Installing Composer to get local files of Magento - php

Question

I have a Debian VM with a Magento 2.1.7 Installed. Now, in order to get the files in local and being able with the IDE (I use phpStorm from JetBrains) to sync the files from local to remote with a Save I need to have the Magento files too in local.
The truth is that the only path I have in sync is:
/opt/bitnami/apps/Magento/htdocs/app
But anyway, having all the files and the vendor in local gives me the ability to have changes in local and not in the VM and I get organized better.
The problem comes when I want to install the Magento 2 files. I used to do computer install in other computers where everything was set up and all the dependencies got installed without any problem.
But in the machine I'm setting up now and I will work from now on I need to set it up.
Basically when I run composer install where I need to install the dependencies it says:
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.

To enable extensions, verify that they are enabled in your .ini files:
- C:\php.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
As far as I understand and I can read, I need a php.ini in the folder which tells the composer how to get the dependencies. I haven't found the file, i found two files:
php.ini-production
php.ini-development
I imagine these two files are the ones magento use once we change the mode, so, do I need to change these 2 eventually?
How can I fix this?

Answer 1

I managed to fix the problem by modifing the php.ini file that I had in C:\php.ini. I couldn't find it earlier but once found, just get rid of the comments on the sections you need.
