So I wanted to set up R kernel for Jupyter in VSCode, I installed Jupyter via pip, in the R console I typed:

install.packages('IRkernel')

and the package was successfully installed, then I tried to run the command

IRkernel::installspec(user = FALSE)

or

IRkernel::installspec()

but I get following error: jupyter-client has to be installed but “jupyter kernelspec --version” exited with code 1. What should I do to fix it?
