jupyter-client has to be installed but “jupyter kernelspec --version” exited with code 127

Question

I have already installed Jupyter notebook in my ubuntu 16.04 machine. In jupyter notebook there is by default python installed. Now I want to use R from jupyter notebook.

Answer 1

I had the same error but the fix was different:

Make sure you also have anaconda install on your system! (or at least jupyter) https://conda.io/docs/user-guide/install/index.html
