How to properly import an extension through Composer?

Question

Apache HTTP Server

Hello!

Recently started working with Composer. I want to import an extension (eg Twig) for a project, I enter a command, but it gives an error..

e:\programmer\php\tutorials\composer\vkdeepmine-master>php composer.phar require
 twig/twig:~1.8
Could not open input file: composer.phar

If you run from the folder of Composer itself, then ok, but it imports not in the project itself, but in the program folder

C:\ProgramData\ComposerSetup\bin>php composer.phar require twig/twig:~1.8
./composer.json has been created
Loading composer repositories with package information
Updating dependencies (including require-dev)

  - Installing symfony/polyfill-ctype (v1.18.1): Downloading (100%)
  - Installing twig/twig (v1.43.1): Downloading (100%)
Writing lock file
Generating autoload files

1) How can I make this command work in the project folder?
2) If not, can I simply copy the downloaded packages to the project folder?

Thank you.

Installing Composer globally and running is simple: composer require ...
