Hi folks! I haven't used Yesod quite a while; now when I'm trying to run development server of freshly scaffolded PostgreSQL stack's template I see this error message: Rebuilding application... (using cabal) Starting development server... *<command line>: cannot satisfy -package-key main* (use -v for more information) Exit code: ExitFailure 1 I've found several issues on the web, however I wasn't able to resolve this. I've tried to upgrade my Yesod binary first via `stack install yesod-bin`. Now I have: stack exec yesod version *yesod-bin version: 1.4.18.7* stack --version *Version 1.1.2 x86_64 hpack-0.14.0* I also tried to comment out the test suite section in cabal file, but devel server still fails to run. Can someone clarify how to deal with this?
