In case your will get errors from node-gyp especially for Argon2 or webrtc

3.1 node-gyp on Windows

open a Command Prompt with Administrator rights

cd C:\Path\To\Node-WebDollar\
npm install --global --production windows-build-tools                                    
npm install

3.2 node-gyp on Linux

Installing Argon2 node.js

sudo apt install linuxbrew-wrapper 

In case your receive some errors, try sudo apt-get -f install

To check the version gcc --version In case the GCC is not installed, install gcc brew install gcc

sudo apt-get install clang
npm install -g node-gyp

gcc --version will help you to find the Version. It worked on gcc 5 and gcc 6

env CXX=g++-5 npm install
env CXX=g++-5 npm install argon2
