NotIdentifiedByImageMagickError with ImageMagick 6.9.4-7

[mantas]

I updated to ImageMagick 6.9.4-7 on OS X. Now I'm getting NotIdentifiedByImageMagickError. The identify command doesn't seem to work with the [0] suffix to the path. It works fine without the [0] suffix. I was able to reproduce it with GIF, JPG and PNG files.

ImageMagick 6.7.7 seems to work both with and without [0] suffix. I didn't test with older versions though.

The [0] bit is added at:

paperclip/lib/paperclip/geometry_detector_factory.rb

Line 22 in e60f000

:file => "#{path}[0]"

I wonder wether this is a bug on ImageMagick side or they dropped backwards compatibility on this one.

[jasonivers]

There are two more places that use the [0]...
https://github.com/thoughtbot/paperclip/blob/master/lib/paperclip/thumbnail.rb - Line 79 and Line 112.

Removing these makes identify work properly, though I didn't take the time to investigate what else it might break at this time.

Apparently one of the things it does it make it ignore storage: :s3. Goes to show what you get for trying to do a rush job of trying to throw a band-aid on something, rather than trying to understand the actual cause.

Just got bit by this as well after upgrading to the latest version of ImageMagick.

👍 confirming bug, colleague of mine done brew update && brew install imagemagick and boom same error.

another colleague has imagemagic 6.9.1-7 on his mac an it works, so it's only imgemagic 6.9.4-7

Same error here.

I am using imagemagick-6.9.4-7

If you've installed Imagemagick via Homebrew and temporarily need to revert back to the previous version you can do this doing the following.

$ brew uninstall imagemagick
$ cd $(brew --prefix)/Library/Taps/homebrew/homebrew-core
$ git checkout fbc910fd5e9982ce6f39460a05c5975c863903e2 Formula/imagemagick.rb
$ brew install imagemagick
$ git reset --hard HEAD
$ brew update
$ brew upgrade
$ brew switch imagemagick 6.9.4-6

When this issue resolves you can simply switch back to the latest version and run brew cleanup to get rid of the old version.

[michelboaventura]

It seems a bug with imagemagick itself. I has been fixed on master: ImageMagick/ImageMagick#214

[chrisjeon]

@KevinSjoberg that worked. Thanks!

[blakeage]

@KevinSjoberg When I get to the line:

git checkout fbc910fd5e9982ce6f39460a05c5975c863903e2 Formula/imagemagick.rb

I get the following error:
fatal: reference is not a tree: fbc910fd5e9982ce6f39460a05c5975c863903e2

Any ideas?

[lifeiscontent]

@blakeage try brew update first

[blakeage]

@lifeiscontent I tried that, but no luck. I wonder if this is because I tried installing ImageMagick via the --HEAD option

[hovsater]

@blakeage what is the output of brew tap? Also make sure you're in the correct directory, homebrew-core.

[blakeage]

@KevinSjoberg
Blakes-MacBook-Pro:homebrew-core blakemiller$ brew tap
homebrew/boneyard
homebrew/core
homebrew/versions

Blakes-MacBook-Pro:homebrew-core blakemiller$ pwd
/usr/local/Library/Taps/homebrew/homebrew-core

[hovsater]

@blakeage Looks okay to me. You can probably untap homebrew/boneyard but that should not interfere with checking out the proper commit. What does git status give you? What does git log HEAD~5 --grep imagemagick give you?

[blakeage]

@KevinSjoberg I untapped boneyard.

git status returns:

On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean

git log HEAD~5 --grep imagemagick returns/prints nothing.

[hovsater]

@blakeage does git log give you any output? What is the output of git remote -v?

[blakeage]

@KevinSjoberg Yea, git log returns a bunch of commits from today.

git remote -v
origin https://github.com/Homebrew/homebrew-core (fetch)
origin https://github.com/Homebrew/homebrew-core (push)

I'm guessing reinstalling Homebrew may be the way to go?

[hovsater]

@blakeage this is beyond me. I'd try git reset --hard origin/master and/or brew update. Maybe run brew doctor to ensure everything is fine.

[blakeage]

@KevinSjoberg Thanks for the help anyway Kevin. I'll report back if I figure it out.

[lsamayoa]

@blakeage I had the same problem, and it was because homebrew only pulls some commits from the taps (specifically it does a shallow pull). What I´ve done to get arround this is to clone the whole homebrew-tap and replaced my homebrew-tap with the full repository of the tap.

brew uninstall imagemagick
mv $(brew --prefix)/Library/Taps/homebrew/homebrew-core $(brew --prefix)/Library/Taps/homebrew/homebrew-core.old
git clone https://github.com/Homebrew/homebrew-core $(brew --prefix)/Library/Taps/homebrew/homebrew-core
cd $(brew --prefix)/Library/Taps/homebrew/homebrew-core
git checkout fbc910fd5e9982ce6f39460a05c5975c863903e2 Formula/imagemagick.rb
brew install imagemagick
git reset --hard

[mherold]

ImageMagick 6.9.4-8 is now available via homebrew, fixed it for me.

[mantas]

Can confirm that ImageMagick 6.9.4-8 fixes it. Closing this issue.

[YarikST]

Installing libmagickwand-dev seemed to sort it out.

1. sudo apt autoremove imagemagick
2. rm /usr/bin/convert and rm /usr/bin/convert-im6
3. sudo apt-get install imagemagick
4. sudo apt-get install libmagickwand-dev

sudo apt install ffmpeg

ImageMagick delegates video processing. I lost more than 5 hours to understand why such a bug NotIdentifiedByImageMagickError

I hit this problem in Debian Stretch starting around early Dec 2018. I fixed it temporarily by reverting to an older version of ghostscript.
apt-get install libgs9=9.20~dfsg-3.2+deb9u5 ghostscript=9.20~dfsg-3.2+deb9u5 libgs9-common=9.20~dfsg-3.2+deb9u5

My explanation, not yet confirmed, is that the recent update to Ghostscript 9.26 in Debian Stretch Security caused the issue to pop up. Further investigation to do...

[pierre-alain-b]

Being treated here as a bug of ghostscript: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=915832 and https://bugs.launchpad.net/ubuntu/+source/ghostscript/+bug/1806517
