NPM: The “ld: library not found for -lgcc_s.10.5”

Question

When I use npm install to install dependencies of this repository, I encountered an error like this:

> fsevents@0.3.8 install /Users/hanfeisun/Workspace/vue-webpack-example/node_modules/webpack/node_modules/watchpack/node_modules/chokidar/node_modules/fsevents
> node-gyp rebuild

  SOLINK_MODULE(target) Release/.node
ld: library not found for -lgcc_s.10.5

gyp ERR! not ok 
npm WARN optional dep failed, continuing fsevents@0.3.8

However, the installation is still finished successfully. And when I use npm run, the app still works well. Does anyone have ideas about what node-gyp rebuild does here? And why the project works well even node-gyp throws error here?

Answer 1

I ran into this problem after upgrading to Node 4.1.0 (OS X 10.10.5) and didn't have any luck after reinstalling from the official package. For what it's worth, this solved it for me:

cd /usr/local/lib
sudo ln -s ../../lib/libSystem.B.dylib libgcc_s.10.5.dylib

(Originally found here.)

Answer 2

I also had this problem. Turns out I had upgraded Xcode but never rebooted. After reboot I was able to npm install successfully.

Answer 3

It is solved after I reinstalled node.js from the official pkg.
