我在http://symfony.com/doc/current/deployment.html中做了所有事情 我做错了什么？

<小时/> 修改
我有7.1 php

Answer 1

我已经解决了在composer.json上设置php版本的相同问题：

"config": {
    "platform": {
        "php": "7.0.18"
    },
}

然后作曲家根据php版本更新包。

Answer 2

您使用的是PHP 7.0，但安装了ocramius/proxy-manager版本2.1.x，需要PHP 7.1。

看看这两个版本的差异：v2.0.x vs v2.1.x。

有两种解决方案：

• 将PHP升级到版本7.1
• 将ocramius / proxy-manager降级到版本2.0.x。
