sudo apt install curl
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
nodejs -v
v8.4.0

Install development tools to build native addons:

• Install Android
• Install Android SDK requirements

cd ~
mkdir android-sdk
cd android-sdk
wget https://dl.google.com/android/repository/sdk-tools-linux-3859397.zip
