Installing laravel suddenly some json file cannot be downloaded

Question

I typed create-project laravel/laravel "foldername" and got this message:

[Composer\Downloader\TransportException] The "http://packagist.org/p/illuminate/console%241d2f57f687204b9a57e5848fe9f49e79bc2fb7ed0cafc6d1387ad4760a1b155c.json" file could not be downloaded (HTTP/1.1 404 Not Found)

What's this for? I already got the laravel structure files but i don't want to continue without knowing whats with this error.

Update: composer.json content under my laravel folder structure

    ]
},
"config": {

add this on your composer:

"repositories": [
    {
         "type": "composer", 
         "url": "https://packagist.org"
    },
    { "packagist": false }
]

and run composer update once again. If not then run composer self-update

composer:update command not found when i run composer self-update, "You are already using composer version 1.6.2 (stable channel)." – Vlael Jan 15 '18 at 14:16

What does this do? Removing packagist from the sources and adding it again looks fishy.... – Nico Haase Jan 15 '18 at 14:31
in which file do you add this ? – DevonDahon Nov 22 '19 at 16:35

This worked for me on Linux. It prioritized ipv4 over ipv6.

sudo sh -c "echo 'precedence ::ffff:0:0/96 100' >> /etc/gai.conf"

But why? Can you explain why this is necessary? – Xanlantos Jan 02 '21 at 12:14
I can't "explain" it, but it seems packagist has problems with IPv6 https://github.com/composer/composer/issues/4142 – LeTigre May 21 '21 at 07:58

You need php curl module for this to work properly.

Check if you have php-curl with php -m

if Curl is not present on the list, install it with (debian) apt install php***-curl replacing *** with your php version

apt install php7.4-curl works for debian with php 7.4 installed.

Try again after installing the curl php module and voilá
