Make sure you have at least Node 6.9.1 installed, then try again.

Node Sass could not find a binding for your current environment: Linux 64-bit with Node.js 6.x

Found bindings for the following environments:

This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to build the binding for your current environment.

v6.9.1```


```tigger@Tigger:~/DotaBuddy$ nodejs --version
The program 'nodejs' is currently not installed. You can install it by typing:
sudo apt install nodejs```

I assume that means I dont have nodejs? yet i installed it using "nvm".

[waylaidwanderer]

The command is node not nodejs. Looks like you're on 6.9.1 now which is good. Try redownloading the project now that you've updated node, and rerun npm install.
