Heroku 部署：'composer install' 过程因错误而失败

Question

I try to deploy my project to Heroku using the following command:

git push heroku master

Although it was working fine before now it gives me these errors:

remote:  !     WARNING: There was a class not found error in your code
remote:

here is composer.json file:

        "post-create-project-cmd": [
            "@php artisan key:generate --ansi"
        ]
    }
}

I have tried all the instructions and implemented these commands in terminal:

composer update git add composer.json composer.lock

I do know where is the error from because I have tried many solutions even deleting what`s inside post-create-project-cmd.

If anyone could help me with this I would appreciate it

Answer 1

I have encountered this issue. Try removing all files on the heroku bash

Steps

1. heroku run bash
2. ~$: rm -rf.*
3. ~$: rm -rf *

Reclone (force)

4. git push heroku master -f

If It says its updated, then you can just clone normally ~$: heroku git:clone -a <insert app name>

Answer 2

just run heroku restart

your heroku bash get stuck and the server need to restart
