The specified module could not be found, with electron v4.0.0.

[iacovlev-pavel]

With electron 3.0.12 everything seems to work fine.
Changed version to 4.0.0, removed node_modules, did npm i, all ok.

If I run electron-rebuild, the command runs, but it does not rebuild the sharp module, does not seem it's picking it up.
If I run require('sharp') I get:
The specified module could not be found

If I cd to node_modules/sharp and try to recompile it manually:
node-gyp rebuild --target=4.0.0 --arch=x64 --dist-url=https://atom.io/download/electron
and try require('sharp') I still get The specified module could not be found.

Note: I have checked and sharp.node is present at the specified path.

[lovell]

The target flag passed to node-gyp refers to the version of Node rather than the version of Electron.

You'll probably want to use electron-rebuild.

[iacovlev-pavel]

electron-rebuild is what I am currently using with Electron 3, but it fails with Electron 4.
And by fail I mean it does nothing, it just skips the sharp package, that's why I tried manually with node-gyp.

From what I understand the version is for electron since dist-url is set to https://atom.io/download/electron

[lovell]

Is this on Windows? If so, try pointing Dependency Walker at the sharp.node file to help determine which shared library might be causing the problem.

[ddding]

sharp.zip
I have the same issue and here is my Dependency Walker file.

[lovell]

Thanks, according to that .dwi file the missing shared library is node.dll so I guess either something changed in the way Electron 4 provides/packages this and/or electron-rebuild does not yet support it.

I'd imagine other native modules are going to fail in a similar manner - please can you report this downstream.

[lovell]

"However, in Electron 4.x and higher, the symbols needed by native modules are exported by electron.exe, and there is no node.dll in Electron 4.x."

https://electronjs.org/docs/tutorial/using-native-node-modules#troubleshooting

[ddding]

Thank you, but I still don't understand how to make things right, or maybe I should just wait for electron-rebuild to release some update?

[lovell]

Please can someone confirm that this problem is limited to Windows only. Is anyone able to produce a minimal repo that exhibits the problem?

[groboter]

I have placed a very simple repo which exhibits the problem here https://github.com/groboter/sharpErrorTestApp. I hope it is ok, because it is my first one!

Basically it is just the Quick-Start-App from https://github.com/electron/electron-quick-start and I just added line 3 const {sharp} = require('sharp') which produces the error.

[lovell]

The version of Node in Electron 3 does not appear to maintain ABI compatibility with the version in Electron 4 despite both claiming to provide ABI version 64.

When you run electron-rebuild it calls prebuild-install, which correctly reports that it has a prebuilt binary for Electron with Node ABI version 64. However this binary fails with Electron 4 due to a change in Node ABI without a corresponding version increment.

You can hack your way around this by removing prebuild-install before running electron-rebuild.

npm install
rm -rf node_modules/prebuild-install
./node_modules/.bin/electron-rebuild

In summary, Electron needs to sort out its ABI versioning.

[lovell]

Here's confirmation of the Electron 3 vs 4 ABI incompatibility - electron/node-abi#55 (comment) - this will impact all native modules that provide prebuilt binaries for Electron.

[iacovlev-pavel]

@lovell Thank you for clarification and for such an awesome library in general.

electron/electron#16687 Am I correct that this should fix the issue?
But I am still getting an error when building with electron-builder on mac.

This is probably an electron-builder issue and not a sharp one.

@midevnull electron-userland/electron-builder#3660

[xland]

Electron 4.1.0 seems to have solved this issue, is it?

Electron 4.1.0 was released to work around issues users were experiencing with node-pre-gyp based native modules and our ABI number in Electron >= 4.0.4.

Fixed a crash when calling ECDH.setPrivateKey(). #17297
TouchBarSegmentedControl instances now correctly update when you update the segments array and remove label or image dynamically. #17335
https://electronjs.org/releases/stable#4.1.0

[tomaschyly]

I tried just Electron v4.1.0, but in my case it did not help. Gonna have to wait for sharp update.

[mceachen]

I tried just Electron v4.1.0, but in my case it did not help. Gonna have to wait for sharp update.

@tomaschyly: Did you clean your build machine? I had to not only delete my project's node_modules, but

rm -rf ~/.electron ~/.electron-gyp ~/.npm/_libvips* ~/.node-gyp ~/.cache/yarn/*/*sharp*

(I added it as postinstall script)

[tomaschyly]

Yes I did try to clean everything, but it seems that I will have to wait for update like I have been told here #1608

[lovell]

The ABI version of 69 used by Electron 4 is (correctly) considered "oddball" by the prebuild infrastructure so this is still blocked until the approach proposed in prebuild/prebuild-ci#11 is addressed.

[JakeRadMSFT]

What is the workaround for this? Using Electron 3?

[xland]

@JakeRadMSFT

Yes, I have rolled back to Electron 3.1.6(The last version of 3.x.x)

[JakeRadMSFT]

@xland have you gotten it to work after packaging it?

With 3.1.6, I'm hitting this issue: #1519.

[xland]

@JakeRadMSFT
Electron 3.1.6 and sharp 0.21.3 work well together on macOS, Win10 and Ubuntu

https://github.com/xland/xiangxuema

[inukshuk]

I think everything already works with Electron 4.1.

I originally run into this same issue, but then I realized that npm update --depth 9999 did not update sharp's sub-dependencies and I was stuck on older versions of prebuild-install and node-abi. Having updated those and also node-gyp globally sharp 0.21.3 works for me on Electron 4.1.

I'm having unrelated issues with 0.22 / libvips 8.7.4 on Ubuntu Xenial (because of older versions of librsvg or cairo, not sure yet) but on newer Linux systems I had that combination working as well.

[JakeRadMSFT]

Fixed my issue on Mac (Mac works with Electron 4.1). See #1519

One windows, I still get "Error: The specified module could not be found".

Now trying a downgrade to 3.1.6.

Update:

Doesn't work with 3.1.6. Perhaps I'm hitting some other issue?

[JakeRadMSFT]

Sigh ... it's because of this: mapbox/node-pre-gyp#278

soon to be fixed: mapbox/node-pre-gyp#279

[lovell]

Should anyone want to speed all this along, the best thing to do would be to work on prebuild/prebuild-ci#11 and ensure ABI version 69 is added to the "oddball" list. Without this a prebuilt sharp will not be available for Electron 4 / ABI 69.

[JakeRadMSFT]

That's actually not the issue anymore ... I think it works against 4. I'll open a new bug ...

[barakman]

Encountered a similar issue with web3 and electron.

Posted an MVP at electron/electron-quick-start#269.

[lovell]

I've opened a PR to help ensure prebuilt binaries for the latest Electron 4 / ABI 69 will soon be available - see prebuild/prebuild-ci#16

[lovell]

v0.22.1 now available with prebuilt binaries for Electron 4 and 5.

Please remember to run electron-rebuild (which may itself also need updating to pick up the new ABI versions),

[xland]

This issue occur on electron 6.0.1.
