New project creation failing with intero build errors

aberent commented 5 years ago

Here is what should have been in the description:

I create a new, empty, project with a project SDK of Haskell Stack Tool (1.9.3), and I get lots of error messages about problems with intero. See below.

Once this happens I don't get the Haskell Error window, or error checking in the editor window.

12/05/19 19:35 Executing /usr/local/bin/stack build intero failed: /usr/local/bin/stack build intero:
Error: While constructing the build plan, the following exceptions were encountered: In the dependencies for intero-0.1.39: ghc-8.6.5 from stack configuration does not match >=7.8 && <=8.6.4 (latest matching version is 8.6.4) needed since intero is a build target. Some different approaches to resolving this:

Set 'allow-newer: true' in /home/anthony/.stack/config.yaml to ignore all version constraints and build anyway.
Consider trying 'stack solver', which uses the cabal-install solver to attempt to find some working build configuration. This can be convenient when dealing with many complicated constraint errors, but results may be unpredictable.
Recommended action: try adding the following to your extra-deps in /home/anthony/haskell/htest/stack.yaml: ghc-8.6.4@sha256:628bc341218b5631136e015bdc6d2cf73f7888304554a1caaf659881672402fe Plan construction... (show balloon)

Now that I have investigated a bit more, it turns out that there is an easy workaround; change the resolver version in stack.yaml to lts-13.19 or earlier.
