doctrine/dbal not getting installed in Heroku

I am running a Laravel project on Heroku. For running a migration that will change the type of a column I need the doctrine/dbal package installed. I put "doctrine/dbal": "^2.5" line in composer.json in the "require" object.

When I pushed the changes to Heroku it is showing the line.

- Installing doctrine/dbal (v2.5.5)

Right after that when I ran heroku run composer show doctrine/dbal it is showing.

[InvalidArgumentException]
Package doctrine/dbal not found

I also ran heroku run composer update several times after that. Here is the full log of my commands.

Solution

  • So, the problem was that the composer.lock wasn't updated before I pushed the repo to Heroku.

    Heroku only runs composer install after a git push which reads the lock file to install packages. And as pointed out by Chris in the comments

    Don't bother running composer update on Heroku. Any changes you make to the local filesystem after your slug is compiled will be lost as soon as your Dyno cycles.

    So the best practice is, after editing composer.json in the local file system always run composer update and then git push.

    I moved "doctrine/dbal": "^2.5" from "require-dev" to "require" and didn't run composer update before pushing, that was the cause of the problem.
