MacOS w/ node-canvas, Library not loaded: /usr/local/opt/pixman/lib/libpixman-1.0.dylib

See original GitHub issue

electron-builder v 22.3.2

Uses node-canvas. Building for Windows and Linux appears to work properly, however with MacOS I get the following error when I try to run it on a fresh machine. Installing brew and installing the cairo build dependencies on the fresh machine allowed it to run.

@nullxx thank you so much for your solution! It did fix my build issues on Windows, but not on MacOS. The compiled canvas.node still seemed to reference .dylib files in my /usr/ directory, and not the ones copied/packaged. (My debugging process involved a lot of otool -L canvas.node and install_name_tool -change if anyone’s interested)

My final approach:

Copied the required .dylibs as described by you (to /node_modules/canvas/lib/dylib)
Used your bindings.gyp file to run node-gyp rebuild inside node_modules/canvas (which calls node-gyp configure anyway)
Set buildDependenciesFromSource, nodeGypRebuild, npmRebuild all to **false**, as they seem to rebuild the library unneccesarily, breaking the references again
Ran npx electron-rebuild -f -w canvas, which I later added to the package.json
Patched build/Release/canvas.node with macpack (possible alternative: macdylibbundler)
Ran electron-builder --mac to get a .dmg that functions on a fresh machine without cairo, pango etc. installed.

Thanks again for your solution, I probably wouldn’t have figured it out alone!

@aWalrus try this solution:

Get the prebuilt libraries and copy them to the following paths:

node_modules/canvas/lib/dylib/libcairo-gobject.2.dylib

Change your node_modules/canvas/binding.gyp:

Run node-gyp configure inside node_modules/canvas
Run node-gyp rebuild inside node_modules/canvas
Add this config to your package.json

"build": "npx electron-rebuild -m ./node_modules/canvas"

Is better to remove the dependency from node_modules and move it to somewhere more stable folder.
