Файл "https://packagist.org/packages.json" не может быть загружен

Question

Я хочу установить пакет для приложения чата Laravel, которое я создаю.При запуске «composer require foo / bar» я получил следующую ошибку в терминале:

In RemoteFilesystem.php line 515:

The "https://packagist.org/packages.json" file could not be downloaded: failed to open stream: Unable to find the socket transport "proxy_user_name" - did you forget to enable it when you configured PHP?

Я использую VPN, но он все еще ссылается на мои учетные данные прокси, которые, как предполагается, не видны из-заVPN.

При запуске «Диагностика композитора» я получаю следующее:

Что может быть причиной ошибки?

Answer 1

Это связано с неправильной настройкой прокси.Попробуйте исправить свой прокси или отключить его (временно) с помощью

unset http_proxy;
unset https_proxy;

Вы можете использовать redsocks, когда вам нужно пройти через прокси.
