Try downgrade your Node.js, I'm using recommended version 6.x.x

[nitank]

same issue with v6.0.0 and v6.9.5

[didinj]

After the downgrade, make sure you have to remove node_modules and run npm-install again.

[nitank]

Even i cloned again after downgrade 2 times with fresh npm install.

ng build --env=prod --output-hashing none
got the fix from this thread.
willsoto/ng-chartist#94

for the EADDRINUSE :::4000
close down all terminals and reset your network interface to free up port 4000

npm install [email protected]

Did the trick for me
