Sharp: Error: libvips-cpp.so.42: File not found with electron-builder under Linux

[NTag]

Hello,

I have a problem with Sharp and Electron under Ubuntu 16.10.

I just added sharp to my project, and in developement it works great, I can launch the app with electron . without any problem.

Then, I tried to package it for Linux, using https://github.com/electron-userland/electron-builder. The build process works, but when I try to execute the application with ./dist/linux-unpacked/test-sharp I have the following error:

A JavaScript error occurred in the main process
Uncaught Exception:

I tried to put sharp inside or outside the asar archive (like suggested in this issue), but the result is the same.
Especially, when I do: ldd dist/linux-unpacked/resources/app.asar.unpacked/node_modules/sharp/bin/linux-x64-53/sharp.node I get:

And under Mac and Windows I didn't have any problem...

I created a repository just to reproduce the error: https://github.com/NTag/test-sharp-electron

Thank you very much!

Hello, the appearance of /lib/x86_64-linux-gnu/libglib-2.0.so.0 suggests libvips might have been globally installed on the Linux box at build/install time. If so, please try removing it first.

Watch out for a node_modules/sharp/vendor directory created at install-time and make sure that ends up in the correct location relative to sharp.node (see @loader_path in binding.gyp#L142).

I have tried locate libvips I don't find anything global, so I guess libvips has not been installed globally?

I indeed have a node_modules/sharp/vendor folder in dev, and a dist/linux-unpacked/resources/app.asar.unpacked/node_modules/sharp/vendor/ after the build.

In dev, ldd node_modules/sharp/bin/linux-x64-53/sharp.node gives:

But in the electron-builder build, the sharp module is quiet different, that's strange...

[NTag]

Ok, I think I found the problem, which comes from electron-builder.

When it copies the files (which will go outside the asar archive), it doesn't consider symbolic links.

I created an issue here.

[lovell]

This looks like a feature of electron-builder so closing here as there's not a lot we can do, plus there seems to be a workaround.
