I've always installed extensions by default by putting all files in the directory.
I found a PDF generator which must be installed by composer.
I have opened the SSH console in the magento root directory and try to run first command:
composer config repositories.magento2-pdf-generator2 git firstname.lastname@example.org:EaDesgin/magento2-pdf-generator2.git
Unfortunately, get error:
- command not found
Can anyone help me how can I install this module by composer?
