php - 语法错误，Laravel 更新后意外 ')'

Question

我已将我的 Laravel 项目更新为 "laravel/framework": "^8.12"来自 laravel 5.7，但在我运行时更新后 composer dump-autoload它返回这个错误

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？

Answer 1

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 是 EOL (生命周期结束)自 2020 年 11 月 30 日起!
正如评论中已经指出的那样:

Laravel 8 requires php 7.3 or higher

Larvel 8 在 composer.json 中有以下 PHP 版本限制:

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

做 不是 运行 composer与 --ignore-platform-reqs除非您有(非常罕见的)正当理由这样做。
