I have executed the following command in Ubuntu 14.04 64-bit.
sudo apt-get update
sudo apt-get install nodejs modejs-legacy npm
I have the versions
npm -v
1.3.10
nodejs -v
v0.10.25
These are older than the recommended versions for AngularJS 2.
Why does apt-get download old version? How do I update to newer versions?
Debian/Ubuntu has old version in their package manager, you have to use custom PPA repository as stated here:
Setup it with:
curl -sL https://deb.nodesource.com/setup_5.x | sudo -E bash -
Then install with Ubuntu:
sudo apt-get install --yes nodejs
