Unable to install on PHP 8.2.1? about prophecy-phpunit

[stof]

The issue is that you use PHPUnit 10, which is not supported yet. Work for that is in progress (but I won't manage to complete it before my vacation week that starts tomorrow so you'll need to wait a but).
Stick to PHPUnit 9.x for now.

Why is it trying to install phpspec/prophecy v1.15.0? There's v1.16.0, which is compatible to PHP 8.2.

What was the exact command you used?
Does it help to add -W (--update-with-all-dependencies)

If that doesn't help, what does composer why phpspec/prophecy say?

Problem 1
- phpspec/prophecy-phpunit v2.0.0 requires php ^7.3 -> your php version (8.1.12) does not satisfy that requirement.
- phpspec/prophecy-phpunit v2.0.1 requires phpunit/phpunit ^9.1 -> found phpunit/phpunit[9.1.0, ..., 9.6.4] but it conflicts with your root composer.json require (^10.0).
- Root composer.json requires phpspec/prophecy-phpunit ^2.0 -> satisfiable by phpspec/prophecy-phpunit[v2.0.0, v2.0.1].

Similar problem here with PHP 8.1

Any update on this?

[davidrans]

Looks like PHPUnit 10 support has been added on master. Any chance we could get a new release soon?

[TheLevti]

Master is broken as well as it requires a version of phpspec/prophecy that does not exist yet. Had to fork it out and fix master and then use dev-master until maintainer does a proper release.

@TheLevti you don't need to require dev-master. prophecy has a branch alias so its dev-master version fulfills the existing requirement.
However, when you want to use the dev version, you indeed have to allow composer to use the dev version of prophecy.
