PHP Fatal error: Interface 'PsrHttpMessageRequestInterface' not found | Laravel 5.6.4
I have a problem today I ran the "composer update" command in a project and it gave me this error in the error_log:
Interface 'Psr\Http\Message\RequestInterface' not found in /home/simbiothink/simbiothink/config/vendor/psr/http-message/src/ServerRequestInterface.php on line 43
