创建 Laravel 项目时出现异常 "Your version of PHP... is affected by CVE-2013-6420..."

Question

在运行命令上：

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

我收到这些错误 -

Your version of PHP, 5.4.12, is affected by CVE-2013-6420 and cannot safely perform
certificate validation, we strongly suggest you upgrade.

任何人都可以告诉我可能是什么问题。我正在使用代理网络。在环境变量中我设置了 http_proxy & https_proxy.

Answer 1

对于 laravel 5.2 所需的 php 最低版本是 5.5.9 所以你必须升级你的 php 版本。此外，如果您使用代理网络，则只需要 http_proxy 作为系统变量，而不是 https_proxy 变量。
