Cannot find jupyter executable.

my computer is windows 10. i use pip to install jupyter

Solution

  • The iracket install command needs to run the jupyter.exe command to find the directory where Jupyter kernels are stored. So you need to find where pip installed jupyter.exe and then add the directory containing jupyter.exe to your PATH, or you need to run the iracket install script with raco iracket install --jupypter-exe path-to-jupyter.exe.
