Question

我已经在ubuntu 16.04.4上上传了我的laravel 5.6项目。当我在上面上传我的工作项目（API在邮递员上经过测试）时，它返回一个空白响应，并在url上显示“此页面无效”“ HTTP ERROR 500”。

据我了解，我项目的php版本与服务器上的版本不同。

我的项目基于php 7.1.9构建，服务器php版本为7.1.18

任何形式的帮助或信息都是有用的。预先谢谢你

Answer 1

此错误是因为您的php服务器版本可能与执行php -v时看到的版本不同。

检查此问题的正确方法是在服务器端而不是CLI上执行php信息。

如果您需要在apache上启用php 7.2，这是ubuntu上的命令

首先禁用旧的php版本

sudo a2dismod php7.0

启用新版本

sudo a2enmod php7.2

local.ERROR：语法错误，意外的'？'，期望变量（T_VARIABLE）
