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

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 🚀

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

<3

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

Thank you. It worked.

Thank you, this woked for me .

Thanks - this saved me a lot of time!

👍

"brew upgrade node" works, thanks

I tried everything here and this is the only approach that worked for me:
https://stackoverflow.com/a/55828190

The original stackoverflow question there matched my situation exactly. If you're having a slightly different version of icu4c requested by your errors (not 63), then you should modify the instructions to match your situation. So, for example, if you're seeing errors trying to find version 62, then in the git log step you need to find the commit hash corresponding to version 62 and use that in place of the commit hash in the next step in the answer.

After trying all of the above with no luck, this worked for me:
brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/e7f0f10dc63b1dc1061d475f1a61d01b70ef2cb7/Formula/icu4c.rb
Hope it helps

Gracias me funcionó

I was able to find a way to have icu4c version 60.2 on macOS Catalina, version 10.15.3.

To get the version 60.2 of icu4c, run these commands:

brew install node
brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/fb928fcb69debc71e9fbaf2ada5919f180f9667c/Formula/icu4c.rb
brew switch icu4c 60.2

This brings in node version 13.8.0 and icu4c version 64.2 on Catalina. icu4c 60.2 is no longer available from just running brew install icu4c@60.2 so it has to be reinstalled from the specific commit that had the information available to install it.

This commit is where version 60.2 was added to homebrew-core:

Homebrew/homebrew-core@86ff03f

But they didn't do the checksums until this commit, which is used above:

Homebrew/homebrew-core@fb928fc

Any commit up until they pulled that install code can be used for version 60.2. The other option is to bring in an older version of node (8, I think) from around the High Sierra days, which depends on icu4c 60.2. Node@10 is the oldest available in Catalina, but that still depends on icu4c 64.3, so digging through commits is needed for older versions of Node.

Node 13 itself won't run until you switch its dependency back to the current version of icu4c:

brew reinstall icu4c

@humphriest's comment above will bring in icu4c version 63.1 and @forresthopkinsa's comment will bring in version 62.1

As as additional suggestion to @em77's very astute reference: an easy way to find the commits for various versions of icu4c is to search homebrew-core's Github:

https://github.com/Homebrew/homebrew-core/search?q=icu4c+60.2&type=Commits

Thanks!! work form me too

Thanks! work for me

Thanks @em77! Your information helped me to solve this problem.

Thank you. Works for me.

brew upgrade node

Thanks, it saves me a lot of time.

Thanks @dalmau brew upgrade node worked for me on Mac OS Catalina.

Thank you it work like a charm!

brew switch icu4c 64.2

work for me!

Many thanks @berkedel

brew reinstall php@7.1
or
brew reinstall php@7.2

I think the problem is with php.

works for me

just re install php
brew reinstall php

brew reinstall php@7.3 works for me

I'm using node@12 - a brew reinstall node@12 fixed this for me.

brew reinstall php@7.2 did the trick for me. Thanks, everyone!

Ultimately I switched to NVM as that manages Node and NPM far better and allows for installing down to minor and patch versions like 12.12.0 rather than Brew installing at a major version only.
Lots of the above suggestions didn't work. My issue was an installed version I was unaware of that prevented linking any new versions installed.
Find all node versions, take note of the versions listed but uninstall all of them, then install the version you need.

brew search node
brew uninstall --ignore-dependencies node@12 icu4c --force
brew install node@10
brew link node@10

brew reinstall php :)

brew reinstall php works for me 🎉

Worked for me, thanks

In case you need to install 66.1

cd $(brew --prefix)/Homebrew/Library/Taps/homebrew/homebrew-core/Formula
git checkout -b icu4c 22fb699a417093cd1440857134c530f1e3794f7d
brew reinstall ./icu4c.rb

I'm gonna be the 500th to say this but yes, this worked, thank you very much!

After 1million year,
This post will remain helpful.

Worked for me too, Cheers :D

Does everyone here actually understand what this does:

brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/896d1018c7a4906f2c3fa1386aaf283497db60a2/Formula/icu4c.rb

Call me paranoid but I'm a bit uncomfortable with running a script like this which I really don't understand.....

This:
(1) brew uninstall --ignore-dependencies node icu4c
(2) brew install node

worked perfectly.

@m6t6ng6 Thanks!!

The first solution (uninstall + reinstall) worked for me, thanks so much!

So this upgraded my local node version from 12 to the latest version 14.

Was no big deal, just had to update node-sass too. I'm sure this may be the case with other modules depending on what you're doing.

Here was the message, pretty straight forward:

Error: Missing binding /Users/xxx/xxx/xxx/xxx/node_modules/node-sass/vendor/darwin-x64-83/binding.node
Node Sass could not find a binding for your current environment: OS X 64-bit with Node.js 14.x

Found bindings for the following environments:
  - OS X 64-bit with Node.js 12.x

This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to download the binding for your current environment.

If you don't know what's breaking your library dependency and you're using brew try this which worked for me:

brew uses --installed icu4c | xargs brew reinstall

This error happened right after I installed Encore into my solution.
Running brew reinstall php@7.4 did the trick for me
Adapt this with your php version if you run into the same problem.

old postgresql 12.2 tryna seek out /usr/local/opt/icu4c/lib/libicui18n.64.dylib however the mac os has libicui18n.67.dylib so upgrade it to 12.3_4 is a simple solution for me.

brew uninstall and re install worked perfectly

Original solution worked for me, thanks!

thanks 👯

worked thanks!

@Razoxane solution worked for me!

Does everyone here actually understand what this does:

Call me paranoid but I'm a bit uncomfortable with running a script like this which I really don't understand.....

It's installing the version of icu4c as it specifically was in the version of the code in commit 896d1018c7a4906f2c3fa1386aaf283497db60a2
You can look at the repo here: https://github.com/Homebrew/homebrew-core/tree/896d1018c7a4906f2c3fa1386aaf283497db60a2

also works ->
