4 years ago Looks like you're pretty new to Haskell and need some help with using cabal?
I'm not very familiar with cabal documentation that is targeted at beginners. Maybe you could start with this: https://cabal.readthedocs.io/en/3.4/getting-started.html#creating-a-new-application
This issue tracker is not a very good place for these questions though. https://www.reddit.com/r/haskellquestions/ would probably be better place.

cabal?I'm no expert but I'm not pretty new to Haskell. It turns out I needed to delete my .cabal directory. I deleted it then downloaded a cabal 3.2 binary, moved it to a newly, created empty ./cabal/bin, did a cabal update, reinstalled ghc 8.10.1, then did a cabal v1-install unordered-containers. This solved my issue.
I wasn't having any problems with other packages so filed a bug about the issue I was having. After filing it I thought about trying the preceding.
Since I was able to figure it out on my own I didn't look at the following.
