Installing psalm and phpunit 11 with composer

[thbley]

Currently it's not possible to install psalm and phpunit 11 with composer.

e.g. using composer.json

"require": {
        "phpunit/phpunit": "^11",
        "vimeo/psalm": "^5"
}

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - sebastian/diff[4.0.0, ..., 4.0.1] require php ^7.3 -> your php version (8.2; overridden via config.platform, actual: 8.2.15) does not satisfy that requirement.
    - vimeo/psalm[5.5.0, ..., 5.21.1] require sebastian/diff ^4.0 || ^5.0 -> satisfiable by sebastian/diff[4.0.0, ..., 4.0.5, 5.0.0, ..., 5.1.0].
    - vimeo/psalm[5.0.0, ..., 5.4.0] require sebastian/diff ^4.0 -> satisfiable by sebastian/diff[4.0.0, ..., 4.0.5].
    - You can only install one version of a package, so only one of these can be installed: sebastian/diff[4.0.0, ..., 4.0.5, 5.0.0, ..., 5.1.0, 6.0.0].
    - phpunit/phpunit[11.0.0, ..., 11.0.2] require sebastian/diff ^6.0 -> satisfiable by sebastian/diff[6.0.0].
    - Root composer.json requires phpunit/phpunit ^11 -> satisfiable by phpunit/phpunit[11.0.0, 11.0.1, 11.0.2].
    - Root composer.json requires vimeo/psalm ^5 -> satisfiable by vimeo/psalm[5.0.0, ..., 5.21.1].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Hey @thbley, can you reproduce the issue on https://psalm.dev? These will be used as phpunit tests when implementing the feature or fixing this bug.

Already fixed in #10639

Still seems a issue with the dev version of psalm.
But could the the 8.3 constrained?

  "require": {
  },
  "require-dev": {
    "vimeo/psalm": "5.x-dev",
    "phpunit/phpunit": "^11.0"
  },

  Problem 1
    - Root composer.json requires vimeo/psalm 5.x-dev -> satisfiable by vimeo/psalm[5.x-dev].
    - phpunit/php-code-coverage[11.0.0, ..., 11.0.x-dev] require nikic/php-parser ^5.0 -> satisfiable by nikic/php-parser[v5.0.0alpha1, ..., 5.0.x-dev].
    - You can only install one version of a package, so only one of these can be installed: nikic/php-parser[v4.16.0, ..., 4.x-dev, v5.0.0alpha1, ..., 5.0.x-dev].
    - phpunit/phpunit[11.0.0, ..., 11.1.x-dev] require phpunit/php-code-coverage ^11.0 -> satisfiable by phpunit/php-code-coverage[11.0.0, 11.0.x-dev].
    - vimeo/psalm 5.x-dev requires nikic/php-parser ^4.16 -> satisfiable by nikic/php-parser[v4.16.0, ..., 4.x-dev].
    - vimeo/psalm 5.x-dev conflicts with nikic/php-parser v4.17.0.
    - Root composer.json requires phpunit/phpunit ^11.0 -> satisfiable by phpunit/phpunit[11.0.0, ..., 11.1.x-dev].

Most likely we won't be supporting nikic/php-parser v5 in 5.x branch. master branch (future Psalm 6) already uses nikic/php-parser though.
