Permission denied when migrating in DigitalOcean

Question

I'm using the DigitalOcean terminal to try run a Phinx migration vendor/bin/phinx migrate -e development but I get the error "permission denied"

I have tried writing the command in different ways, I have made sure the data in my phinx.php is correct.

I'm really stuck, anyone have any experience with this?

Full Command:

root@webportal-project-name:/home/project/project-name# vendor/bin/phinx migrate -e development

Error:

-bash: vendor/bin/phinx: Permission denied

Phinx.php:

<?php

return

    'paths' => [
        'migrations' => '%%PHINX_CONFIG_DIR%%/db/migrations',
        'seeds' => '%%PHINX_CONFIG_DIR%%/db/seeds'
