Having looked in the docs for build pack I can't seem to see anything that helps me. Any help would be appreciated.
Please follow all steps from Heroku documentation.

I am trying to deploy my tweetbot to Heroku but thins have refused to be pushed because of this error below;

My files are very small so I don't know where the 617M size is coming from
What is the way forward? Thank you.

It would be very nice if anyone could help me with this, or even recommending an other way to deploy django projects for free
That entire traceback is inside these parentheses: () is not available for this stack. That is the message shown when you request a Python runtime that isn't available. In this case, it looks like your runtime.txt can't even be read due to an unexpected encoding.
Delete it, then create a new file containing something like
python-3.10.2
only. Make sure it is UTF-8 encoded, commit, and redeploy.
At the moment, these are the currently supported Python versions, but the list changes as new versions are released:
python-3.10.2
python-3.9.10
python-3.8.12
python-3.7.12
I had the same issue when i was deploying my django application to Heroku. The issue is because of encoding error. Heroku is expecting the file to be saved with utf-8 but I realised that my file was saved with utf-16 le.
So if you are working in vscode then i would suggest to check the encoding for the runtime file at the bottom of vscode
If you click on utf-8 you will get the option of saving the file with different encoding .
Otherwise you can also save the file in notepad. Default encoding used by notepad is utf-8 only
That will work for sure.
Check for other files encoding also if this doesn't solve the problem
very simple
just delete the runtime.txt and push the code
this worked for me .
thankyou
I am trying to deploy a Flask app to Heroku and I keep getting this error. Anyone who can help me with this?

Based on the UPDATED question, the error message is hinting at the problem:
No default language could be detected for this app.
You need to tell Heroku what kind of app you are deploying. For Python apps (i.e. Flask), you need to have one of the following files in your top-level git directory, as described in the Expected files for Python section of Deploying Python and Django Apps on Heroku docs:
Heroku automatically identifies your app as a Python app if any of the
following files are present in its root directory:
requirements.txt
setup.py
Pipfile
If none of these files is present in your app’s root directory, the
Python buildpack will fail to identify your application correctly.
Take note of the the warning at the end that if none of the files are present, the Python buildpack will faill.
The simplest here is to add a requirements.txt file. You can generate this by doing:
pip freeze > requirements.txt
and it looks like this:
Flask==1.0.2
Flask-Scss==0.5
gunicorn==19.7.1
isort==4.3.3
itsdangerous==0.24
Jinja2==2.10.1
...
Add that to the top-level of your git directory.
Then, for Flask, you need to add a couple more files:
runtime.txt
This specifies the Python version of your app, as described in Specifying a Python Runtime
python-3.7.3
Procfile
This is described in this post Heroku Flask Tutorial Procfile Meaning and I suggest you take a look. The contents depends on how you instantiated your Flask app instance, and it looks like this:
web: gunicorn app:app --log-file=-
If you're still having problems, I highly recommend going through the Heroku tutorial docs, especially Getting Started on Heroku with Python.
If I go to the the build log I see the following:
-----> Node.js app detected
FATAL: ROOT_URL is not defined.
! Push rejected, failed to compile Node.js app.
! Push failed
This is what I am getting in my terminal:
remote: Building source:

remote: FATAL: ROOT_URL is not defined.
remote: ! Push rejected, failed to compile Node.js app.

NOTE: I do not know what to do to fix this and get my app working, I have checked multiple discussions on people having a somewhat similar problem but I was not able to fix it with their solutions.
I don't know much about Meteor so I'm not sure why this works in development, nor can I find any canonical list of critical settings that are required for it to work. The closest I can find is the documentation for Meteor.absoluteUrl (bold added):
Generate an absolute URL pointing to the application. The server reads from the ROOT_URL environment variable to determine where it is running. This is taken care of automatically for apps deployed to Galaxy, but must be provided when using meteor build.
You should be able to get past this issue by setting the ROOT_URL variable on Heroku, e.g.
heroku config:set ROOT_URL=https://virtually-viral.herokuapp.com
or through the web interface.
I'm trying to follow the tutorial at https://mmcgrana.github.io/2012/09/getting-started-with-go-on-heroku. Initially everything seems to work:

And the app gives an error:
What am I doing wrong?
I tried a bunch of things that didn't work:
downgrade go version (to match the one defined in https://github.com/kr/go-heroku-example/blob/master/Godeps/Godeps.json)
move from default Eclipse Go structure to one without src, bin, or pkg inside project
use hyphens instead of underscores (for project name and in Procfile and Godeps.json)
define full identifier in Godeps.json
At the end and started from scratch again, creating the project from the command line instead of from Eclipse, and this worked.
From the things above, I can rule out #1 and #4 as fixes, as I'm back to using the same config I initially had.
Another thing that was throwing me off was references to ".godir" in different websites and posts. I don't know what this file used to be used for, but it doesn't seem necessary any more.
I'm going to point to Eclipse and its Go plugin as the culprits, for now.
Heroku now officially supports Go and has a Getting Started guide.
