How to solve dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.60.dylib

brew uninstall --ignore-dependencies node icu4c
brew install node

Heya. This doesn't solve my issue by itself unfortunately :) While reinstalling node this pops up:

==> Pouring node-10.1.0.high_sierra.bottle.tar.gz Error: The "brew link" step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/node
Target /usr/local/bin/node
is a symlink belonging to node. You can unlink it:
brew unlink node

To force the link and overwrite all conflicting files:
brew link --overwrite node

Gotta run brew link --overwrite node to make it work.

this worked for me, thanks :)

Also worked for me! Thank you! :)

Thank you, this worked for me.

Thank you, also works for me!

Thanks, this worked. In my case, I use a versioned node, node@8, so I had to just run

brew uninstall --ignore-dependencies node@8 icu4c
brew install node@8

node@8 solution worked 4 me, thx

it worked for me, thank you.

Worked for me too: thank you!

thanks

I reinstall php with brew reinstall php@7.1 to solve this problem.

Thanks! brew link --overwrite node solved!

Thanks, solved my issue!

I had multiple versions of icu4c, so I had to run brew uninstall --force icu4c before reinstalling node. Then it worked perfectly for me.

It works for me, thanks.

+1

node@8 worked for me too, thanks.

It works for me, thanks.

Nice one

Confirming that still works. Thanks.

This was such a weird error. Thank you internet.

Thanks a lot for this!

thanks for this!

brew reinstall php@7.1

thanks for mentioning that ! i had laravel valet with php@7.1 and did brew reinstall php which didn't solve the issue...

+1 👍

I had an old manually linked version of php 5.6 under /usr/local/bin/php, so php broke when I upgraded to 7.2. Deleting the old symlink allowed the newer PHP version to kick in.

Thanks!

Thank you. This confirmed works.

brew reinstall php@7.1
or
brew reinstall php@7.2

I think the problem is with php.

I concur that my issue was with php, with both php and composer commands failing with this issue. Anyone have any idea what could've changed? I don't recall really doing anything to break it recently; it appears to have done it of its own accord.

Either way, brew reinstall php@7.2 worked for me

brew reinstall php@7.2 worked for me as well!

brew reinstall php@7.2 worked for me as well!

I got this problem when I installed php 7.3
The solution solved my issue.

Worked for me too!

Thanks, worked for me

Worked for me too. Much thanks <3

good tip, thanks for the contribution ! 👌

Thanks!

also works ->

brew upgrade node
Upgrading 1 outdated package:
node 10.9.0 -> 11.6.0

Work for me too. Thanks!

I had this same error with Postgresql. brew install postgresql fixed it.
Be cautious if you have important data in Postgres though... Most major DB versions can't read data files from last version.
(I had other issues after this too... but they were psql related and easier to debug)

@abelorian thanks. That did the trick!

This worked, thank you! (though, I tried it without "icu4c" at the end)

Fixed my problem, thx !

Does anybody actually know WHY this could happen ? Because only re-installing or re-linking will not solve the root cause, if a root cause exists.

I think this could happen by installing php after node, don't know why or how, but it's the only thing that changed on my computer since this appear.

Thanks, worked for me ;=)

Thanks :)

Doesn't work for me, neither for node, yarn or php

* BANG *

Thanks !!

looks like everyone has been having a slightly different issue.

What worked for me, which is a variation (simpler?) from what @bpolaszek posted:

brew uninstall node icu4c node --ignore-dependencies --force
brew install node

brew reinstall node should fix the issue

For those who got this issue after brew upgrade node its just a linking issue for the new binary use
brew link --overwrite node did the trick for me

brew reinstall php@7.1 worked for me ,thanks

Awesome, thanks!

brew reinstall php@7.2 worked for me as well!!! ty !

As someone running into this issue trying to build an ionic ios app, this worked for me, thank you!

Here is my particular error:

I did have the icu4c library but the xcode build script was looking for the wrong version.

A much simpler solution will probably work for 2019 users

As mentioned in this SO answer, you very likely only need to switch your icu4c from version 63 to version 62:

brew switch icu4c 62.1

A bit less extreme method.

works great! thanks!

Thanks @trainoasis, brew link --overwrite node worked for me.

Thanks. That worked for me.

Worked for me too. thanks :)

👍

Thanks @trainoasis, brew link --overwrite node worked for me as well 🚀

brew reinstall php@7.2 worked for me as well. Thx!

👍, thanks

@forresthopkinsa Thanks this worked for me!

@alexbrohman glad I could help!

Much better and simpler solution. Especially for people that installed Node through NVM and do not want it installed through brew at all.

Has anyone fixed this without brew link --overwrite node? This seems like a bad idea for anyone who is managing their node version with nvm, like myself.

@forresthopkinsa brew switch icu4c 62.1 gave me an error that 62.1 is not installed. I attempted brew install icu4c@62.1 but this didn't work and it seems that installing a specific version in brew may be non-trivial.

@rm-rf-etc Try the following:

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

You're right it's non-trivial, I had to do a lot of digging to get those commands. Let me know if they work for you.

@berkedel you're my hero for today. Thank you :)

Thank you
