Cannot find module 'xxxxxx'

[doowb]

Versions:

• Electron 0.36.5
• node 5.1.1
• OSX 10.9.5 x64

I started off with the example app and was able to open a file and require in a module like jquery inside the renderer process fine.

I want to dynamically create my html files, so I start an express server in the main process and request the files through .loadURL('http://localhost:8080');.

This serves up the file, but then I started getting the Cannot find module 'jquery' error. I tried some of the other suggested and even tried another module from my node_modules but nothing was working.

I was able to use protocol.interceptStringProtocol('file', handler) to proxy file:// requests through to the server and that was working when I ran the project locally by doing electron ..

Once I package up the project and try to run the app, I'm getting the Cannot find module 'jquery' error again. I've verified the node_modules exist in Contents/Resources/app inside the package.

Below is a screen shot of the app devtools open with the error and the globalPaths output. I'm not sure how to debug this or where to look next.

If you installed jQuery from npm, you can just call require('jquery').

It's not just jquery and I did try require('jquery'). That's the second Cannot find module 'jquery' in the screenshot.

It's not finding anything I have in my node_modules.

I just noticed you were loading a remote page with http:// protocol, in this case require won't be able to find local modules because there is no way to know current file system's path from a http page.

Usually the community is a better place for this kind of questions.

Thanks, I didn't notice the slack community when I was looking for answers, I'll check that out.

@zcbenz what about adding the main process' search path to the renderer? If I do the following I can require('jquery') with no problems:

require('electron').remote.process.mainModule.paths.forEach(function(path) {
    require('module').globalPaths.push(path);
});

What would be the downside of doing this?

Hi @doowb have you solved this problem?

Today I've got the same error.

But the error only occurs on production build

Any suggestion will be helpful
