Way to fix ImageMagick on Mac?

I keep getting the following error message from trying to use imagemagick:

julia> Pkg.build("ImageMagick")
INFO: Building Homebrew
Already up-to-date.
INFO: Building FFTW
INFO: Building SpecialFunctions
INFO: Building ImageMagick
Error: Your Xcode (1) is too outdated.

Xcode can be updated from the App Store.

=============================[ ERROR: ImageMagick ]=============================

LoadError: failed process: Process(`/Users/dan/.julia/v0.6/Homebrew/deps/usr/bin/brew install --ignore-dependencies xz`, ProcessExited(1)) [1]

================================[ BUILD ERRORS ]================================

WARNING: ImageMagick had build errors.

 - packages with build errors remain installed in /Users/dan/.julia/v0.6
 - build the package(s) and all dependencies with `Pkg.build("ImageMagick")`
 - build a single package by running its `deps/build.jl` script


Anyone have any luck solving it before?

edit: i have the newest command line tools. deleting xcode 9.2 isn’t explained anywhere on the internet… :confused:

For what it’s worth, I’ve just installed ImageMagick with julia 1.0.1 on a fresh Mojave setup with the following steps and no errors:

  1. brew install imagemagick (outside of julia)
  2. ] add ImageMagick and ] build ImageMagick with
(v1.0) pkg> add ImageMagick
