When running stack setup in Miso sample-app (https://github.com/dmjio/miso/tree/master/sample-app) following error occurred.

Shorter version:

    Just a guess: perhaps the `stack setup` code hasn't been tested with cabal-install 2.0 yet. You could try putting version 1.24 on your $PATH and see if things work then. – Michael Snoyman Jan 03 '18 at 18:33
  • @MichaelSnoyman Thanks for the advice. you mean stack-1.24 right! – Nagarjuna Pamu Jan 03 '18 at 18:35

    No, I meant cabal 1.24. I'm not familiar with the GHCJS code path, but it appears to use the `cabal` executable under the surface to do some of the work, and may be making assumptions about its version. (It's also very likely that it's the GHCJS scripts themselves making these assumptions.) – Michael Snoyman Jan 03 '18 at 18:36
  • @MichaelSnoyman Thanks, I will definitely try. `stack setup`, `stack build`, `stack clean` also fails with same error. – Nagarjuna Pamu Jan 03 '18 at 18:40

    @MichaelSnoyman Works after deleting `cabal-install` and running `stack build` – Nagarjuna Pamu Jan 03 '18 at 18:59

Works after deleting cabal-install and running stack build. As hinted by @MichaelSnoyman ghcjs might be expecting right cabal version.
