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) vendorpsrlogsrcLoggerInterface.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 CLI php-v
Here my composer.json

Delete the vendor folder, delete the composer.lock file, then run composer install. that worked for me
I added this in the composer.json and it worked.
The run.
composer update
This downgraded psr/log to a lower version from 2.0 and resolved my issue.
This character ‘|’ is used only in php version >= 8.0
You can update the php version
That worked for me 🙂

I also faced this error when I upgrade ubuntu version from 20 to 22. I was using php 7.4 version. I tried to find the solution on google and mostly was saying to upgrade php version to 8. I updated to php 8 version but then again composer start throwing errors in Laravel project. Nothing helpful. So I uninstall php 8 and then reinstall composer and php 7.4. Everything start working fine. So in my conclusion. We can try these steps:
I got the solution.
uninstall composer using following command
switch to compatible php you are looking for using following command (if multiple php versions are running on your system)
then install composer using older method given on below link
https://getcomposer.org/download/
This can be caused by using the wrong actual PHP version with the PHP-version stated in composer.
If the other solutions not does works, u can try this:
