Composer.json Script, Returns 'event Returned With Error Code 2', Why?

- 1 answer

I was studying composer, and when creating this script, it returns 'event returned with error code 2', but it doesn't prevent execution, when I run it directly without composer it also works, and it doesn't give this error, I would like to know why this error occurs and how to resolve it. Thanks.

 //src

 <?php

    echo 'hello world';

 ?>

//composer.json
    "require-dev": {
        "phpunit/phpunit": "^9.5",
        "squizlabs/php_codesniffer": "^3.6",
        "phan/phan": "^5.3"
    },
    "scripts": {
        "cs" : "phpcs --standard=PSR12 src/"
    },


//running

PS D:\xamp\htdocs\fonts\ambiente\buscador-cursos-alura> composer cs

Answer

First Warning

End of line character is invalid; expected "\n" but found "\r\n"

Your line endings need to be LF and not CRLF, here's an article which explains the difference. If you're using VSCode then you can change the line ending in the bottom right where it uses CRLF by default. If you're not using VSCode then you will need to Google how to change the line endings for your IDE.

Second Warning

Expected 1 newline at end of file; 0 found

PSR12 coding standards require an empty line at the end of your PHP files.

Third Warning

A closing tag is not permitted at the end of a PHP file

PSR12 coding standards state that closing PHP tags at the end of the file should be omitted.

<?php
    echo 'hello world';
