#4806: Make error message more user friendly when module is not found because package is unusable -------------------------------------+------------------------------------- Reporter: mitar | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.0.1 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by sgillespie): Agreed; however, GHC does display the same contradictory message with hidden packages: {{{ Prelude> :m + Data.Map <no location info>: error: Could not find module ‘Data.Map’ It is a member of the hidden package ‘containers-0.5.11.0’. You can run ‘:set -package containers’ to expose it. (Note: this unloads all the modules in the current scope.) }}} I think it would make sense to use the same language for both scenarios. I can either update both, or leave them both the same. What do you think? In the meantime, I'm going to go ahead and submit a review so someone can start reviewing it -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/4806#comment:28> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
