OK, I am trying to install haskell again using the instructions given in this guide.

I removed my existing stack installation and my .stack directory, installed stack again, created a new stack project and then ran the recommended command in the guide to install ghc-mod and related tools: "stack build -j 8 --copy-compiler-tool ghc-mod hoogle weeder".

I get an error:

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for ghc-mod-5.8.0.0: Cabal-2.0.1.1 from stack configuration does not match >=1.18 && <1.25 (latest matching version is 1.24.2.0)

...etc.

Can someone explain what's causing this?
