Dyld: library not loaded: /usr/local/opt/icu4c/lib/libicui18n.62.dylib

Question

Problem :

Currently I am learning Homebrew (Mojave). Recently I tried to install the node using Homebrew (Mojave) but after sometime my  Php stopped working and now if I try to run the command php -v I face below error:

php -v
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.62.dylib
  Referenced from: /usr/local/bin/php
  Reason: image not found

I have also tried to uninstall my both node and icu4c but my problem still persists

Answer 1

I you are facing above error then you sould try below command

 brew switch icu4c 62.1 Note : This command will only work if you have already installed the 62.1 in the past. If you don’t have it then you need to follow detailed procedure as given below:

The first step is to deep clone the Homebrew repo. It will take some time: 

git -C $(brew --repo homebrew/core) fetch --unshallow

brew log icu4c use this command to track down the commit that references the 62.1.

Then you should execute the commands exactly as shown below:

cd $(brew --repo homebrew/core)

git checkout 575eb4b -- Formula/icu4c.rb

brew uninstall --ignore-dependencies icu4c

brew install icu4c 

Now you should be having the correct version of your dependency. Now just to cleanup the modified recipe execute below command.

git reset && git checkout

Now your issue must be resolved.
