Why is PHP Curl Class not being installed?

Question

ubuntu

I install curl class
In the console I type as indicated in the documentation:

composer require php-curl-class/php-curl-class @dev

Result:

I don't see any errors. Next, I read the documentation, you need to connect the file require __DIR__ . '/vendor/autoload.php';
Which is missing during the check ................ WHAT DID I DO WRONG, did it install? something tells me that no ..
ps And another additional question: Does everyone install it all through one place? I won’t hide one place already on fire ... any installation always causes a bunch of errors and problems - is it to take into account 2019?)

Answer 1

1. don't run composer as root.
2. composer require must either be called in the root directory of the project (judging by the screenshot, you run it in a hamster), or set globally.
