Ovh and composer

Question

I have a site that I just put on OVH hosting shared pro and I try to update Drupal 8 but I encounter several problems:

-If I try to update through the interface I can not update because I have a message related to the PHP bug 2038

I'm trying to use composer.

I have some questions :

• Should I install directly composer on my FTP host or on the www folder?

• When I try the command php composer.phar update drupal / core I get the message "Composer could not find a composer.json file in home / my_id"

• When I try in the www directory, I have the message "Drupal / core package for update is not installed. Loading dials repositories with package information Updating dependencies (including require-dev) Nothing to install or update Generating autoload files Drupal \ Core \ Composer \ :: Composer preAutoloadDump Drupal \ Core \ Composer \ :: Composer ensureHtaccess "

For information I have well the composer.json file in my www directory.

Could you help me to start please. Thank you

You shouldn't run Composer on your production environment. Definitely use it to build your site but push a complete build artefact to production (including all the vendor folders and such).

Also the command is composer update drupal/core (no spaces).
