Composer install shows error on Server. Working fine on local machine.

[yan]

I am facing this when I run composer install on my server.
Everything is working fine on local.

Server is Ubuntu 16.04.6 LTS, PHP 7.3.
Bagisto version is v0.1.6(28th of June, 2019)

There are many changes I have already made so I would rather not upgrade bagisto to latest version. So it will be great if there is any solution to fix this.

Hi @yan

Can you attach your composer.json file ?
