PHP composer報錯certificate verify failed的解決方案

環境: centos7

使用 composer 安裝依賴的時候報錯了. 出現了如下的錯誤描述:

Failed to download laravel/laravel from dist: The "https://files.phpcomposer.com/files/laravel/laravel/48f44440f7713d3267af2969ed84297455f3787e.zip" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failedFailed to enable cryptofailed to open stream: operation failed

是認證出現了一些問題.

嘗試修複:

yum update -y

待全部軟體更新後, 重啟機器, 再次嘗試composer 來安裝依賴, 成功了
