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

[stevensacks]

• [X] I have reviewed the documentation
• [X] I have searched existing issues
• [X] I am using the latest React Native version

I get the following error when I try to build my react native app in XCode:

dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.58.dylib
  Referenced from: /usr/local/bin/node
  Reason: image not found 

All of the things I've found on google talk about reinstalling node using homebrew. However, I'm not using node via Homebrew, my node is installed via nvm.

Any help would be much appreciated.

Environment

Environment:
OS: macOS High Sierra 10.13.4
Node: 9.9.0
Yarn: 1.3.2
npm: 5.7.1
Watchman: 4.9.0
Xcode: Xcode 9.3 Build version 9E145
Android Studio: Not Found

Packages: (wanted => installed)
react: ^16.3.1 => 16.3.1
react-native: ^0.55.1 => 0.55.1

Steps to Reproduce

This is a project which builds fine on my client's machine and my laptop. It is only not working on my desktop computer.

Expected Behavior

I thought it would build.

Actual Behavior

It doesn't build because of the above error.

Yes.

I have tried completely uninstalling and reinstalling node. I have tried reinstalling icu4c manually. I have tried older versions of node, I have tried the latest version of node 9.11.1. I have updated my chown permissions. I have tried everything I could find on google related to this error. Nothing works.

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 Upgrading 1 outdated package, with result: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.

I re-install yarn and upgrade my node version with nvm.

I have still don't know what problem happened with it...but it's work again for me.

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/[email protected]/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 [email protected].

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!

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

[heshamelmasry77]

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

Make sure everything is up to date.
Update brew using brew update
Update packages using brew upgrade

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

Updating yarn fixed the problem for me brew upgrade yarn

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

This worked for me except I had to do

This worked for me.

[zlanich]

brew cleanup and/or brew reinstall php7.2 seems to have done it for me. I also did brew update && brew upgrade and reinstalled yarn and all that before that.

[qingdujun]

This worked for me!
