Error on Windwos npm installation

Hey, great project first of all. But installing on a Windows system with Node.js v 8.11.2 I get an error when I want to compile relaxed document.

`relaxed my_document.pug Launching ReLaXed…

Now waiting for changes in my_document.pug and its directory events.js:183 throw er; // Unhandled ‘error’ event ^

Error: watch C:\Users\kwoxer\Anwendungsdaten EPERM at _errnoException (util.js:992:11) at FSWatcher.start (fs.js:1382:19) at Object.fs.watch (fs.js:1408:11) at createFsWatchInstance (C:\Users\kwoxer\AppData\Roaming\npm\node_modules\relaxedjs\node_modules\chokidar\lib\nodefs-handler.js:37:15) at setFsWatchListener (C:\Users\kwoxer\AppData\Roaming\npm\node_modules\relaxedjs\node_modules\chokidar\lib\nodefs-handler.js:80:15) at FSWatcher.NodeFsHandler._watchWithNodeFs (C:\Users\kwoxer\AppData\Roaming\npm\node_modules\relaxedjs\node_modules\chokidar\lib\nodefs-handler.js:229:14) at FSWatcher.NodeFsHandler._handleDir (C:\Users\kwoxer\AppData\Roaming\npm\node_modules\relaxedjs\node_modules\chokidar\lib\nodefs-handler.js:408:19) at FSWatcher.<anonymous> (C:\Users\kwoxer\AppData\Roaming\npm\node_modules\relaxedjs\node_modules\chokidar\lib\nodefs-handler.js:456:19) at FSWatcher.<anonymous> (C:\Users\kwoxer\AppData\Roaming\npm\node_modules\relaxedjs\node_modules\chokidar\lib\nodefs-handler.js:461:16) at FSReqWrap.oncomplete (fs.js:153:5)`

How can I fix it? Is it because of the old Node.js Version?

Now it works when I download the needed files and running it in a folder on my Desktop. Thank you guys you helped me a lot.

it tells you that you need to NPM-install ReLaXed again.

It is just node-sass. He has to install windows-build-tools globally and then run npm rebuild node-sass --force.
