Type the following at the command line: xcode-select --install
and then try ghci again. I'm not sure what you mean by "the software" in the phrase "Should I delete and reinstall the software you told me to install?" but in any case don't delete anything. Please try to be as specific as possible. When you first encounter a problem you should Google for a solution. If that doesn't work you can send mail to me but also cc ghc-d...@haskell.org and glasgow-haskell-users@haskell.org Cheers George On Thu, Mar 16, 2023 at 11:09 PM William McEnaney < bill.mcenaney...@gmail.com> wrote: > Hi, George, > > Sorry to bother you.
