hadrian/ghci.sh doesn't work if ghci isn't on PATH
hadrian/ghci.sh
requires ghci
to be on your PATH
. This is a regression from the old utils/ghc-in-ghci/run.sh
method.
"But how could you ever get this far and not have ghci
on your PATH
?" you might ask? This is actually quite a common circumstance if you use stack
as your main build tool, where stack repl
s the command to load ghci
.
