I typed "git push heroku master", I got this :
-----> Heroku receiving push
-----> Rails app detected
-----> WARNING: Detected Rails is not declared in either .gems or Gemfile
Scheduling the install of Rails 2.3.8.
See http://docs.heroku.com/gems for details on specifying gems.
I wanted to know what it meant especially what was behind the "WARNING" message.
On Heroku's website (http://docs.heroku.com/gems) it's said you can fix this issue with the following instructions :
git add .gems
git commit -a -m "added .gems file specifying framework
git push heroku master
The problem is when i type "git add .gems", I get this :
fatal: pathspec '.gems' did not match any files
What do you think i should do ?
Thanks in advance for your time.
Have been learning Ubuntu, Heroku+ROR for a few days
OS : Ubuntu
Ruby : 1.8.7
Rails : 2.3.8
You have to create the .gems file first, if it doesn't exist already:
$ touch .gems
$ git add .gems
$ git commit
