Hi,
To help we need to know more information about your version of OroCRM. Please try with follow instructions http://oroinc.com/orocrm/doc/current/cookbook/how-to-install-extension-from-command-line#using-composer

Composer will show errors or any incompatibilities

I tried to install package through console php app/console oro:package:available –env=prod but I had got this error:
oro/crm-zendesk can’t be installed!
And that’s all. I have reinstalled orocrm couple times, last time it was two weeks ago. Please, give me advise, how I can catch this? :)

P.S. My oro-crm version is 1.7.5 (7b00e38)
oro-platform is 1.7.5 (dfab0eb)
Thank you.

Hello, ant-workaholic
try install using composer with this command
composer require oro/crm-zendesk:1.4.0 --prefer-dist --update-no-dev
and after that run

php app/console oro:platform:update --env=prod --force php app/console cache:clear --env=prod

1 2	php app/console oro:platform:update --env=prod --force php app/console cache:clear --env=prod

About this command
app/console oro:package:available –env=prod
it only shows list of available extensions
the installation command should this

app/console oro:package:install oro/crm-zendesk

1 2	app/console oro:package:install oro/crm-zendesk
