Parse error: syntax error, unexpected '|', expecting variable (T_VARIABLE) Symfony PHP VERSION WAMP Windows

Question

I have some syntax errors from symfony vendor when i'm trying to composer install my project.

Parse error: syntax error, unexpected '|', expecting variable (T_VARIABLE) vendor\psr\log\src\LoggerInterface.php on line 30

With several search, I saw the problem is from PHP version (have to be > 7.1), but actually my version is 7.4.9, this is a local machine, i'm working with WAMP on Windows. Symfony 4.4 version. Already tried to delete vendor, .lock...

Here the php version from phpinfo()

Here php version from wamp

Here php version from CLI php-v

Here my composer.json

Have some idea ?

Solution

I added this in the composer.json and it worked.

"config": {
        "platform": {
            "php": "7.4.21"
         }
   }

The run. composer update

This downgraded psr/log to a lower version from 2.0 and resolved my issue.

You seemingly have latest version installed, which uses PHP/8 syntax (you can check that with e.g. composer info psr/log). Either it's ignoring your "platform" settings for some reason, of you made changes but didn't update. Do you have a composer.lock file coming from the repository? Does composer update change something?

How does vendor\psr\log\src\LoggerInterface.php on line 30 look like, it is not accepting several parameters obviously, so there is a version issue with either the package or php.

[Álvaro González]

It's worth noting that the settings on the question already include a similar platform settings. It's possible that the OP didn't refresh with composer update or they had another issue.

Thx that saved my day. But note that you may have to re-install your libs (yust delete composer.lock and composer/installed.json and run composer update) to make this taking affect

This was it! I globally had PHP 7.4 (used by phpunit), but running in IntelliJ used the PHP 8.1 runner.
