Electron fails due to "permission denied"

[lidel]

Hello,

Installation with npm v5.3.0 yields this warning:

> npm install --dev                                                                                                                                                                                                      130 ~/tmp/telescope master
npm WARN install Usage of the `--dev` option is deprecated. Use `--only=dev` instead.
(...)

When I try to start it, it fails due to permission error:

> ./node_modules/.bin/electron-forge start                                                                                                                                                                                  ~/tmp/telescope ?master

it is due to odd permissions in ~/.config/Electron/extensions/fmkadmapgofadopljbjfkapdkoienihi/build/:

Am I missing something or are installation instructions not up-to-date?

I tested on node v8.5.0 and npm v5.3.0

I am unable to replicate what @lidel is experiencing in node v7.4.0, npm v4.0.5, and 9326e33.

$ npm install --dev

Alright, it was on my end then.
Running via sudo is a bad practice, so I fixed it by chmod -R 777 /home/lidel/.config/Electron/extensions/fmkadmapgofadopljbjfkapdkoienihi/build
