Hello colleagues, I tried to install your lpwanserver product but I get errors when I run npm install in lpwa directory  
I would appreciate some help and a hint as to what I’m doing wrong

```auto
git clone https://github.com/cablelabs/lpwanserver.git
$ cd lpwanserver
$ npm install

```

output npm-debug.log

108315 error There is likely additional logging output above.

I use Ubuntu 16.04.6 LTS / npm -v 3.5.2 / nodejs -v v4.2.6

```auto
curl -sL https://deb.nodesource.com/setup_10.x | sudo bash 
$ sudo apt install nodejs

```

Hi @goldware. I believe this will be resolved if you update Node and NPM to versions at or higher than those specified in package.json. If you are on Mac or Unix, I like to use nvm to install Node.js and NPM.  
It makes it easy to switch between versions, but also helps in avoiding permissions errors on some npm installs.
