These are the errors I got, I do not know is it in my images. Before, I saved my images inside my cover folder, then I rename my cover folder to covers, still not working into heroku push

Answer 1

Try

RAILS_ENV=production rake assets:precompile

and push to heroku.

Check your app in production env locally.

Answer 2

Git does not check what you push but Heroku does. There seems to be an error in you assets. Usually it is a mistake in the CSS files. Check on which line the error is and correct it. Than push again to git and than try again to push to Heroku. When your app is coded correctly there should be no problem with pushing to Heroku. Check your assets or post the full error log here so we can see where the error is in your assets.

In your case it is a problem with a JS file.

ExecJS::RuntimeError: SyntaxError: Unexpected token: operator (<) (line: 14589, col: 0, pos: 440984)
at new JS_Parse_Error

following the output from Heroku you should be able to figure out where the problem is. OR just try to push without that javascript file. This will at least guarantee a successful push and you can edit the JS file later.

TIP: check the Heroku logs after

rake aborted!

EDIT: The standard bootstrap javascript file in downloaded version should work. May be you edited something? It's unconventional but you can for deploying purposes just delete the .js file extension. For example .js__ and Heroku will not treat it as a JS file. Problem solved. No need to delete all files from the folder. If you do not like that solution you should take out the // require *tree from your application.js or take out all uncorrect JS files from your rails app.

The javascript folder can stay. The problem is the wrong JAVASCRIPT in the Javascript Files. Please find the wrong file and prohibit it from being precompiled as mentioned above. If you only have bootstrap.js file than change the file extension or delete it from your app. The error for deployment should be solved like that.
