cabal: Failed to build haskell-code-explorer-0.1.0.0 (which is required by
exe:haskell-code-indexer from haskell-code-explorer-0.1.0.0).
alexwl commented 5 years ago

I've added cabal.project.freeze (for ghc-8.4.4): https://github.com/alexwl/haskell-code-explorer/commit/b5a3048a880c8ce1c2bfa795a39576d02f416be2.

cabal new-build all command builds everything correctly (cabal new-build doesn't build cabal-helper-wrapper executable which leads to a runtime error from haskell-code-indexer).
