Dependencies of Third Party Libraries In Magento 2

Question

Recently I installed Mpdf library using composer in my Magento 2.1.7 local setup, and It is working perfect on localhost. Now I have to move those libraries to live server (I can not install there through composer as I don't have permission.) for that I have moved mpdf directory from magentoRoot/vendor/mpdf at same path on live, but it is not working on live server and throwing below error

Uncaught Error: Class 'Mpdf\Mpdf' not found

After moving files I have ran setup:upgrade and content:deploy commands. What I am missing here? Is there any other changes needed along with moving the library files?

Answer 1

Did you check vendor/composer/autoload_psr4.php? Magento 2 need to recognize your library through autoload.
