Don't forget to publish 'discipl-core-baseconnector' as npm package to prevent this error from happening.

steven@steven-K501LX:~/Code/discipl-core-uport$ npm update

npm ERR! code E404
npm ERR! 404 Not found : discipl-core-baseconnector
npm ERR! 404 
npm ERR! 404  'discipl-core-baseconnector' is not in the npm registry.
npm ERR! 404 You should bug the author to publish it (or use the name yourself!)
npm ERR! 404 
npm ERR! 404 Note that you can also install from a

Where the dsicipl-core-baseconnector isn't published yet, we need to define dependencies with proper git source(s).

Add to the package.json file:


"dependencies": {
    "discipl-core-baseconnector": "git+https://github.com/discipl/discipl-core-baseconnector.git"
  }

With an error such as: Error: Cannot find module 'uport-connect'

steven@steven-K501LX:~/Code/discipl-core-uport$ npm i --save uport-connect

    About the error: setuptools do not appear to be installed. Follow the Installation Instructions from the PyPI website.

  4. The libsodium package will have to be installed manually. (note the error!)

    Sounds like How To Install the Django Web Framework on Ubuntu 14.04 from Digital Ocean is a better option to follow installing python.
