Haddock "could not find links for"

I tried to use haddock to generate documentation for the library and while it is running it will not bind any types that are part of the GHC / standard libraries and emits this error:

Warning: The documentation for the following packages are not installed. No
links will be generated to these packages: array-0.4.0.1, base-4.6.0.1,
binary-0.5.1.1, rts-1.0, bytestring-0.10.0.2, containers-0.5.0.0,
deepseq-1.3.0.1, ghc-prim-0.3.0.0, integer-gmp-0.5.0.0, utf8-string-1
Haddock coverage:
  93% ( 14 / 15) in 'projectname'
Warning: SHA1: could not find link destinations for:
    GHC.Base.String Data.ByteString.Lazy.Internal.ByteString GHC.Word.Word32 GHC.Integer.Type.Integer GHC.Types.Int Data.Sequence.Seq

      

        
        
        
      

    

Now I googled around and found that the solution would try to reinstall these packages with haddock install array-0.4.0.1 base-4.6.0.1 binary-0.5.1.1 rts-1.0 bytestring-0.10.0.2 containers-0.5.0.0 deepseq-1.3.0.1 ghc-prim-0.3.0.0 integer-gmp-0.5.0.0 utf8-string-1 --enable-documentation

, but with error

cabal: Could not resolve dependencies:

==4.6.0.1)

and also doesn't even find a package called rts. What's happening?
