Can't install dependency error

[nomadme]

Composer is having trouble installing the package.

Seems like it is caused by the symfony/css-selector

./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Well, Goutte 4.0 requires symfony/css-selector 4.4+. And your project currently contains symfony/css-selector 4.3.8. So that's indeed not compatible. There is 2 possible fixes for that:

• allow composer to update the symfony/css-selector dependency (composer require has a --update-with-dependencies option to include dependencies in the partial update, and --update-with-all-dependencies which does the same even if they are root dependencies). By default, composer require forbids any update of package already present in the lock file
• use an older version of fabpot/goutte compatible with Symfony 4.3

The solution to choose depends on your project.
