Webpacker isn’t creating a manifest after upgrading to 6.0.0.pre.2 I think I should revert to 5.3.0
I had to do that too.
Pre 2 is a very very very old version of webpacker 6. The latest version is webpacker 6.0.0.beta.7.
The issue is due to rubygems.org (or maybe bundler) considering pre 2 “newer” I believe due to how the versions fall in alphabetical order.
