Does not build

When I do "stack build", I get the following errors:

directory must match >=1.2 && <1.4, but this GHC boot package has been pruned (issue
          #4510); you need to add the package explicitly to extra-deps  (latest
          matching version is 1.3.4.0)
process must match >=1.1.0.2 && <1.7, but this GHC boot package has been pruned
        (issue #4510); you need to add the package explicitly to extra-deps  (latest
        matching version is 1.6.7.0)

Hi Kevin, thank you for reporting this issue. Could you please try to upgrade your stack distribution via stack upgrade or in other way depending on how you've installed it? Does the problem still persist?

I did stack upgrade shortly before doing stack build.

mac> stack --version
Version 2.3.3, Git revision cb44d51bed48b723a5deb08c3348c0b3ccfc437e x86_64 hpack-0.33.0

Unfortunately, I can't reproduce this behavior. Could you please add the following lines in the end of the stack.yaml file:

  - directory-1.3.3.0
  - process-1.6.5.0

Does this change fix build for you?

Thanks, @alexander-myltsev. Fixed.
