reactide: [Installation] npm install broken

Hi, I’m trying to install ReactIDE, but when I use npm install there’s an error :

$ npm install
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/chokidar/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})
npm WARN reactide@1.0.0 No repository field.

and :

$ npm start

> reactide@1.0.0 start /opt/reactide
> cross-env NODE_ENV=production electron .
