Hi,
I've followed the instruction exactly but I get:
» docker-compose exec php composer run-script install:with-mysql
> scripts/install-mysql.sh
./scripts/install.sh: line 23: /var/www/vendor/drush/drush/drush
: No such file or directory
ERROR Drush is required to install Contenta CMS. Please install Contenta CMS using Composer. See http://www.contentacms.org/#install
Script scripts/install-mysql.sh handling the install:with-mysql event returned with error code 5
Drush is installed correctly in the vendor directory and the path to it in the script seem ok.

Someone has an idea ?
