我在实时服务器上使用 Laravel 登录 API 时出错

Question

I am getting an error using laravel api, the error only appears when I have uploaded my project on live server, but it is working on live server

syntax error, unexpected 'Parser' (T_STRING), expecting function (T_FUNCTION) or const (T_CONST)

Controller for API:

<?php

namespace App\Http\Controllers\API;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\User; 
// use Illuminate\Support\Facades\Auth; 
use Validator;
use Auth;

    class UserController extends Controller
    {
        public $successStatus = 200;
        /** 
         * login api 
         * 
         * @return \Illuminate\Http\Response 
         */ 
        public function login(){ 
            if(Auth::attempt(['email' => request('email'), 'password' => request('password')])){ 
                $user = Auth::user(); 
                $success['token'] =  $user->createToken('MyApp')-> accessToken; 
                return response()->json(['success' => $success], $this-> successStatus); 
            } 
            else{ 
                return response()->json(['error'=>'Unauthorised'], 401); 
            } 
        }
    }

The error is in this file,

ParseError: syntax error, unexpected 'Parser' (T_STRING), expecting function (T_FUNCTION) or const (T_CONST) in file /home/.../.../.../project/vendor/lcobucci/jwt/src/Configuration.php on line 22

I have solved the issue by updating php version from 7.3 to 7.4, although in package.json the require version is 7.2.5
