dyld: Library not loaded: /usr/local/lib/libjpeg.8.dylib - homebrew php

Question

PHP was not working for me as I was encountering this libpng issue, so I reinstalled a new version with Homebrew.

However, I\'m getting a similar error with

Answer 1

A dirty solution, that work fine for me.

ln -s /usr/local/lib/libjpeg.9.dylib /usr/local/lib/libjpeg.8.dylib

Answer 2

I had also this problem. I solved it in this way: Uninstall jpeg/8b:

brew uninstall --ignore-dependencies libjpeg

Uninstall jpeg/9b:

brew uninstall --ignore-dependencies jpeg

Re install jpeg/9b

brew install jpeg

Answer 3

I am sharing this as I had the same issue when using PHP5.4. Originally, I had PHP5.6 and it was working fine. Then I downgraded to php5.4 as my app only supports PHP5.4.

Then this error came up. I noticed that I have libjpeg.9.dylib and PHP5.4 is looking for libjpeg.8.dylib.

Doing the following sorted the issue:

brew uninstall php54
brew install --build-from-source php54

Answer 4

I was getting a similar problem trying to upgrade composer:

dyld: Library not loaded: /usr/local/opt/jpeg/lib/libjpeg.8.dylib
Referenced from: /usr/local/bin/php
Reason: image not found
composer: PHP Phar support is required for this formula
Error: An unsatisfied requirement failed this build.

Problem was php couldn't find libjpeg library anymore. One way to fix this is to reinstall php and libjpeg. Here's how I reinstalled them:

# find out which version of php is installed
brew list | grep php

# uninstall php
brew uninstall php70 --ignore-dependencies

# uninstall libjpeg
brew uninstall libjpeg --ignore-dependencies

# install libjpeg again
brew install libjpeg

# install php again
brew install php70

I was then able to upgrade everything again :)

brew update && brew upgrade

Answer 5

I was having the same problem and the only thing that helped was to use the --build-from-source parameter:

brew install php70 --build-from-source

Answer 6

I encountered the similar problem today. The cause of the problem was a newer version of libjpeg. And the solution that worked was building php bottle from source.

Check available version of libjpeg:

$brew info libjpeg
jpeg: stable 9b (bottled)
Image manipulation library
http://www.ijg.org
/usr/local/Cellar/jpeg/9b (20 files, 724KB) *
  Poured from bottle on 2017-08-07 at 12:06:42
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/jpeg.rb

Install php from source:

brew install --build-from-source php56

Update:
If you have already installed php you have to uninstall it prior to building from source. It also applies to extensions.
