How to run jupyterhub using sudo. Error: commad not found

Question

I want to run Jupyterhub on my server. I installed Jupyterhub from the instruction. I try it from both my computer and the server where both running on Ubuntu 16.04. When I start Jupyterhub without sudo, everything is Ok on my computer, and I can log in with my user and It starts the jupyter server. But when I run jupyterhub from the server after login I get error 500: Internal server error and it seems its because of permission error

PermissionError: [Errno 13] Permission denied

Then I tried to run jupyterhub using sudo: sudo jupyterhub -f jc.py where jc.py is my configuration file. And I see this error:

sudo: jupyterhub: command not found

At first step, I don't know why sudo doesn't recognize jupyterhub command, As the guide says, I install jupyterhub using conda.

To solve that problem I run jupyterhub from the path:

sudo anaconda3/bin/jupyterhub -f jc.py and this time I get this error:

FileNotFoundError: [Errno 2] No such file or directory: 'configurable-http-proxy'

And absolutely I'm sure that I installed 'configurable-http-proxy' when I run conda install -c conda-forge jupyterhub # installs jupyterhub and proxy.

Why sudo doesn't recognize jupyterhub? How can I solve that PermissionError?

Answer 1

Please specify the path at which configurable-http-proxy is installed by conda. Find path from shell using command
sudo which configurable-http-proxy

Make sure that this path is added to PATH variable of root user. Check using
sudo echo $PATH

If not please add it to PATH and try again.
