I get an error message when i try to push my heroku app. I have a runtime.txt with the text python-3.7.10, i have a requirements.txt, i have a Procfile and im not really sure what's missing. python 3.7.10 is a supported runtime. Can anyone help me, im really stuck. It keeps saying "Requested runtime (Python-3.7.10) is not available for this stack (heroku-20)". Thanks in advance!

Heroku-20 is the default stack for newly created apps: within this stack you can use different languages and versions.
In case of Python the supported versions are:
python-3.9.7
python-3.8.12
python-3.7.12
python-3.6.15
You runtime.txt sets Python-3.7.10 which is not supported: correct the version or remove the file (relying on the default version python-3.9.7).
I really need some help with what seems to be the most basic task (setting up the expo/react-native project). I've installed the expo-cli (v3.11.7), react-native (v2.0.1), watchman (v4.9.0) and node (v12.14.1). I've followed the tutorial up until the point where I need to run expo start and I get the following error:
Your project is in SDK version >= 33.0.0, but the expo package version seems to be older.
Error: node_modules directory is missing. Please run npm install in your project directory.
Couldn't start project. Please fix the errors and restart the project.
Set EXPO_DEBUG=true in your env to view the stack trace.
I've then run npm install and tried again but the same error pops up. I've removed the node_modules folder and that didn't work either.
Update:
When I npm install this is the error I'm seeing:
npm WARN deprecated core-js#1.2.7: core-js#<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js#3.

I've installed yarn (v1.21.1) and tried installing using this with the same error:

Can anyone advise?
I've managed to solve the problem. I was trying to install over my home network, which apparently has some proxy restrictions! No idea why.
Someone advised me to try again but connected to another network or my mobile hotspot. I tried this and it worked! Problem solved. So I guess for any others that may be experiencing the same problem, try connecting to another network and see if that helps.
If this fails, then I suppose looking at the proxy configuration and making changes there may help. But I wouldn't advise doing this unless you know exactly what you're doing.
When using absolute paths in my CRA, the build step fails on heroku.
NODE_PATH=src/
Is in my .env.local file and also use this env var in my heroku settings.
I try to build my app on heroku using the "heroku-postbuild" script (which just runs "react-scripts build". I am using an express server to serve this build folder and to proxy requests to various API's.
this is the error I get:
remote: Running heroku-postbuild (yarn) remote: yarn run
v1.14.0 remote: $ react-scripts build remote: Creating
an optimized production build... remote: Failed to compile.
remote: remote: ./src/app/App.js remote: Cannot find

remote: remote: You can install this package by running: yarn
add checklist/Checklist. remote: remote: remote: error Command failed
with exit code 1.
the Checklist.js file is located under: "src/checklist/Checklist.js"
Any idea what I need to do to make this work?
I had this issue and it seemed to be a result of my local file having a different casing than the one committed to git. i.e. if you have a file Checklist.js committed to git and are trying to import checklist from 'checlist/checklist.js', run git mv [...]/checklist.js [...]/Checklist.js.
See this issue comment for the original answer that got me here.
Just create a jsconfig.json file on the root of your project and paste this(if you use src as the starting point for your absolute imports
{
"compilerOptions": {
"baseUrl": "./src"
}
}

How can I get my application pushed to Heroku?
Make sure you are pushing a repo that contains a proper supported app ( Rails, Django etc.) and you are not just pushing some random repo to test it out.
Newbie in Heroku: Error when push my app to Heroku
If that is not the case and you are pushing what you think is a valid app, contact Heroku support and they will fix it for you.
Make sure that you are using either npm or yarn.lock file-
Two different lockfiles found: package-lock.json and yarn.lock
Both npm and yarn have created lockfiles for this application,
but only one can be used to install dependencies.
After deleting yarn.lock and pushing the code again to git, my issue resolved.
Deleting package-lock.json solved it for me
First, disable collectstatic:
heroku config:set DISABLE_COLLECTSTATIC=1
Then run:
git push heroku master
For more details and full steps, check here.
I faced the same problem:
! [remote rejected] vX.X.XX -> master (pre-receive hook declined)
error: failed to push some refs to 'git#heroku.com:[application-name]'
I realized that my heroku application Stack is 'cedar-10' and was deprecated from 04/11/2014 and disabled from 04/11/2015 (Cedar-14 is now Generally Available).
The solution was to upgrade the heroku application Stack following the guide:
Upgrading the production app to Cedar-14
Another issue could be that in a production environment, you can't use sqlite3, the default database when you make a rails app.
In order to fix this, just change the database your rails app uses to Postgres. This can easily be accomplished by editing your Gemfile
From your Gemfile, remove:
gem sqlite3;
and add the following:
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'pg'
end
I had the same problem but with a Django app, it turned out that pip wasn't able to download/install one of the dependencies of the requirements.txt file (it was eyeD3)
A little late to the game, one of my issues was I had an outdated sshkey. Just need to update that in the settings.
Another thing was I was pushing Python Django CMS, and it was running python manage.py collectstatic during deploy and it was failing. So make sure you check the log heroku logs --tail. That gave me another hint to turn off collectstatic, it event tells you what to type to turn it off.
Came across this same error when deploying a node app, but resolved with these two steps and thought I'd share in case anyone else runs into the same issues.
Make sure you aren't committing node_modules since heroku installs dependencies from package.json on push. Try adding node_modules/ to your .gitignore to ensure you don't accidentally commit it
Heroku uses Node v12 which node-sass 4.10.0 will fail to build with. Try increasing node-sass version by adding the following. This allowed it to build successfully for me:
"devDependencies": {
"node-sass": "^4.12.0"
}
In case if this needs anyone in future even though I am a beginner and doesn't know much about Heroku, you may have requested a version in runtime.txt file which the stack doesn't support.
python-3.8.2 to python-3.8.10
Changing from python-3.8.2 to python-3.8.10 helped me solved it. You may see the supported stacks here: https://devcenter.heroku.com/articles/python-support
I had this problem (same error with Heroku):
To https://git.heroku.com/myapp.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/myapp.git'
The mistake
I made some changes to my code and removed some parameters, apparently I missed a simple comma (,) on a line. This caused a build error. Which was not visible in the console upon pushing, only the "pre-receive hook declined" error.
SOLUTION
I fixed the comma issue, rebuild and pushed to Heroku and now it works.
If you have an error in your css this error can also show up.
In one of my media queries I put
#media screen adn (min-width: 1000px) {
Instead of the "and" which gave me this error.
A good indicator that this may be the case is if you get an error that contains the message
"Tasks: TOP => assets:precompile ... Precompiling assets failed"
That was my first clue to look in my css.
I decided to read the logs line by line.
Below is part of the error logs:
remote: > gbt-ltd-website-frontend#0.1.0 build /tmp/build_c37edf59
remote: > react-scripts build

remote:
To https://git.heroku.com/gbtstructurals.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/gbtstructurals.git'
From where the error started, "npm ERR! code ELIFECYCLE" I read up and I found the actual cause of the error. It was a CSS rule. I first removed the rule and it built. Then I checked my declarations and found out I was contradicting myself.
i thought , this will not be the error occured due to any app , or code changes.
i have same problem now this happen due to the following reason:
1) i have code on bitbucket/git i push the code to repository (this
repo is linked with the heroku app,meanse changes to this will
reflects on heroku)
2)after pushing code to repo , i am trying to push code on heroku
with "git push heroku master" but due to some reason i abort this
command, thats why code is not pushed to heroku
3)then i am agian triyng to push code to heroku it says same error
as above
4) the solution for this is "just pull yours last commited code"
and push the changes to heroku ..thats it thanks
I had this with a sinatra application. (Heroku does support Sinatra).
The instructions on the heroku blog post were incomplete
https://blog.heroku.com/32_deploy_merb_sinatra_or_any_rack_app_to_heroku
My program ran fine locally but I got that error when trying to push to heroku.
The heroku blogpost didn't include the need to make a gemfile and do bundle install. The program was running locally fine, but to make it work on heroku it needed a Gemfile and bundle install on it.
this link here https://teamtreehouse.com/community/how-can-i-make-my-sinatra-app-public mentioned that I needed a Gemfile, and mentioned the contents of the Gemfile. And then to do bundle install. Then once that is done, then follow the instructions on that heroku blog post, of making the program file, and the config.ru and the git repo and doing heroku create (which also creates the remote), then git push heroku master.
i.e.
Gemfile as mentioned at treehouse link
# define our source to look for gems
source "http://rubygems.org/"
# declare the sinatra dependency
gem "sinatra"
And bundle install to install that Gemfile.
bundle install
hello.rb (as mentioned on heroku blogpost)
require 'rubygems'
require 'sinatra'
get '/' do
"Hello from Sinatra on Heroku!"
end
config.ru
require './hello'

For me it was an unused import in java app , removed the unused import and everything built fine.
In my case I had an npm script called "build" that had the as value npm run build --prefix client.
Heroku automatically executes the npm run build command and it couldn't build my React app. Probably because Heroku didn't install react-scripts module.
So I renamed the command to build-client and now I can push the changes to Heroku.
Checking you config vars (in heroku) may be a good idea.
I had the same error message, when I created a pipeline for my app and wanted to push to the newly created staging app. It didn't work because the config vars I had previously set were not transferred to the new staging app (obviously). After I added the variables once more, pushing to heroku git worked flawlessly again.
I had a similar issue with a recent application after running:
git push heroku master
The error:
remote: ! Push failed
remote: Verifying deploy...
remote:
remote: ! Push rejected to stormy-escarpment-13653.
remote:
To https://git.heroku.com/stormy-escarpment-13653.git
! [remote rejected] master -> master (pre-receive hook declined)
The problem was that I was in the wrong directory when I ran the command. I needed to be in the root of the application.
So I ran a git rm --cached <app_name>, to clean up and the ran again and it worked as expected.
My issue was I forgot to bundle install before pushing.
The steps which work for me
1: I just remove package-lock.json and yarn.lock
2: user npm install command
3: then push the changes to the github
4: use "git push heroku main" command.

My issue is that there was one file which I did not add in my previous git commit. The problem was fixed after I added that last file, and pushed another commit.
When I checked the logs, it showed this error:
remote: -----> Build
remote: Running build
remote:
remote: > student-app-frontend#0.1.0 build
remote: > react-scripts build
remote:
remote: Creating an optimized production build...

remote:
remote: ^
remote:
remote:
remote:
remote: -----> Build failed
This shows that Heroku was not able to find the imported file 'designUtils/fontDesign.js'
This is because I used the command git commit -am 'latest changes' instead of using the commands git add., then git status to check if everything was added properly, and then git commit -m 'latest changes'
For me it solved by this command:
git push heroku master --force
or
git push heroku your_branch_name:master --force
Try Updating Node/php or any engines to latest version and then deploy again it will work for sure.
you need to mention the language in the root directory
