I opened a Haskell file on a fresh installation of Emacs & Intero. While booting up, intero is trying to install an isolated GHC. This even though my project has stack.yaml which has system-ghc: true. Running stack install in this directory does not reinstall GHC.

Is there any way to make Intero use system ghc instead of reinstalling?

The emacs mode is probably trying to install the intero binary outside the context of your project, to ensure that the intero binary isn't affected by the project's library choices. I'm guessing that setting system-ghc: true in your user config file (~/.stack/config.yaml) instead will solve this problem.

You may also want to set install-ghc: false to disable automatic GHC installation.
