Homebrew + Imagemagick + php54-imagick not working

Question

Based on this post here, I am having a versioning issue with Imagemagick.

• php54-imagick version => 3.4.3_2
• imagemagick => 7.0.5-3

I understand that I need to downgrade my imagemagick to 6.9.*

My issue:

brew install php54-imagick

Automatically installs the required imagemagick 7.0.5-3 package

-

I uninstall imagemagick 7.0.5-3

brew uninstall --ignore-dependencies imagemagick

-

I install imagemagick 6.9.* (6.9.8-1 to be specific)

brew install imagemagick@6

The error:

macos1:~ $ php -i | grep imagick

The question:

How would I use php54-imagick version 3.4.* with imagemagick 6.9.*?

Answer 1

I have resolved my own issue! Since I was using the readImage method from ImageMagick class, it required ghostscript to be installed alongside ImageMagick.

However, when you brew install imagemagick, ghostscript is an optional dependency that is not installed by default.

To resolve my issue, here is what I did (all the steps):

1. brew install php54-imagick
2. brew install imagemagick --with-ghostscript

Now I can readImage('test.pdf')!

Answer 2

I had the same issue but when upgrading from PHP 7.0 to PHP 7.1. The error has gone away after reinstalling the imagick extension from source:

brew reinstall -s php71-imagick

I guess it may work for other PHP versions. Just replace the php71 from the command above by your version. For example: php56 or php70.
