Answer 1

You are running a much-too-old version of node and npm. You have node v0.5 which is very out of date. Upgrade to node v0.10 and things will work.

Modern node.js versions for Ubuntu are available via this PPA from Chris Lea

To install:

sudo apt-get install python-software-properties
sudo add-apt-repository --yes ppa:chris-lea/node.js
sudo apt-get install nodejs

UPDATE

It looks like your old version of node is installed at /usr/local/bin/node. The new version from the Chris Lea PPA will be at /usr/bin/node. So to verify all is well, do:

/usr/bin/npm --version #Should be approx 1.2
/usr/bin/node --version #should be approx v0.10
/usr/bin/npm install -g express

You should uninstall the local node, or fix your PATH:

export PATH=/usr/bin:$PATH
