Error installing haskelly to use with VSCode

I'm trying to install Haskelly so that I can use VSCode to build and debug Haskell. The issue here is that when I try to install intero, Quick Check and stack-run using the following command:

stack install intero QuickCheck stack-run

I get the following error:

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for stack-run-0.1.1.4: conduit-1.3.1.1 from stack configuration does not match >1.1 && <1.3 (latest matching version is 1.2.13.1) conduit-extra-1.3.4 from stack configuration does not match >=1.1 && <1.2 (latest matching version is 1.1.17) needed since stack-run is a build target.

Some different approaches to resolving this:

  • Set 'allow-newer: true' in C:\sr\config.yaml to ignore all version constraints and build anyway.

  • Recommended action: try adding the following to your extra-deps in C:\sr\global-project\stack.yaml:

    • conduit-1.2.13.1@sha256:afd4db7fe66ae7af3d418e1a932384a8dee08df2f6299cca80e53ba964ce1228,4371
    • conduit-extra-1.1.17@sha256:dfa0d00dc11a8a4c3fdff15374c378ee34c25a2255b52194aa1ea3c1f1a63fd7,4521

Plan construction failed.

Now while it does provide some clues as to what I'm supposed to do, I have no clue what it means to add these things to stack.yaml. I found stack.yaml, and it's just a file that I seemingly can't open or modify. Does anyone know how I can fix this issue?

This is a problem installing stack-run, documented here: https://github.com/yamadapc/stack-run/issues/21.

I solved it by adding the following to my stack.yaml:
