Installation fails via installer

[clarktr1]

Hi!
I have a Blacklight instance in production and public facing after some tinkering. It is older with Blacklight 8.3 and its compatible version dependencies. I am now trying to automate redeployment. However, every time I go through either installer I always run into one of two issues. This is when trying to install Blacklight >= 8.0

1. Manifest.js is missing. This was something I had to copy into the upper level directory when overriding files. But, it did exist prior. Does the Blacklight installer not create this manually?

2. When I don't receive the first error, the follow up is that Blacklight can't find @import blacklight-marc, despite also using the installers. This works when it is commented out, but, I'm sure it's included for a reason.

Following the quick start guide should just get me to a point of the vanilla app, right?
