Question:
Start Cosmos-GUI

Description:
I want to install Cosmos.
I have installed Apache-Hadoop 2.6 with a single node and my next move was install cosmos-gui.

So I follow the official installation guide - https://github.com/telefonicaid/fiware-cosmos/blob/develop/cosmos-gui/README.md#installation but npm start command doesn't work.

Error:

fs.js:432
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
^
