"WebIO jupyter extension must be installed using Conda" but the Conda doesn't works

Hi, everyone! I am new to use Julia and trying to use Plots/PyPlot for visualization. But it seemed to be needed to install WebIO for them, so I tried and got in trouble like

julia> WebIO.install_jupyter_nbextension()
ERROR: The WebIO Jupyter extension must be installed using Python or Conda. See https://juliagizmos.github.io/WebIO.jl/latest/providers/ijulia/ for more information.
 [1] error(s::String)
   @ Base .\error.jl:35
 [2] _error()

   @ WebIO C:\Users\me\.julia\packages\WebIO\rv35l\deps\jupyter.jl:10

   @ REPL[2]:1

Then, I tried to install it using Conda package, but it neither worked. The error code can be seen below

How can I solve this?
Im glad to get any ideas. Thank you:)

Are you trying to implement the WebIO through the VSCode? Because it is not supported there and it is not possible.
