Installation procedure: table notification doesn't exist

[ywarnier]

There's a new issue in the installation process, at step php bin/console doctrine:migrations:migrate :

[notice] Migrating up to DoctrineMigrations\Version20210701135912
[error] Migration DoctrineMigrations\Version20210625154452 failed during Execution. Error: "An exception occurred while executing 'ALTER TABLE notification CHANGE is_read is_read TINYINT(1) DEFAULT '0' NOT NULL':

Importing silk.sql before php bin/console doctrine:migrations:migrate fixes the issue, but then the next step fails:

php bin/console doctrine:fixtures:load --append

  There are no commands defined in the "doctrine:fixtures" namespace.                                                                                                                  

  Did you mean one of these?

  You may be looking for a command provided by the "DoctrineFixturesBundle" which is currently not installed. Try running "composer require doctrine/doctrine-fixtures-bundle --dev".  

Installing doctrine/doctrine-fixtures-bundle as suggested doesn't fix the issue.

Without the fixtures installed but with the yarn commands executed, I get redirected to a /login URL which is "Not Found". It sounds to me like there are some .htaccess missing or instructions to provide in the vhost, or some URL management rows in the database (through fixtures?)

The new installation procedure works as documented in README.md, except for the DoctrineFixturesBundle step reported above (which still happens). Working on it...

The README has been updated with the --env dev argument and the installation now works fine, thanks to @TonyHaikara
