语法错误，意外的 'Parser' (T_STRING)，期望函数 (T_FUNCTION) 或 const (T_CONST)", "exception": "ParseError", vendor/lcobucci/jwt/src/Configuration.php", “行”：22
我安装了 PHP 8.0 和 composer v2.0。
该项目在本地使用 xampp 完美运行，但在 Ubuntu 20.04 中显示此错误，Digitalocean 上的 nginx 配置
【问题讨论】：
我有同样的错误，导致 500 内部服务器错误。
通过将"lcobucci/jwt": "^3.3.3" 添加到我的composer.json 来解决此问题。
主要是依赖问题，首先我在composer.json 中将 laravel/passport 从 10.1 降级到 10.0
以及我的 laravel/framework 从 8.22.1 到 8.21.0，因为它当时工作正常。

我的composer.json 现在看起来像这样，
"laravel/framework": "^8.14",
"laravel/passport": "^10.1",
"lcobucci/jwt": "^3.3.3",
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Conclusion: don't install laravel/passport v10.1.0
- Installation request for laravel/passport ^10.1 -> satisfiable by laravel/passport[10.x-dev, v10.1.0].
- Conclusion: remove lcobucci/jwt 3.3.3
- laravel/passport 10.x-dev requires lcobucci/jwt ^3.4|^4.0 -> satisfiable by lcobucci/jwt[3.4.x-dev, 4.0.x-dev, 4.1.x-dev].
- Can only install one of: lcobucci/jwt[3.4.x-dev, 3.3.3].
- Can only install one of: lcobucci/jwt[4.0.x-dev, 3.3.3].

我做了composer install --no-plugins，它为我修复了错误。
