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

On some Windows systems you may not succeed even if you run R from cmd / powershell. That's the case on my machine. My workaround is to run R from Anaconda Prompt (if you installed Jupyter via Anaconda). You may need to specify the full path if R is not on your PATH.

I think this is some problem related to the PATH, however I had no luck adding Anaconda\Lib\site-packages\jupyter_client to my system PATH.
