Can't run Composer -- directories and files owned by "web"

Questions & Answers
#1

I’ve got a trial Professional account. In an SSH session, I want to add a module to a Drupal site using Composer:

 composer require drupal/admin_toolbar

But in the /app directory, the host shows directories and files are owned by “web” so composer.json isn’t writable (and caches can’t be created).

Before I chown everything in /web, is there a Platform.sh way to handle this?

Hi @linkletter - would you mind pasting in a copy of your .platform.app.yaml file?

Hey @linkletter - I don’t see anything in your build hook, which is the only time the file system is writable.

I’d try either running composer require drupal/admin_toolbar first locally and pushing the updated composer.lock file, or placing that line in your build hook.
