Workaround for using composer

[yazzou]

I am struggling to unable simple AMP module on a drupal site hosted on Octopus platform for 2 days now :(. I am trying to follow the installation instructions :
http://cgit.drupalcode.org/amp/tree/README.md?h=7.x-1.x

and i am stuck at the point :

If you don't see any dependencies download, try drush composer-json-rebuild followed by drush composer-manager install when in docroot

I do have the following error :

octopususer.ftp:[www.mysite.com]$ drush composer-manager install
Download and install the Drush Composer extension? (y/n): y
Directory /home/octopususer.ftp/.drush exists, but is not writable. Please check directory permissions.                                 [error]

Here is what i have on drupal admin

I understand that it is due to security reason
as mentionned here : #677

Can you please provide a workaround to allow me to install AMP module ? I have thought of manually creating composer directory and download the files into it
I am not sure that it is the way to do it and i do not want to break anything on the plateform.

Ok i have finally the solution. I went to /files/composer and taped "composer update"
Thanks for taking time to read and sorry for any inconvenience

Can you remind how to get to the single site /files/composer from the terminal?

I was trying to install SendGrid_integration module and I couldn't cause of composer-manager dependency.

@kopeboy

To display drupal root: drush @foo.com dd

Or, to go to the site's directory directly: cd ~/clients/yourclient/sitename

Please note that BOA forces this:

$conf['composer_manager_vendor_dir'] = 'sites/' . $_SERVER['SERVER_NAME'] . '/vendor';
// Support for composer_manager

[kopeboy]

Yeah I was stupidly placing a / before platforms/xxx/xxxxxx/sites/mysite/files/composer

Apparently I could fix composer-manager just by running composer update once there like yazzou said.
It installed the required libraries (components?) for the Sendgrid_integration module.

...And, I have no idea what
$conf['composer_manager_vendor_dir'] = 'sites/' . $_SERVER['SERVER_NAME'] . '/vendor'; // Support for composer_manager
implies, and what should I do about it?
