dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.62.dylib error running php after installing node with brew on Mac

Question

I installed node using homebrew (Mojave), afterwards php stoped working and if I try to run php -v I get this 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 tried to uninstall both node and icu4c but the problem persists

Answer 1

Update - As stated in some of the comments, running brew cleanup could possibly fix this error, if that alone doesn't fix it, you might try upgrading individual packages or all your brew packages.

I just had this same problem. Upgrading Homebrew and then cleaning up worked for me. This error likely showed up for me because of a mismatch in package versions. None of the above solutions resolved my error, but running the following homebrew commands did.

Caution - This will upgrade all your brew packages, including, but not limited to PHP. If you only want to upgrade specific packages make sure to be specific.

brew upgrade icu4c

brew upgrade // or upgrade all packages

and finally

brew cleanup

Answer 2

In my case, that happened because icu4c was upgraded to version 63 but my locally installed postgres image still referenced icu4c 62.1. Therefore I had to change the icu4c version used:

 brew info icu4c
 brew switch icu4c <version>

Where version is the installed version returned by info.

Answer 3

I am actually quite surprised that this solution has not been presented yet, and I feel like it is the easiest solution.

Go to GitHub, find the version of the brewfile that matches the version of icu4c that you need and get the raw version of the file (follow the links above and click View File then Raw).

Then just have brew reinstall from that url.

For example, version 62.1:

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

For example, version 64.2:

brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/a806a621ed3722fb580a58000fb274a2f2d86a6d/Formula/icu4c.rb

UPDATE:

Later versions of Homebrew may require you to download the file first. If this is the case:

wget https://raw.githubusercontent.com/Homebrew/homebrew-core/a806a621ed3722fb580a58000fb274a2f2d86a6d/Formula/icu4c.rb
brew reinstall icu4c.rb

Answer 4

Run npm version, if you see the same error, upgrade npm.

brew upgrade npm.

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 Upgrading 1 outdated package, with result: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

Answer 5

Turns out I, like @Grey Black, had to actually install v62.1 of icu4c. Nothing else worked.

However, brew switch icu4c 62.1 only works if you have installed 62.1 in the past. If you haven't there's more legwork involved. Homebrew does not make it easy to install previous versions of formulae.

Here's how I did it:

1. We first need a deep clone of the Homebrew repo. This may take a while: git -C $(brew --repo homebrew/core) fetch --unshallow
2. brew log icu4c to track down a commit that references 62.1; 575eb4b does the trick.
3. cd $(brew --repo homebrew/core)
4. git checkout 575eb4b -- Formula/icu4c.rb
5. brew uninstall --ignore-dependencies icu4c
6. brew install icu4c You should now have the correct version of the dependency! Now just to...
7. git reset && git checkout . Cleanup your modified recipe.
8. brew pin icu4c Pin the dependency to prevent it from being accidentally upgraded in the future

If you decide you do want to upgrade it at some point, make sure to run brew unpin icu4c

Answer 6

For me the solution was to:

brew reinstall icu4c

Then

gem uninstall charlock_holmes
gem install charlock_holmes

Answer 7

I had the same problem after I upgraded my macOS to version 10.13.6. I can't run composer and php commands. After researching for a while and trying various solutions posted online, reinstalling php using homebrew worked.

brew reinstall [email protected]

Added on March 14th based on Ryan's comment

get the version you are currently using by running php -v and get the right formulae (which you can find here: https://formulae.brew.sh/formula/php) to replace @7.1 in the above command.

Answer 8

This fixed it for me:

brew upgrade node

Answer 9

I actually tried all of the solutions which made sense, mentioned in this post and yet i still got the same error when running php -v or composer. The node version was fine, npm as well there were no issues on having installed correct versions and they were all running. Running reinstall [email protected] just threw an error. In the end i had to run:

brew reinstall icu4c

This basically worked, with me having to manually then install php dependencies such as imagick.so, imap.so As these libraries were installed for a project that i no longer maintain i can go without them. But if you do have dependancies on them, have in mind that there will be more work to do afterwards.

Answer 10

Seems like it is impossible to link icu4c using brew after latest OS X update. Which makes things more interesting. The only solution I found working for me:

1. Download and compile icu4c 62.1 to /usr/local/icu4c/62.1

mkdir ~/sources
cd ~/sources
wget http://download.icu-project.org/files/icu4c/62.1/icu4c-62_1-src.tgz
tar xvzf icu4c-62_1-src.tgz
cd icu/source/

sudo mkdir /usr/local/icu4c/62.1
./configure --prefix=/usr/local/icu4c/62.1
make
sudo make install

2. Link libs:

ln -s /usr/local/icu4c/62.1/lib/*.dylib /usr/local/include/

3. Set DYLD_LIBRARY_PATH in ~/.bash_profile:

export DYLD_LIBRARY_PATH=/usr/local/include

Answer 11

Just brew remove php and brew install php did not work, nor did brew reinstall php. My solution was to do:

brew remove php
cd /usr/local/Cellar
rm -rf php/
brew install php
brew doctor
brew cleanup

Now php -v gives me:

PHP 7.3.2 (cli) (built: Feb 14 2019 10:08:45) ( NTS )

Answer 12

my issue:

# npm install -g canvas

dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.64.dylib
  Referenced from: /usr/local/opt/node@8/bin/node
  Reason: image not found

for now 20210118, after many try:

...
brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/master/Formula/icu4c.rb
brew upgrade npm
brew install node
brew uninstall --ignore-dependencies node@8 icu4c
brew install icu4c
...

Final worked solution is:

brew reinstall npm

2021-02 Easy solution

After years of dealing with this problem the following, surprisingly easy, solution worked for me:

1. Open the raw file in your web browser of the version you need:

Version 62: https://raw.githubusercontent.com/Homebrew/homebrew-core/575eb4bbef683551e19f329f60456b13a558132f/Formula/icu4c.rb

Version 64: https://raw.githubusercontent.com/Homebrew/homebrew-core/a806a621ed3722fb580a58000fb274a2f2d86a6d/Formula/icu4c.rb

Version 66: https://raw.githubusercontent.com/Homebrew/homebrew-core/22fb699a417093cd1440857134c530f1e3794f7d/Formula/icu4c.rb

Version 67: https://raw.githubusercontent.com/Homebrew/homebrew-core/88b9cc789820f2f544d8d4a1053eebb044c2926c/Formula/icu4c.rb

Latest version: https://raw.githubusercontent.com/Homebrew/homebrew-core/master/Formula/icu4c.rb

2. Copy paste the contents into a new file named: icu4c.rb
3. Run the following on the newly created file: brew reinstall icu4c.rb

Source: https://gist.github.com/hgrimelid/703691ab48c4a4d0537cfe835b4d55a6

Answer 14

For me it was appearing for node@12 And the following steps worked for me -

brew uninstall --ignore-dependencies icu4c
brew install node

which installed icu4c automatically and fixed the whole thing.

Answer 15

For me brew reinstall nodejs fixed this - my issue was with running Elixir/Phoenix so not PHP specific, I think it was caused by brew install postgres, but reinstalling that didn't help. I was getting it from npm commands.

Answer 16

Actually, I found the solution directly on homebrew page: https://docs.brew.sh/Common-Issues

Upgrading macOS can cause errors like the following:

• dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.54.dylib configure: error: Cannot find libz
• Following a macOS upgrade it may be necessary to reinstall the Xcode Command Line Tools and brew upgrade all installed formula:

xcode-select --install
brew upgrade

In my case the problem wasn't related to upgrading OS, but the solution worked nicely.

Answer 17

On mac, anything related to node was not working for me. Running this solved the problem:

brew reinstall node

Answer 18

brew update && brew upgrade worked for me

Answer 19

i followed this article here and this seems to be the missing piece of the puzzle for me:

brew uninstall node@8

Answer 20

In order to downgrade, i had to recompile from source (MacOS Mojave)

$ wget https://ssl.icu-project.org/files/icu4c/62.1/icu4c-62_1-src.tgz
$ tar xvfz icu4c-62_1-src.tgz
$ cd icu/sources
$ ./configure
$ make
$ make install

Answer 21

This is what finally worked for me.

brew reinstall postgres

After running the above command you might need to run

brew postgresql-upgrade-database

to access your previous data.

Answer 22

Lots of answers around restoring the missing version of icu4c. I had this same error with postgresql and I imagine this can manifest with various programs that depend on dynamically linking that library.

For me, I'm using a specific version of postgresql, namely postgresql@12. I found the simplest fix was to reinstall that

brew reinstall postgresql@12

I imagine that would work for php as well.

Answer 23

On MacOS Mojave, only way I could fix it was with brew upgrade

Answer 24

Rather than install an old version of icu4c that the older (precompiled) php can link to, it's better to recompile the old php to link to the more recent library.

brew uninstall [email protected]
brew install --build-from-source [email protected]

This will build php and link it to the newer library. I found reinstall didn't quite work; the new install choked when the destination folder already existed.

I also did brew link --force [email protected] for my environment.

Answer 25

I had problems because my version of PHP (7.3) was expecting icu4c 63 and brew would only install 64.

https://stackoverflow.com/a/55828190/2000947 helped me install 63.

Answer 26

On OSX 10.15.4 running xcode-select --install fixed the issue for me.

Answer 27

The solution in this gist did it for me

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

Answer 28

Leland's answer worked for me, but I had to change steps 4 and 6 to:

4) git checkout -B icu4c-62.1 575eb4b

6) brew reinstall Formula/icu4c.rb

Answer 29

In my case, brew update icu4c to version 67.1 so my php7.1 doesn't work. Just reinstall icu4c, then it fine.

Ref this: https://devhoi.com/threads/error-dyld-library-not-loaded-usr-local-opt-icu4c-lib-libicui18n-64-dylib-with-php7-1.26/

Answer 30

[2022 Build It Yourself Edition]

Works for me on Mac OS 11.6.8 Big Sur.

$ wget https://github.com/unicode-org/icu/releases/download/release-69-1/icu4c-69_1-src.tgz
$ # In Finder, copy from Downloads/ to your home directory
$ tar xzvf icu4c-69_1-src.tgz
$ cd icu/source
$ ./configure
$ make
$ make install

After that, node and npm worked again.
