As I understand this error mean that some of my packages are not ready for php 8. What can I do to update packages which are ready?
I tried to update composer.json for the prooph components
"require": {
"php": "^7.1",
"prooph/common" : "^4.0.0"
}
to
"require": {
"php": "^7.1 || ^8.0",
"prooph/common" : "^4.0.0"
}
and run command composer.phar update --lock --with-all-dependencies but it's not help
When I tried to update vimeo/psalm by "composer.phar update vimeo/psalm 4.4" I got the same error. Does it mean that prooph require old version of psalm and it not allow to update it?
How to resolve this problem and update all which are ready?

Answer 1

Pretty simple, the following two lines tell it all:
prooph/service-bus is locked to version v6.2.2 and an update of this package was not requested.
prooph/service-bus v6.2.2 requires php ^7.1 -> your php version (8.0.1-dev) does not satisfy that requirement.
According to that package's information, there is no version compatible with PHP 8. And as written in a blog post by one of the maintainers, there will be no new versions of this package.
Updating the other packages should be possible by updating your composer.json. As you haven't shared the current state of your configuration, it's not possible to tell you what you need to change, but the most simplest way is taking one line after the other, check for updates on packagist.org, and adjust the version constraint. But be warned that it's pretty likely that you run some major upgrades. Having a good test suite helps to check which upgrades cause which problems
