php - Inflector.php 第 265 行中的 FatalErrorException : syntax error, unexpected ':' expecting ';' or '{'

Question

我去更新 Composer 使用

composer update

更新后出现如下错误:

FatalErrorException in Inflector.php line 265: syntax error, unexpected ':', expecting ';' or '{'

请协助

提前致谢

使用 Laravel 框架版本 5.2.45

这是 Composer 的代码

        ]
    },
    "config": {
        "preferred-install": "dist"
    }
}

出现错误请看inflector.php函数

public static function tableize(string $word) : string
    {
        return strtolower(preg_replace('~(?<=\\w)([A-Z])~', '_$1', $word));
    }

Answer 1

这是一个 PHP 版本问题，更新到 PHP 7.0 和 doctrine/inflector 将正常工作，因为 doctrine/inflector 1.20 及以上版本需要 PHP 7。

但是如果您想保留当前的 ​​PHP 版本，可以通过运行以下命令来降级 doctrine/inflector 版本:

1. 删除composer.lock文件

   rm -f Composer.lock

2. 删除供应商

   rm -R -f 供应商

3. composer 安装

4. 根据你的 php 版本安装 doctrine/inflector

   composer 需要 doctrine/inflector:1.1.0

doctrine/inflector:1.1.0 支持 PHP 5.6 及更高版本。如果你有其他版本的php，可以引用this link
