Answer 1

I'm sure that you've solved this by now (at least hopefully! It's almost two months later!), but here's a solution that worked for me just now:

---

Uninstall imagemagick through homebrew:

• brew uninstall imagemagick

Clean your homebrew directory:

• brew cleanup --force -s
• --force removes all out of date keg-only brews, -s removes all cached downloads

Reinstall imagemagick:

• brew install imagemagick

---

After all of that, you should be good to go!

Answer 2

B. Ruschill's answer seemed to have solved many peoples' problem, unfortunately it didn't for me. Nor did many solutions I found on the internets.

Turns out I had an outdated version of libjpeg. I fixed that by removing and re-installing using brew. This may happen for other image formats too. Perhaps doing the same for the respective libs might solve the problem.

TL;DR

brew remove libjpeg
brew install libjpeg
