ImageMagick 7 with RMagick 2.16 on MacOS Sierra Can't find MagickWand.h

Question

I upgraded to imagemagick-7.0.4-3.sierra and now my previously installed RMagck 2.16 fails. I checked for MagicWand:

$ find /usr/local -name MagickWand.h /usr/local/Cellar/imagemagick/7.0.4-3/include/ImageMagick-7/MagickWand/MagickWand.h

So it seems to be there. Also I reinstalled and relinked pgk-config. Didn't help as well. Any ideas?

I temporary fix is to downgrade to the latest imagemagick6 brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/6f014f2b7f1f9e618fd5c0ae9c93befea671f8be/Formula/imagemagick.rb — anny_goerl, Jan 14 '17 at 13:06
it helped me a lot, thanks! so the solution is: `brew uninstall imagemagick`, then `brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/6f014f2b7f1f9e618fd5c0ae9c93befea671f8be/Formula/imagemagick.rb` — Avael Kross, Jan 14 '17 at 15:13

I have just encountered and solved this issue on a new Mac running Sierra. There seems to be no solution for ImageMagick 7 at this time.

Uninstall existing imagemagick if needed
Install version 6:

brew install imagemagick@6
Since this is keg-only, you should then force-link it:

brew link --force imagemagick@6

This installed imagemagick version 6.9.7-4 for me.

Afterwards, the gem then installed successfully. I am including the version numbers for future readers:

Installing rmagick 2.13.4 with native extensions

I didnt find a solution for making rmagick to work with imagemagick v7, falling back to v6 works as described in this answer, thanks – mmln Jan 20 '17 at 21:23

I found this 2 hours in. I want to throw my computer out a window. – Brian Feb 09 '17 at 19:47
I opened an issue: https://github.com/rmagick/rmagick/issues/265 Let's see if they add this to the documentation. – Daniel Feb 14 '17 at 04:15
Thanks @Daniel. You're a champ. – dyson returns Feb 14 '17 at 09:39

had to run `echo 'export PATH="/usr/local/opt/imagemagick@6/bin:$PATH"' >> ~/.bash_profile` after the above steps. hope it helps others. – Yunwei.W May 02 '17 at 06:12
@Yunwei.W Are you sure you uninstalled other versions of imagemagick and that you definitely force-linked it? – dyson returns May 02 '17 at 14:56
Thank you! Worked great on Sierra – utahtwo May 07 '17 at 14:10
If you'd prefer not to load all of ImageMagick's binaries onto your PATH, you can also run `export PKG_CONFIG_PATH=/usr/local/opt/imagemagick@6/lib/pkgconfig` – caleb531 Oct 15 '17 at 23:46
I needed both --force AND --overwrite: `brew link --force --overwrite imagemagick@6` Otherwise this worked! – Peter H. Boling May 01 '18 at 02:51

dyson's solution didn't quite work for me. I found that in addition to installing imagemagick@6, I also need to install pkg-config and then set PKG_CONFIG_PATH.

brew install imagemagick@6 pkg-config
PATH="/usr/local/opt/imagemagick@6/bin:$PATH" PKG_CONFIG_PATH=/usr/local/opt/imagemagick@6/lib/pkgconfig gem install rmagick -v '2.13.4'

I prefer this solution because I don't have to remove the global linking to the latest ImageMagick version. – Valdis Sep 26 '18 at 07:32
@TheLazyLog I think the problem with other solutions is that they assume you have stuff like pkg-config installed – after some time of using homebrew, one will definitely wind up with pkg-config on their computer. I was setting up a fresh Mac so that assumption just wasn't true for me. – Rafał Cieślak Feb 14 '19 at 11:04
