[Haskell-cafe] problems with stack, config.yaml

A year ago I tried to install stack on my MacBook. Just recently I tried
again, and it asked me if I wanted to upgrade rather than install. I did
so, but got an error (some message from GHC saying 'the thing that should
never happen, happened' or something like that). So I thought, okay let me
try uninstalling stack first, then installing it, and going from there.

So I did that, and I'm working the stack tutorial, and upon doing "stack
setup" I got a parse error in config.yaml.

   "Error in $.params: failed to parse field 'params', expected Map k a,
encountered String"

As far as the question of where I got my config.yaml from, I edited
something that was there to add some specific information, but I am not
sure if I changed anything else. Here is the config.yaml that produces the
above error:

# This file contains default non-project-specific settings for 'stack', used
# in all projects.  For more information about stack's configuration, see
# http://docs.haskellstack.org/en/stable/yaml_configuration/

# The following parameters are used by "stack new" to automatically fill
# in the cabal config. We recommend uncommenting them and filling them out
# you intend to use 'stack new'.
# See https://docs.haskellstack.org/en/stable/yaml_configuration/#templates
