How to require it in node module syntax

[j-f1]

Does he Node module syntax not work for you?

[yanlinsun]

No.
It says 'Module did not self-register' if I use node module syntax.
My node version is 10.15.3
Electron version 6.0.3

It says 'Module did not self-register' if I use node module syntax.

@yanlinsun I believe this is a different error, and I wrote some notes about understanding the issue over in atom/node-keytar#215 (comment) because I think your setup is leading to the wrong version being chosen by prebuild.

[yanlinsun]

@shiftkey I tried the electron-rebuild but no luck. I even tried different registry-js versions, not working.
Actually, the node module requires syntax does working if I run 'renderer.js' with node. But it seems not working with electron.
I test using electron-quick-start project and registry-js only, I have attached the project. Also, there are logs of installing registry-js. Would you take a look? Thanks.

This is unsurprising, because of mismatches between Node and Electron that aren't being handled correctly.

From the registry-js-1.8.0-install.log file, here's the failure fo 1.8.0:

prebuild-install info begin Prebuild-install version 5.3.0
prebuild-install info looking for cached prebuild @ C:\Users\ysun\AppData\Roaming\npm-cache\_prebuilds\e4858a-registry-js-v1.8.0-node-v64-win32-x64.tar.gz

prebuild-install WARN install Module did not self-register.

Notice how this is choosing registry-js-v1.8.0-node-v64-win32-x64.tar.gz - that's not the right file at all. The rest of the log is it trying to build the native module against node 10.15.3 which I guess is the version you have installed currently.

It's not clear to me how that you're using electron-rebuild correctly - it needs to be run after installing any packages but before you launch the app. I think that's the missing part here.

Failed attempts 1

I did run electron-rebuild right after I install registry-js, then run npm start.

$ ./node_modules/.bin/electron-rebuild -f -v 6.0.3 -w registry-js
- Searching dependency tree
√ Rebuild Complete

But the error is still the same. I notice that the files in node_modules/registry-js does not change at all after I run the electron-rebuild. I tried to run using electron-rebuild.cmd, not work either.

Failed attempts 2

I tried to rename the registry-js-v1.8.0-electron-v73-win32-x64.tar.gz to registry-js-v1.8.0-electron-v64-win32-x64.tar.gz. Then copy it into npm-cache/_prebuilds folder and re-install registry-js in electron-quick-start project again. I am trying to fool the npm to use v73 instead of v64 and the "fool" is working according to the log. However, this does not solve the problem. I notice there is a warning message in the log.

Working version

After some tweak, I managed to get a working version. This is what I did.

1. clone registry-js from github
2. npm run electron-prebuild
3. cp build/Release/registry.node ../electron-quick-start/node_modules/registry-js/build/Release
   Then it finally worked in electron.

Update

The above only works in the electron-quick-start project, not working in my other project. I am working on it.
My other project works as well after I run npm update. I think some part of the electron gets updated, as I can see some file changes in node_module/electron/dist folder, even the electron --version shows no difference after the update.

Conclusion

I believe this is because of the npm install compiles the registry.node against node, not electron. But how this happens I do not know. And the electron-rebuild seems not doing anything as the file in node_module/registry-js never touched. Is there any setting wrong in my environment?

[yanlinsun]

I find out that the electron-rebuild only work if I put 'registry-js' in "dependencies" section in package.json. It does not work if I put it under 'devDependenies' section.

Aha, this is helpful context. Thanks for digging into it @yanlinsun!

[yanlinsun]

I didn't use the electron-rebuild correctly. By default, it looks for productive dependencies and rebuilds.
To use electron-rebuild for devDependencies, use the following command:
./node_modules/.bin/electron-rebuild -t dev
