Hi @fbaldo31, sorry for the late answer. The source of problem is that the plugin itself is interpreting as a native module and is trying to use Electron Rebuild on one of its loaders. I will try to reproduce this strange behavior with your configuration and reply as soon as possible. I am also going to prepare a simple working "Hello, world" example, too.

Hi @fbaldo31 as I have promised I have prepared a quick sample which can be found at https://github.com/evonox/electron-native-plugin-samples/tree/master/hello-world

I am having a similar issue but with sqlite3

Have tried several different configurations but can't seem to get this right. No matter what I do it appears the rebuild is looking for a node_modules dir that isn't there

Hi @stowns, thanks for reporting the issue. I would ask you for some more information:

1. What platform are you using? (For me to prepare as much compatible environment as possible).
2. What version of ElectronNativePlugin are you using? The latest is 0.3.
3. Currently I think the ElectronNativePlugin does not run when using devserver. Could you please try to build a release prototype in Electron? Or just tell me if you are trying to run it through devserver...

[evonox]

Dear @fbaldo31 , @stowns I very apologize for not answering for long time. I have bad news in the sense that I am very busy with a different project for now. I have a request for a person who might be willing to take over the ElectronNativePlugin to continue its development. If you know about someone who might continue the development of this plugin, then I am ready to transfer the ownership of this project.
