react-native: dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.58.dylib

try npm version and see if you see the same error. If so, try to upgrade your node version brew upgrade npm and

==> Upgrading 1 outdated package, with result:
npm 8.1.2 -> 10.3.0
==> Upgrading npm
==> Installing dependencies for node: icu4c
==> Installing node dependency: icu4c

fixed for me.

this is the correct solution: brew uninstall --ignore-dependencies node icu4c brew install node brew link --overwrite node

Hey, so I solved a similar issue just now.

I was using React (not React Native) and was trying to sniff php code, but the error I got took the same form as yours:

dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.61.dylib
  Referenced from: /usr/local/opt/php@7.1/bin/php
  Reason: image not found

What solved my issue was updating npm from 5.6.0 to 6.1.0 with npm i -g npm, then reinstalling php with brew reinstall php@7.1.

I’d imagine that doing brew reinstall node would work for you since your error references your node install. But you aren’t using homebrew… maybe as a last-ditch effort you could try installing it. I think the problem is likely with your node install though. Hope this helps and good luck!

Worked for me, had an issue with Laravel Valet and Composer.

I got a new MBP and did a migration from my old one, but was getting this error while building my app for android. Doing the following worked for me:

sudo chown -R $(whoami) /usr/local/Cellar
brew uninstall --force yarn
brew uninstall --force icu4c
brew uninstall --force node
brew install node
brew install yarn

brew update && brew upgrade worked for me. Dependency hell is fun.

Dear future person searching to fix this problem. brew update & brew upgrade worked for me too!! Haha

+1 same problem

brew info icu4c you can see something like this /usr/local/Cellar/icu4c/63.1 or /usr/local/Cellar/icu4c/62.1 or /usr/local/Cellar/icu4c/56.1 or /usr/local/Cellar/icu4c/58.1

cd /usr/local/Cellar/icu4c/58.1/lib then cp ./libicui18n.58.dylib /usr/local/opt/icu4c/lib/

I hope i can help you
