I have a Symfony v5.x project.
I want to install it on my Windows PC.
I copied the project folder to wamp/www.
I execute the command composer install.
It throws the following error:
curl error 6 while downloading https://flex.symfony.com/versions.json: Couldn't resolve host name
I found the solution here. The proposed solution is to execute the command:
composer update symfony/flex --no-plugins --no-scripts
It now throws another error:
laminas/laminas-code 4.3.0 requires php ^7.4 || ~8.0.0 -> your php version (7.3.5) does not satisfy that requirement.
- symfony/proxy-manager-bridge v5.3.0 requires friendsofphp/proxy-manager-lts ^1.0.2 -> satisfiable by friendsofphp/proxy-manager-lts[v1.0.5].
- friendsofphp/proxy-manager-lts v1.0.5 requires laminas/laminas-code ~3.4.1|^4.0 -> satisfiable by laminas/laminas-code[4.3.0].
- symfony/proxy-manager-bridge is locked to version v5.3.0 and an update of this package was not requested
I found a possible solution which proposes to modify composer.json as follows:
"require": {
"php": "^7.3|^8.0",
}
If I run:
composer dump-autoload
composer update symfony/flex \
--no-plugins \
--no-scripts
... I still get the following error:
- laminas/laminas-code 4.3.0 requires php ^7.4 || ~8.0.0 -> your php version (7.3.5) does not satisfy that requirement` stays.
This is my composer.json:
