Laravel 8 供应商/lcobucci/jwt/src/Configuration.php 错误

Question

syntax error, unexpected 'Parser' (T_STRING), expecting function (T_FUNCTION) or const (T_CONST)", "exception": "ParseError", vendor/lcobucci/jwt/src/Configuration.php", "line": 22

I have PHP 8.0 and composer v2.0 installed.

The project work locally using xampp perfectly but showing this error in Ubuntu 20.04, nginx config on Digtalocean

Answer 1

I had the same exact err, causing a 500 internal server error.

by adding "lcobucci/jwt": "^3.3.3" to my composer.json fixed the issue.

It's mostly dependencies issue, first I downgraded my laravel/passport from 10.1 to 10.0 in my composer.json and my laravel/framework from 8.22.1 to 8.21.0 as it was working fine at that point.

vm:~$ php -v
PHP 7.4.13 (cli) (built: Nov 28 2020 06:24:43) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.13, Copyright (c), by Zend Technologies

my composer.json now looks like this,

"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].
    - Can only install one of: lcobucci/jwt[4.1.x-dev, 3.3.3].
    - Installation request for lcobucci/jwt 3.3.3 -> satisfiable by lcobucci/jwt[3.3.3].
