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.

I had to delete installed programs and compile latest versions of both from source. For Python compiling I had to use this configuration https://github.com/sloria/TextBlob/issues/173
