Could not find module ‘Control.Exception.Safe’

(newbie to Haskell here)

When I try to compile using "stack build" the compilation fails with the same error it's currently failing in the travis pipeline:
https://travis-ci.com/github/parsonsmatt/servant-persistent

When running with "make ghcid-devel", it runs just fine.

I'm using ghci 8.6.5 and stack 2.5.1.

Ps. great example! I'm learning a lot with it. Thanks.

Same issue here; I was able to fix it by adding 'safe-exceptions' to the build-depends part of the library stanza in servant-persistent.cabal. A related error then came up with the 'say' package; that too was fixed by adding 'say' to the library build-depends.
