Unable to install on Ubuntu 14.04

Hi,

I am facing on this error on Ubuntu 14.04

This is error when I was trying to use bootstrap.py

Upgrading TLJH installer...
Traceback (most recent call last):
  File "bootstrap.py", line 83, in <module>
    main()
  File "bootstrap.py", line 68, in main
    ] + pip_flags + [tljh_repo_path], stderr=subprocess.STDOUT)
  File "/usr/lib/python3.4/subprocess.py", line 620, in check_output
    raise CalledProcessError(retcode, process.args, output=output)
subprocess.CalledProcessError: Command '['/opt/tljh/hub/bin/pip', 'install', '--upgrade', 'git+https://github.com/jupyterhub/the-littlest-jupyterhub.git']' returned non-zero exit status 1

This is something when I was trying to run setup.py

sudo /opt/tljh/hub/bin/python3.4 setup.py install

Error message error in the-littlest-jupyterhub setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers

This is a little bit strange to me. Do you guys have any idea?

Thank you, Tran

Why not put it in an important directive?
