Updating asset store post processing stack for 2017.3

I’m stuck using Unity 2017.3 for a class project, and was wondering if anyone had successfully updated the scripts in the official post processing stack available from the asset store. Some fail to compile in more recent versions of Unity. I tried downloading the WIP version available on GitHub, but it seems to have compile errors as well.

Download the release of Post Processing Stack 2 in github.

Hmm. I’m back to getting compile errors with it:

Severity Code Description Project File Line Suppression State
Error CS0433 The type ‘PostProcessEffectSettings’ exists in both ‘Assembly-CSharp, Version=, Culture=neutral, PublicKeyToken=null’ and ‘com.unity.postprocessing.Runtime, Version=, Culture=neutral, PublicKeyToken=null’ Stem.Editor G:\Stem Unity\Current\Stem\Assets\PostProcessing\Editor\Utils\EditorUtilities.cs 275 Active

There are 46 errors along those lines.
