I tried, but I got this error:

I remember trying with GHC 7.8.4 too, and AFAIR that also failed similarly.

Misc

I've used a new & empty cabal sandbox

cabal-install version 1.22.2.0

Looks like your happy executable needs to be upgraded. You can install the new version with cabal-install. Alternatively, using stack will automatically install the correct version of happy.

  • Indeed, putting happy-1.19.5 into my path (was 1.18.9) allowed me to install haskell-src-meta. Thanks! – Wizek Jul 17 '15 at 10:28
