Сбой операции SSL с кодом 1 | Самозаверяющий сертификат в цепочке сертификатов

Спецификация: Windows 10 | Wamp | PHP 7.1.9

Попытка установить Laravel 5.5, используя документацию, которую они предоставили онлайн.

Каждый раз, когда я запускаю " composer global require "laravel/installer"", я получаю следующее как вывод:

Loading composer repositories with package information Updating dependencies (including require-dev) Package operations: 70 installs, 0 updates, 0 removals - Installing vlucas/phpdotenv (v2.4.0): Downloading (failed) Downloading (failed) Downloading (failed) Failed to download vlucas/phpdotenv from dist: The "https://api.github.com/repos/vlucas/phpdotenv/zipball/3cc116adbe4b11be5ec557bf1d24dc5e3a21d18c" file could not be downloaded: SSL operation failed with code 1.

Я перепробовал многие решения, представленные в Интернете, и большинство из них говорит об этом:

Загрузите новый cacert.pem и добавьте его в «C: \ wamp \ bin \ php \ php7.1.9 \ extras \ ssl \», а затем обновите файл php.ini как:

curl.cainfo ="C:\wamp\bin\php\php7.1.9\extras\ssl\cacert.pem" openssl.cafile="C:\wamp\bin\php\php7.1.9\extras\ssl\cacert.pem" 

Любое решение для этого?
