ImageMagick error

Question

When trying to run ImageMagick via node-imagemagick on my Grunt task, i get this error from ImageMagick:

Warning: Command failed: identify: unable to load module /usr/local/Cellar/imagemagick/6.8.8-9/lib/ImageMagick//modules-Q16/coders/jpeg.la': file not found @ error/module.c/OpenModule/1275. identify: no decode delegate for this image formatinventaire/videos/OFF_Arrestation joueur_14_petit.jpg' @ error/constitute.c/ReadImage/501. Use --force to continue.

Why is ImageMagick trying to load JPG coder at /usr/local/Cellar/imagemagick/6.8.8-9/lib/ImageMagick//modules-Q16/coders/jpeg.la? Why the double slash after ImageMagick// ?

This grunt script run perfectly on OSX 10.8 and now fail on 10.9.2. Anyone know a way to fix it?

Answer 1

I came across this issue too when upgrading from Mt.Lion to Mavericks. I found an issue in homebrew's github repo. The fix that worked for me was:

$ brew uninstall imagemagick $ brew install imagemagick --build-from-source 

Answer 2

OSX Mavericks seems break the link of jpeg lib. All you need to do is relink the jpeg, then reinstall imagemagick.

brew unlink jpeg brew link jpeg 

Then reinstall imagemagick from source

brew uninstall imagemagick brew install imagemagick --build-from-source 

Now you can check if jpeg is in the delegate

identify -list configure | grep DELEGATES 

It should have jpeg now

DELEGATES bzlib mpeg freetype jng jpeg lcms lzma png tiff xml zlib
