After upgrading to Node v.10.9.0 via Homebrew the following error message was thrown from PHP:

dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.61.dylib
  Referenced from: /usr/local/bin/php
  Reason: image not found

Reinstall PHP to fix, for me that's:

brew reinstall [email protected]

  1. stop all php-fpm services
  2. brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/a806a621ed3722fb580a58000fb274a2f2d86a6d/Formula/icu4c.rb
  3. copy libicui18n.64.dylib from /usr/local/opt/icu4c/lib/ (MacOS, Mojave, 10.14.6) to save any location
  4. brew reinstall icu4c
  5. ls -al /usr/local/opt/icu4c/lib/ - you have to see libicui18n.66* and absent libicui18n.64.dylib
  6. copy libicui18n.64.dylib back to /usr/local/opt/icu4c/lib/
  7. start your php-fpm services
  8. if some troubles with php-fpm – see logs at /usr/local/var/log/php-fpm.log (probably location)

Thanks Bro, PHP 5.6 vs PHP 7.3 is works ok.

But not just copying 1 file, but copying multiple files with the same file name libicu * .64.dylib

Your welcome, Bro. But I copied the one file exactly. May be some difference with OS and your advice will help some other.

I had the same issue here, running brew reinstall icu4c
Error: Calling Installation of icu4c from a GitHub commit URL is disabled! Use 'brew extract icu4c' to stable tap on GitHub instead.

The solution for me was to run it while being in php 7.2, then switch back to 7.1:
brew install [email protected]
brew unlink [email protected]
brew link [email protected] --force
brew reinstall icu4c
brew unlink [email protected]
brew link [email protected] --force

After reinstalling php , nothing worked , so I had to do
export PATH="/usr/local/opt/[email protected]/bin:$PATH" >> ~/.zshrc
Then it my php artisan serve worked back

For me, "brew reinstall icu4c" configured and "make"-ed php7.1 for the newer icu4c.. problem solved! :)

For me, upgrade node (brew upgrade node) from 13.6.0 to v15.2.0 solved the problem

If you cannot reinstall from url, simply download and use the local file.

Instead of

brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/a806a621ed3722fb580a58000fb274a2f2d86a6d/Formula/icu4c.rb

Simply do something like

wget https://raw.githubusercontent.com/Homebrew/homebrew-core/a806a621ed3722fb580a58000fb274a2f2d86a6d/Formula/icu4c.rb
brew reinstall icu4c.rb

Expanding on @Ardakilic's comment:

To be even more explicit and break down what is going on here:

  1. Go here in your web browser:
    https://raw.githubusercontent.com/Homebrew/homebrew-core/a806a621ed3722fb580a58000fb274a2f2d86a6d/Formula/icu4c.rb

  2. Copy paste the contents into a text file named:
    icu4c.rb

  3. Run:
    brew reinstall icu4c.rb

I just write this to make it clear it's only a text file being downloaded, not rocket surgery.

(I was stumped on this for a while until I looked at contents of the .rb files)

Update Hopefully now I have a proper solution for this. @jv2222 you should also check this:

Icu4c reinstallation made me force reinstall PHP8, which broke the purpose for me. So, I have found some new repositories where you don't need to hassle with this icu4c stuff at all:

brew install shivammathur/php/[email protected]
brew install shivammathur/php/[email protected]
brew install shivammathur/php/[email protected]
brew install shivammathur/php/[email protected]
brew install shivammathur/php/[email protected]
brew install shivammathur/php/[email protected]
brew install shivammathur/php/[email protected]

First, delete all php installations with a command something like brew uninstall "php*" and brew unlink [email protected]

You may also need to untap other taps. I had to run

brew untap exolnet/deprecated

to install properly.

Then, if you want, delete the /usr/local/etc/php folder

then install one of the packages I've linked above.

Worked Nicely for PHP 7.1:

➜  ~ php -v
PHP 7.1.33 (cli) (built: Dec  1 2020 01:14:43) ( NTS )

Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.1.33, Copyright (c) 1999-2018, by Zend Technologies

You can also quickly switch between php versions with a command like:

brew unlink php && brew link --overwrite --force [email protected]

etc.
