php - SymfonyComponentDebugExceptionFatalErrorException laravel Error

Question

I am getting this error on my new Laravel project. I am trying to run after a fresh installation.

Declaration of SymfonyComponentTranslationTranslatorInterface::setLocale($locale) must be compatible with SymfonyContractsTranslationLocaleAwareInterface::setLocale(string $locale)

Answer 1

On my server following were configurations:

PHP 7.1.26-1+ubuntu14.04.1+deb.sury.org+1 Laravel Framework 5.7.28

Solution: Added "symfony/translation": "4.3.8" in composer.json as follows

"require": {
     ...
     "symfony/translation": "4.3.8",
}

and then

composer update

or (if php version is not recommended on the server)

composer update --ignore-platform-reqs
