Can't build for Oculus Go - Unity library missing

[daveinpublic]

EDIT: Solved! Replied below.

Can’t build for Oculus Go because when I start building, this dialogue box pops up right away:

Unable to package apk
Mono library missing for the selected architecture 'armeabi-v7a (/Applications/Unity/Hub/Editor/2018.4.14f1/PlaybackEngines/AndroidPlayer/Variations/mono/Release/MonoLibs/armeabi-v7a/libmono.so) !

My software should be up to date, I just downloaded the latest Unity LTS and Oculus packages, details here if needed.

Current Setup
Unity 2018.4.14 (the latest Unity LTS).
Package manager: Latest Oculus packages (Oculus Desktop 1.38.4 and Oculus Android 1.38.6).
Latest Oculus Utilities Plugin or OVR Plugin (1.26).

When I start up Unity 2018 LTS with this project, I always get these errors in the console as soon as Unity opens:

Plugins: Couldn’t open Assets/Oculus/VR/Plugins/1.26.0/OSXUniversal/OVRPlugin.bundle/Contents/MacOS/OVRPlugin, error: dlopen(Assets/Oculus/VR/Plugins/1.26.0/OSXUniversal/OVRPlugin.bundle/Contents/MacOS/OVRPlugin, 2): Library not loaded: @rpath/LibOVRRT_0.framework/Versions/5/LibOVRRT_0

I’m taking a project that I began in Unity 2018.2, and am just building for Oculus Go… it used to work in 2018.2. When I start the build, I get the ‘Unable to package app’ dialogue box and these error messages in the console:

Figured out the issue!

It was just a bad install. It hadn’t downloaded the Android module, and didn’t allow me to add any modules to it. I uninstalled and reinstalled, and then I got the ability to add the Android module.
