Failed to compile python (Permission denied!) while deploying some changes in heroku

Question

I have deployed a project of github in heroku. Then I successfully cloned the project with my pc using heroku slugs:download -a newocas

Now, after making some changes and doing commit while deploying the project back to heroku produces the same error again and again.

I'm using git bash for commit and deploy. Here's my error messages:

 Sultan@Sultan-PC MINGW32 ~/newocas/app (master) $ git push heroku master Counting objects: 133, done. Delta compression using up to 4 threads. Compressing objects: 100% (125/125), done.

and here's my requirement.txt file

Flask==0.10.1 future==0.16.0

I have tried this - Pip not found when deploying Django app to Heroku , this- Push rejected, failed to compile Python app , this- Heroku push rejected, failed to compile Python/django app (Python 2.7) and this - Heroku/python failed to detect set buildpack

But still the error occurs!!!

Could someone help me in this reagard

Answer 1

I have solved the problem. I'm sharing the procedure below:

Firstly, using heroku slugs:download -a newocas will not work in that case. When the app has been downloaded using slugs then it couldn't be linked to heroku afterwards.

So, the solution is to clone the app in the pc using git bash and then after any changes make a commit and then push the changes to heroku app.
