"No Cabal file info" error while creating new Haskell project or module

See original GitHub issue

Hello! I get a “No Cabal file info. Could not create Haskell module because could not retrieve or parse Cabal file for package path None” when trying to create a new Haskell project or module using the plugin.

macOS 10.12.6, IntelliJ CE 2017.2.2, IntelliJ-Haskell 1.0.0-beta11 Haskell Platform 8.0.2 installed via homebrew

Stacktrace from IntelliJ:

Indeed it was a problem with my Stack configuration: I was missing the template params in the ~/.stack/config.yaml.

Thank you for helping me identify the issue. Do you think the IntelliJ-Haskell plugin could do with a more user friendly error message for such a case? Otherwise feel free to reject the ticket.

Can you try on the command line: stack new --bare hspec

This command is executed by plugin when creating new project.
