Can this be of help https://github.com/electron/electron/issues/3708

ALso

--ignore=node_modules/electron-*

shouldn't that be a regexp?

@englishextra Unlikely, it appears he's using a pretty old version of electron-prebuilt, not the electron NPM package.

@TracyGJG there are a few things that are inconsistent in your example:

• You're using Electron 0.25.2, which does not have support for the electron module (that was added in 0.35.0, but you should use the newest Electron release if possible).
• When you run npm start, you're running main.js, but when you run the packaged app, you're running index.js because Electron runs the script in the main section of package.json (see Electron docs)
• Your ignore flag is incorrect (it is a regular expression, not a glob expression, see the API docs) and unnecessary because by default, Electron Packager removes all packages in devDependencies.

That being said, this doesn't appear to be an Electron Packager specific problem at this time. You may get better help from the greater Electron community.

@malept thanks for clarification. Also it seems some module has incompatible checking environment Js wrapper.

All working following the good advice received.
