ENOSPC: no space left on device when building mac dmg

[nunziotocci]

• Version: 7.12.2

• Target: dmg

When I run npm dist on my project on OS X 10.11 El Capitan, electron-builder outputs this:

$ npm run dist

> @ dist /Users/nunzio/Repos/postage/postage_electron
> build

Rebuilding app dependencies for arch x64 to /Users/nunzio/Repos/postage/postage_electron/app

Packaging for platform darwin x64 using electron 1.4.3 to dist/mac

Warning: App is not signed: CSC_LINK is not specified, and no valid identity in the keychain, see https://github.com/electron-userland/electron-builder/wiki/Code-Signing
Must be "Developer ID Application:" or custom non-Apple code signing certificate
Creating DMG
Warning: dmg.title is not supported, file issue if need
Creating MacOS zip

Then waits a minute or so, then spews out a bunch of messages of the form:

Error: ENOSPC: no space left on device, open '/Volumes/Postage 3.0.0-RC2/.VolumeIcon.icns/node_modules/plist/.jshintrc',

It was working with 7.10.2 with an explicit path on build.dmg.contents[1]

When I upgraded to 7.12.2, I got an error, "Cannot read proprty 'x' of undefined", this lead me to #799, so I removed the explicit path on build.dmg.contents[1]

Then I got this error.

It is worth noting that I embed a binary inside the app with a bunch of html:

$ du -hs app/postage/*
8.0K    app/postage/config          <<<<< this is the default config
2.3M    app/postage/postage         <<<<< this is the binary
 13M    app/postage/web_root        <<<<< this is the html/js

The repo is at workflowproducts/postage under postage_electron/

To reproduce:
clone, and go into the resulting repo:

$ ./configure && make all
$ cd postage_electron
$ ./update.sh
$ npm run dist

Do not specify "icon": "" in your package.json.

[develar]

Checks added, case "Cannot read proprty 'x' of undefined". Thanks a lot for project.

[nunziotocci]

That worked, but my app icon is not suitable to be the dmg icon, so I changed it to "icon": null for now.

Thank you for your quick response.

[develar]

JFYI: Setting to null is valid and supported way.
