"https://packagist.org/packages.json" file could not be downloaded: failed to open stream: Operation timed out

Question

This morning, I ran this command

composer create-project laravel/laravel laravel-4.2 4.2 --prefer-dist

I kept getting

The "https://packagist.org/packages.json" file could not be downloaded: failed to open stream: Operation timed out
Retrying with degraded mode, check https://getcomposer.org/doc/articles/troubleshooting.md#degraded-mode for more info

Anyone know how to avoid this ?

Answer 1

For me, this wasn't an issue with my internet connection speed, but it was a issue with IPv6 resolution of "repo.packagist.org". I got around this issue by adding the IPv4 address to my hosts file. It's a hack, but it works.

# dig +short repo.packagist.org
142.44.164.255
# echo "142.44.164.255 repo.packagist.org" >> /etc/hosts

Answer 2

try this solution worked for me!

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

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

I got the answer here and it works like voodoo...

Answer 3

For me it was ipv6, I disabled it using: networksetup -setv6off Wi-Fi on macOS. Worked like a charm.
