We get an error if the Project Name has “spaces” or even and underscore “_”. For now the workaround can be

Do not use spaces or special characters like “_”

Additional Notes: IntelliJ IDEA 2020.2 Haskell 8.6.3 OS MacOS 10.15.6 Plugin version 1.0.0-beta78

@rikvdkleij I tested it, and stack new <packagename> works on the command line.

However, a bit more experimenting showed what the actual problem is. I was just getting started with a book on Haskell, and was trying to create a project/package called “Chapter-01”. Which stack new on the command line explains is an invalid package name, leading to it not creating the project, and the subsequent missing Cabal file.

Perhaps a check on the project/package name would be helpful for people new to Haskell.
