Download firebase SDK, the Unity project has problems

[akira32]

I download firebase sdk and mechahamster-master.zip and import them to Unity . But Unity appears some errors as below:

Same exact issue here, can't get this project running at all.

Are you running the correct Unity version?

The LeaderboardController script is missing from the prefab. Also wasn't sure about the missing Firebase.Leaderboard namespace. Turns out they're here ...
https://github.com/FirebaseExtended/unity-solutions/tree/master/Firebase_Leaderboard
I copied the script content over to get passed those issues but now have problems with missing Unity.Tasks. I had to remove that included dll because of a conflicted with a default Unity package (I'm trying to open it in Unity 2021 but this project references Unity 2017 which probably wasn't an issue back then).

"Library\PackageCache\[email protected]\Runtime\Core\IUnityServices.cs(11,9): error CS0433: The type 'Task' exists in both 'Unity.Tasks, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' and 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'"
