php - 语法错误，Laravel 更新后出现意外的 ')'

问题描述

我已将我的 laravel 项目"laravel/framework": "^8.12"从 laravel 5.7 更新，但在我运行更新后composer dump-autoload它返回此错误

Generating optimized autoload files> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover --ansi

In TestDatabases.php line 148:

  syntax error, unexpected ')'

这是我的composer.json

如何解决这个错误？

解决方案

您需要将 PHP 安装升级到至少 7.3 版才能解决此问题。

PHP 7.2自 2020 年 11 月 30 日起EOL（生命周期结束）！

正如评论中已经指出的：

Laravel 8 需要 php 7.3 或更高版本

Larvel 8 在中具有以下 PHP 版本约束composer.json：

"require": {
  "php": "^7.3|^8.0"
}

除非您有（非常罕见的）正当理由，否则不要使用该标志运行。composer--ignore-platform-reqs
