Unable to start kernal

[Abhishek-sopho]

I'm getting following errors while running iruby notebook. The kernel doesn't seem to start and gives following errors:

[I 01:16:07.580 NotebookApp] Kernel started: 359b3824-4323-4ee4-b46e-c790146807ac

This looks like an issue with your Ruby installation. What platform are you on? How did you instal ruby? What is the output of iruby --version?

I'm using rvm to manage my ruby installation and I faced the same issue, but only when I'm running jupyter via anaconda navigator started with following .desktop shortcut

#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Type=Application
Name=Anaconda-Navigator
GenericName=Anaconda
Comment=Scientific Python Development Environment - Python3
Exec=bash -c 'export PATH="/home/vladimir/anaconda3/bin:$PATH" && /home/vladimir/anaconda3/bin/anaconda-navigator'
Categories=Development;Science;IDE;Qt;Education;
Icon=/home/vladimir/anaconda3/lib/python3.7/site-packages/anaconda_navigator/static/images/anaconda-icon-256x256.png
Terminal=false

MimeType=text/x-python;

I've tried to run start navigator in terminal with command bash -c 'export PATH="/home/vladimir/anaconda3/bin:$PATH" && /home/vladimir/anaconda3/bin/anaconda-navigator' and everything worked fine. So I tried to add --login -i options into .desktop file, and it fixed the problem, but only when this file is placed in my home directory.

Hope it will help you if you're starting anaconda using one of solutions provided here.
