Heroku does not see my Procfile and begins installing the wrong version of py.
I'm trying to upload an extremely basic flask app using Heroku. As per other suggestions on SO, I've created my Procfile, runtime.txt, and requirements.txt using the command line, rather than through an editor. I've also ensured that they are located in the base git directory. When I enter
$ git push heroku master
I get the following:
remote: Compressing source files... done.

Thanks.
Figured it out. The Procfile was in my .gitignore, stupidly added by me.
Sidenote: the app wouldn't deploy at all because I was pushing from the wrong branch.
My guess is you forgot to add and commit your Procfile to git.

You'll need to use at least an empty composer.json in your
application.
$ echo '{}' > composer.json
$ git add composer.json
$ git commit -m "add composer.json for PHP app detection"
If you also have files from other frameworks or languages that could
trigger another buildpack to detect your application as one of its
own, e.g. a package.json which might cause your code to be detected
as a Node.js application even if it is a PHP application, then you
need to manually set your application to use this buildpack:
$ heroku buildpacks:set heroku/php
This will use the officially published version. To use the default
branch from GitHub instead:
$ heroku buildpacks:set https://github.com/heroku/heroku-buildpack-php
Please refer to Dev Center for further usage instructions.

Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings.>
Should i specify some path in settings or may be i'm using incompatible versions? (i'm using Django==2.0.2)
From Heroku's docs, add the following to your settings.py:
import dj_database_url
DATABASES['default'] = dj_database_url.config()
DATABASES['default']['ENGINE'] = 'django.contrib.gis.db.backends.postgis'
GDAL_LIBRARY_PATH = os.getenv('GDAL_LIBRARY_PATH')
GEOS_LIBRARY_PATH = os.getenv('GEOS_LIBRARY_PATH')
Here is the correct Heroku Documentation on how to include gdal in your Heroku app. In brief, in your Django App root:
1. Create an empty file called Aptfile
2. In that file, include the line `gdal-bin` and save
Then:
$ git add Aptfile
$ git commit -m "Add apt dependency"
$ git push heroku master
This should have gdal running and accessible on your dyno.

Push your project to Heroku again, it will work now.
The issue was in the curl-http2 buildpack: the version it was trying to download no longer exists on Ubuntu's servers. I have resolved this just now.
Should you run into a similar problem in the future, and it's not a build error in your application code, please open an issue at the GitHub repo of the failing buildpack.
I am using this "Heroku buildpack for Dart" from the following Github repository: https://github.com/igrigorik/heroku-buildpack-dartam .
I followed the set of commands to deploy the HTTP server built with Dart to Heroku and once I try to push the app to Heroku (git push heroku master) I receive the following error:

remote: this file is not a zipfile, or it constitutes one disk of

Any advice is much appreciated! Thanks in advance.
