The main problem (for me and many others) is an outdated version of npm itself

$ npm version
{ http_parser: '1.0',
  node: '0.10.33',
  v8: '3.14.5.9',
  ares: '1.9.0-DEV',
  uv: '0.10.29',
  zlib: '1.2.3',
  modules: '11',
  openssl: '1.0.1j',
  npm: '1.4.28' }

The latest version of npm at the time of writing is 2.1.6, so 1.4.28 is deprecated. Just run

$ npm install npm -g
/home/ubuntu/.nvm/v0.10.33/bin/npm -> /home/ubuntu/.nvm/v0.10.33/lib/node_modules/npm/bin/npm-cli.js
npm@2.1.11 /home/ubuntu/.nvm/v0.10.33/lib/node_modules/npm

After that, npm install express works fine.

$ npm install express
