Library UnityEngine.Animations.Rigging doesn't exist

Good evening everyone

I just imported the rigging package in Unity (2020.3.26f1 on MacOS) and ... I got this (see uploaded screenshots):

It says the namespace doesn't exist, I thought I typed it wrong but ... nope, it should be like that, how am I supposed to solve it ?

Cheers

 

help? I literally cannot work because of this bug
I tried restarting my computer and Unity already

 

Hello,try pressing the "import" button in "Animation rigging" and restart visual studio.
It helped me

 

Issue got solved by itself without me doing anything
Super weird ... nothing I did helped ..

 

Same on Unity 2021.3.12f1 with Animation Rigging package 1.1.1

 

From my previous experience, you can only wait and hope it solves by itself, as it is what happened for me ..

 

I had a similar issue with my VSCode not recognizing UnityEngine.Animations.Rigging. I tried many things (deleting .csproj, regenerating project files, reimporting packages, updating VSCode, creating Assembly Definitions, etc).

Finally I came across this thread, which pointed out that there was a specific bug with csproj files in the VSCode package version 1.2.4. So I updated my Unity package for Visual Studio Code Editor to version 1.2.5, unchecked all boxes and regenerated project files as described in that thread, and it finally worked. Just leaving here for future reference.

 

Same issue here, any news?

 

Just go to "Edit/ Preferences/ External Tool" and click "Regenerate project files"
it's work for me .
