Required dependencies not updating - php

Question

I'm updating some packages with composer. I'm using Laravel5.6 in my project.
The one that I'm trying is PHPStan to version 0.10.7. My current version is 0.9.2.
The problem
When I try to update, it shows a success message, but when checking the outdate packages output, it is still OUTDATED.
What I've tried
Using composer why-not phpstan/phpstan 0.10.7 gave me the following output:
laravel/laravel my-branch-test requires (for development) phpstan/phpstan (^0.9.2)
phpstan/phpstan 0.10.7 requires nikic/php-parser (^4.0.2)
laravel/laravel my-branch-test does not require nikic/php-parser (but v3.1.5 is installed)
phpstan/phpstan 0.10.7 requires phpstan/phpdoc-parser (^0.3)
laravel/laravel my-branch-test does not require phpstan/phpdoc-parser (but 0.2 is installed)
Then I tried to update nikic/php-parser and phpdoc-parser and re-run composer update phpstan/phpstan but it gave me the same result of before. (not updating)
UPDATE: running composer update phpstan/phpstan --with-dependencies gave me the following output:(but still didn't updated phpstan)
composer update phpstan/phpstan --with-dependencies
Do not run Composer as root/super user! See https://getcomposer.org/root for details

Package sebastian/git is abandoned, you should avoid using it. No replacement was suggested.

In my composer.json file, the package is listed as:
"require-dev": {
"phpstan/phpstan": "^0.9.2",
Any ideas?

The problem here was that others packages that I was using were using the nikic/php-parser package too, but considering only non-breaking changes (nikic/php-parser":"^3.0"), "blocking" the upgrade to > 4.0.
Because of composer can't install two versions of the same package, my solution was not updating phpstan for now.
I will wait for the libs that require nikic/php-parser to update their requirements to 4.0 and up or will change these packages in the future.
