Symfony6 + php8 = composer ffmpeg 安装依赖问题

Question

I am trying to install composer require php-ffmpeg/php-ffmpeg but I get dependency error:

  Problem 1
    - Root composer.json requires php-ffmpeg/php-ffmpeg ^0.18.0 -> satisfiable by php-ffmpeg/php-ffmpeg[v0.18.0].
    - php-ffmpeg/php-ffmpeg v0.18.0 requires doctrine/cache ^1.0 -> found doctrine/cache[v1.0, ..., 1.12.1] but the package is fixed to 2.1.1 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

I don't understand how doctrine cache could be conflicting? I tried -W but I get even more errors... ??

Could a composer guru help?

my composer.json:

Looks like someone has opened a PR to fix this in the repo, but it hasn't been updated since March. In the meantime, there is a workaround , if you trust using a forked repo created by some random user:

"require": {
  "php-ffmpeg/php-ffmpeg": "dev-psr"
},
"repositories": [
    {
        "type": "vcs",
        "url": "https://github.com/ekyna/PHP-FFMpeg.git"
    }
],
