Unable to run ipython-notebook 2.7 with jupyterhub

问题

I am trying to run ipython 2.7 notebooks with jupyterhub on Ubuntu 14.04 - but I haven't been able to figure out a way. Any suggestions?

I know one needs to add kernels in the file ~/.ipython/kernels.json I have the following in this file:

{
 "argv": ["python3", "-m", "IPython.kernel",
          "-f", "{connection_file}"],
 "display_name": "Python 3",
 "language": "python"
}
{
 "argv": ["python2.7", "-m", "IPython.kernel",
      "-f", "{connection_file}"],
 "display_name": "Python 2",
 "language": "python"
}   

回答1:

~/.ipython/kernels.json is not the right path. And theses files are not ment to be edited by hand. Also the file you have is not valid json, the server will be unable to read it if it was in the right place.

use python2.7 -m IPython kernelspec install-self and python3 -m IPython kernelspec install-self for IPython to put the right files in the right locations.

That being said, even with the kernels files wrong you shoudl be able to start jupyterhub. Do you have other error messages ?
