Not finding System.Random #220

Closed AndrewC19 closed 3 years ago

AndrewC19 commented 6 years ago

When using the IDE-Haskell, if I use an import such as import System.Random, I get an error:

Failed to load interface for `System.Random' Use -v to see a list of the files searched for.

However, if load the module directly in ghci it works as expected.

Any ideas why?

So, any luck?

AndrewC19 commented 6 years ago

In the end no, reverting back to ghc 8.0.2 seemed to cause other issues. Just have to stack exec atom for now!

Okay. Just be aware that building with cabal will likely fail -- cabal will complain about GHC_PACKAGE_PATH.

Any advice on fixing this?

lierdakil commented 5 years ago

@dmotz, the most common reason for this is a missing package in the cabalfile build-depends.
