I'm using php version 7.4 but I'm always getting the following item:

syntax error, unexpected '|', expecting variable (T_VARIABLE)

I am running command "php artisan serve --port9091" and in console.log it is showing that I am using php7.4 version as below:

Laravel development server started: http://127.0.0.1:9091
Cannot load Xdebug - it was already loaded

If you notice it is saying the error I mentioned above, I've already seen that this is referring to the PHP version, but as I said and in the text above I'm using the 7.4 version, what have I done?

• deleted vendor folder
• composer install
• composer update

And the error persists.

My composer version is 2.4.3

For a better example I'm putting my composer.json below as well.

CodePudding user response：

I believe this is because of your php version. update your composer.josn and type the correct php version.

"config": {
        "platform": {
            "php": "your php version"
         }
   }

and run composer update or composer install.

CodePudding user response：

it may cause many other things this error will occur.

For laravel, delete the vendor folder, and the composer.lock file and then run composer install. it worked for me
