I followed this link for installing the R kernel in Jupyter Lab. However, when I got to the last step for macbook, I received this error:
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) : error in running command
I tried to re-install Anaconda again, but this did not help.
