Installing node with brew fails on Mac OS Sierra

Question

I\'m trying to install node with homebrew on macOS Sierra. I run

 brew install node

After a seemingly successful install I get the following

Answer 1

Upgrading node fixed a problem.

brew upgrade node 

Answer 2

This was triggered for me after a brew upgrade and brew update ran. I was able to fix it by simply re-installing the two items flagged as problems (which made sense to me):

brew reinstall node
brew reinstall icu4c

Answer 3

For me it was apparently a problem with the icu4c installation from brew.

brew reinstall icu4c

will reinstall icu4c.

if you don't have it installed,

brew install icu4c

Answer 4

I had the same problem with my local php installation.

dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.62.dylib
  Referenced from: /usr/local/bin/php
  Reason: image not found
Abort trap: 6

Solved the problem with this command. (check your version)

brew link --overwrite --force php@7.1

Answer 5

This is the series of incantations that eventually worked for me based on this link suggested by @robertklep and @vovkasm.

brew uninstall --force node
brew uninstall icu4c && brew install icu4c
brew unlink icu4c && brew link icu4c --force
brew install node

I'm not sure if they're all needed, but given that I can't get my machine in the previous state... I'll just leave this info here, maybe it'll be useful for somebody else.

Answer 6

I recently encountered a similar issue (after doing brew switch node 9.8.0 to downgrade to a previous version of node)

dyld: Library not loaded: 
/usr/local/opt/icu4c/lib/libicui18n.60.dylib
  Referenced from: /usr/local/bin/node
  Reason: image not found
Abort trap: 6

The issue is that node is picky about which version of icu4c it's looking for, and the version I had installed (62) was higher than node was expecting.

To fix, I made sure I had version 60 of icu4c selected.

First I found which versions I had with brew info icu4c, then did brew switch icu4c 60.2 to select the one node was expecting.
