I have been using R/Python and Jupyter Lab/Notebook on Macbook. In my new job, I need to install and run these applications on Windows 10.
I have Python, pip, Jupyter, R4.1 & RStudio installed manually (not through Anaconda). I try to execute step 2/3: Making the kernel available to Jupyter based on installation guide. I got error message in R Console.
> IRkernel::installspec()
Error in IRkernel::installspec() :
jupyter-client has to be installed but “jupyter kernelspec --version” exited with code 127.
In addition: Warning message:
In system2("jupyter", c("kernelspec", "--version"), FALSE, FALSE) :
'"jupyter"' not found
Appreciate your advice.
Please check if jupyter is in your user/system path. A quick way to check is by running jupyter in the command line, you could use powershell commandline:
Get-Command jupyter
CommandType Name Version Source
----------- ---- ------- ------
Application jupyter.exe 0.0.0.0 C:\Users\youruser\AppData\Local\Programs\...
If it's not there, then you can add to your system/user path and check with new instance of commandline again.
