I can reproduce this. Actual loader output:

Version of libcairo-2.dll provided by sharp indeed is missing that function:

Versus the version of libcairo-2.dll provided by canvas:

I don't know why it's missing from the sharp version. They package a newer version (1.14) than canvas uses on Windows with the normal install instructions (1.10), but in any case that method has been around since Cairo 1.2.

Anyway, as far as I know, this is because when Windows searches for a DLL, if a DLL with the same module name is already loaded, that one will be used (see docs).

Is it viable to require canvas before sharp at least for now? A quick attempt to use DLL redirection with a canvas.node.local file didn't work, and libcairo-2.dll doesn't appear to contain a manifest to point to. Out of time right now to keep looking.

[SeanSobey]

Thanks for the further investigation, the error makes sense now that the function is missing on the other lib.

I have found an additional compilation however, the above workaround causes issues on Linux:

Segmentation fault

npm ERR! Linux 3.13.0-112-generic
node v7.10.0
npm  v4.2.0
code ELIFECYCLE
errno 139
Exit status 139

The SegFault appears to be caused by loading canvas before sharp.

So my ammended workaround is the glorious:

if (process.platform === 'win32') {
	require('canvas');
	require('sharp');
} else {
	require('sharp');
	require('canvas');
}

(The OP issue does not present on Linux it appears).

Hello, thanks to your investigation we discovered this was a problem with libvips' Windows build. libvips/build-win64#13 will fix this for the next release, which will be available in a future sharp v0.19.x.

[SeanSobey]

Great! Thanks for the feedback.

[zbjornson]

Thanks @lovell !

It would still be nice to figure out how to get redirection working sometime so this can't happen in the first place.

[SeanSobey]

As of sharp 0.20.01 and canvas 2.0.0-alpha.11 this is still an issue.

[BE-CH]

For anyone wondering. Running sharp 0.28.1 and canvas 2.7.0 still has this issue.

[cloewen8]

Has anyone found a configuration of versions for node-canvas and sharp that does work? Oddly only started experiencing this issue recently, was it reintroduced?

I have a dependency that relies on the latest versions of these. Thinking of using npm shrinkwrap to downgrade these sub-dependencies in the meantime.

[lovell]

@cloewen8 I believe this problem only affects Windows users that still rely upon GTK2 (2011) for canvas but very happy to be updated/corrected if things have improved - see https://sharp.pixelplumbing.com/install#canvas-and-windows

[mctrafik]

Still an issue in 2022. sharp@0.31.1 and canvas@2.10.1

[m-s-morgan]

Is there any workaround for this? Still an issue with:

Node: 18.13.0
Sharp: 0.31.3
Canvas: 2.11.0

#2155

[ztomm]

My workaround for now is to import node-canvas at the very beginning of the project and send a blank canvas to nirvana. This lets node-canvas and sharp work as usual.

// my-startfile.js

const { createCanvas } = require('canvas')
createCanvas(0, 0)

// ...

// somewhere else ...

const sharp = require('sharp');

When the fix comes sometime, this can simply be deleted again.

[woxman]

Is there any workaround for this? Still an issue with:

Node: 18.13.0 Sharp: 0.31.3 Canvas: 2.11.0

you can fix this problem??

[woxman]

Were you able to solve this problem??
please help me....

Appears to play well with Sharp 0.32.5, no workarounds.
