Ubuntu Jupyterhub: 500 POST Spawner failed to start [status=1]

I am trying to run jupyterhub for multiuser mode:

sudo jupyterhub

I am able to login successfully with the user I used to install jupyterhub. However, when I try to login with other users I get the following message:

500: Internal Server Error Spawner failed to start [status=1]

And in the terminal:

user@server:~$ sudo jupyterhub

I don't know if that would be the source of the problem, however, I have jupyterhub version: 0.7.0. I tried to update it to 0.8.0 using: 

sudo pip install -U jupyterhub

But, I got:

Requirement already up-to-date: ****

I tried so long to find a solution online; I failed though.

Would someone please help me with this issue?

Thanks :)

you might install jupyterhub from source and see this log：

"pkg_resources.DistributionNotFound: The 'jupyterhub==0.8.0.dev0' distribution was not found and is required by the application"

I met the same problem and... this is caused by installing the binary jupyterhub and donot install packages... after exec 

pip3 install -r dev-requiremetns.txt .

the log let us to do setup.py by "Running setup.py develop for jupyterhub" and then run python setup.py build and python setup.py install and then abort and the log let me to use pip install . and then run pip3 install ., and then the jupyterhub run normally.

commands below:

cd /path to git code/jupyterhub/
python setup.py build
python setup.py install
pip3 install .
