[FIXED] How do I install maatwebsite/excel?

Issue

I'm trying to install maatwebsite/excel; however, I can't get it to work.

I tried deleting the composer.lock file and running:

composer install
composer update

I also tried:

composer require maatwebsite/excel --update-with-dependencies

Neither method worked.

The error I received was:

To enable extensions, verify that they are enabled in your .ini files:
- C:\Users\user\Downloads\php-7.3.8-nts-Win32-VC15-x64\php.ini
You can also run `php --ini` inside terminal to see which files are used 
by PHP in CLI mode.

Installation failed, reverting ./composer.json to its original content.

Solution

In my stuation, the error happened because composer wasn't able to load the phpoffice/phpspreadsheet package. Normally, composer is capable of installing dependencies. However, there were some missing php extension on the server – like php zip. Once I installed those extensions, the problem was solved.

Instead of ignoring requirements, I suggest you to look into the source of the problem.
