Hi all! I'm trying to use ghc-mod with my Yesod-project, but I get this error: $ ghc-mod ghc-mod: <command line>: cannot satisfy -package-id yesod-static-1.4.0.4-c893310d859222b1b20461f9fdb4d916 (use -v for more information) My project builds correctly. In my .cabal-file I see this dependency: build-depends: base >= 4 && < 5 , yesod >= 1.4.0 && < 1.5 , yesod-core >= 1.4.0 && < 1.5 , yesod-auth >= 1.4.0 && < 1.5 , yesod-static >= 1.4.0 && < 1.5 ... I use LTS-2.18, and I see this package in ~/.stack/snapshots/x86_64-osx/lts-2.18/7.8.4/lib/x86_64-osx-ghc-7.8.4/: ... yesod-static-1.4.0.4 ... So, what can I do? Please help me. Sincerely, Denis.
