tymon/jwt-auth is preventing the installation of lcobucci/jwt (https://github.com/tymondesigns/jwt-auth/releases/tag/1.0.2), unfortunately, this is a conflict that can't be resolved right now, unless you're willing to install an older release of the SDK.

The newest release you can use is 5.11.0, so I think if you first do a composer require "kreait/firebase-php:<5.12.0", it should work.

I've written <5.12.0 instead of 5.11.0 because I think it shows more clearly that it's an old version, at least for me, so that I'm constantly reminded to check if there's a new tymon/jwt-auth release 😅.

The actual solution would be if tymon/jwt-auth would be updated (it currently can't be used with PHP 8 as well), there are a couple of requests for that in https://github.com/tymondesigns/jwt-auth/issues already. 🤞

not using jwt-auth, but facing same issue when install laravel-firebase.
jmespath/jmespath.php failed

sanctum related?

[jeromegamez]

jmespath.php has no dependencies that I can see that could conflict with lcobucci/jwt, could you share some details on what "failed"?

i try open another fresh copy of laravel 8.
i am not sure about this, but this keep coming up when install.

found the problem related to jwt 3.3.3

solution as below,
try to lock your firebase-tokens: <1.12.0
try to lock your firebase-php:<5.12.0

it should be installable along laravel passport.
