dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.62.dylib error running php after installing node with brew on Mac

Question

I installed node using homebrew (Mojave), afterwards php stoped working and if I try to run php -v I get this error:

php -v
dyld: Library not lo         


        

Answer 1

In my case, brew update icu4c to version 67.1 so my php7.1 doesn't work. Just reinstall icu4c, then it fine.

Answer 2

This fixed it for me:

brew upgrade node

Answer 3

Just brew remove php and brew install php did not work, nor did brew reinstall php. My solution was to do:

brew remove php
cd /usr/local/Cellar
rm -rf php/
brew install php
brew doctor
brew cleanup

Now php -v gives me:

PHP 7.3.2 (cli) (built: Feb 14 2019 10:08:45) ( NTS )

Answer 4

Got this error, too, after installing php 7.3. I had it resolved upgrading just my old php's versions (5.6 and 7.0, not from the official repos).

The maintainers had compiled new php versions against the current icu4c.

In my case, PHP 7 got from 0.31 to 0.33, and the problem was solved.

Answer 5

In my case I had to switch between two versions of icu4c since I still maintain PHP 5.6 projects (which use the old icu4c 64.2). brew install and reinstall from raw .rb links always replaces the previously installed versions for some reason.

#fetching 64.2
brew fetch https://raw.githubusercontent.com/Homebrew/homebrew-core/a806a621ed3722fb580a58000fb274a2f2d86a6d/Formula/icu4c.rb 

#fetching stable version
brew fetch https://raw.githubusercontent.com/Homebrew/homebrew-core/master/Formula/icu4c.rb 

cd $(brew --cache)/downloads

mv -n icu4c/67.1 $(brew --cellar)/icu4c/
mv -n icu4c/64.2 $(brew --cellar)/icu4c/

then switch between versions

$ brew switch icu4c 64.2

Cleaning /usr/local/Cellar/icu4c/67.1
Opt link created for /usr/local/Cellar/icu4c/64.2

Answer 6

I am actually quite surprised that this solution has not been presented yet, and I feel like it is the easiest solution.

Go to GitHub, find the version of the brewfile that matches the version of icu4c that you need and get the raw version of the file (follow the links above and click View File then Raw).

Then just have brew reinstall from that url.

For example, version 62.1:

brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/575eb4bbef683551e19f329f60456b13a558132f/Formula/icu4c.rb

For example, version 64.2:

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