[FIXED] fatal: reference is not a tree on composer install

Issue

Trying to install packages on composer.json using composer install on production and I get this error.

I've tried different solutions which I found from search which includes

• Clearing cache
• running composer update
• Delete vendor, clear cache and run composer install
• Delete vendor, clear cache and run composer update

And none worked.

However, I was able to run composer install successfully on local.

How do I fix this? Attached is my screen with the error.

Thank you.

Solution

Depending on your flavour of Linux and PHP version these may vary.

(sudo) yum install zip unzip php-zip

or
