Error installing Entities package

Im trying to add Entities to a project, and I get this error after package is installed:

Assembly has reference to non-existent assembly 'Unity.PerformanceTesting' (Packages/com.unity.entities/Unity.Entities.PerformanceTests/Unity.Entities.PerformanceTests.asmdef)

I have tried installing all that I think is a required dep: Jobs, Mathematics, etc, but anyway, the error persists. How can I solve this?

 

You need to install the "Performance Testing API" in the Package Manager. Make sure to show preview packages.
Can't remember if it shows up by default or if you need to add this to your manifest first.
"com.unity.test-framework.performance": "0.1.50-preview"

 

I had this issue as well and had to manually remove the references.

 

For me, it appeared when I modified the manifest.

 

Getting this same error. Don't see the Performance testing package, plus the entire point of PakMan packages is that they can specify dependencies so why is this not properly listed as a dependency by the Entities package?

Seems like a bug to me.

 

To fix this until the Entities package has the proper dependency added, add the following to your project's manifest.json:

"com.unity.test-framework.performance": "0.1.50-preview"

 

Modifying the manifest.json (which is in the "Packages" folder of the project) in the way @jwvanderbeck described got it to work for me. Can't wait for this to be out of alpha so this nonsense can stop (No hate, Unity <3)

 

I added this dependecy and it shows in the Package Manager, but this do not work for me, is there any other dependecy needed?

 

Are you still getting the same error? If so then you didn't add it properly. If the error has changed, can you post the error?

 

I have fixed it. Besides "com.unity.test-framework.performance": "0.1.50-preview", I should add "com.unity.test-framework.performance" in "testables": [].
