Hi  
I am trying to replicate the interactive plots examples using Interact.jl package ([Tutorial · Interact](https://juliagizmos.github.io/Interact.jl/stable/tutorial/)) on a Jupiter notebook. But running into problem with detecting WebIO. This is the first time I had to use WebIO on my machine (Mac). Here is what I tried.

`using Interact, Plots, Mux

WebIO.webio\_serve(page(“/”, req → ui), rand(8000:9000)) # serve on a random port  
`  
The error message says:

> The WebIO Jupyter extension was not detected. See the [WebIO Jupyter integration documentation](https://juliagizmos.github.io/WebIO.jl/latest/providers/ijulia/) for more information.

Following the link given for more information ([IJulia (Jupyter) · WebIO](https://juliagizmos.github.io/WebIO.jl/latest/providers/ijulia/)), I have installing WebIO using the terminal command, restarted the Jupiter notebook kernel, re-ran the code. I am still getting the same error.  
Any help is appreciated.

Are you doing this in a clean environment? Otherwise, what are the contents of the your environment?

The output for the following might be helpful:

```julia
using Pkg
pkg"status -m"

```

I didn’t understand what is meant by “clean environment”, could you explain this?  
The output from

```julia
using Pkg
pkg"status -m"

```

gives a long list of packages, Below I give them . What should not be in that list?

Try

```julia
using Pkg
pkg"activate --temp"
pkg"add IJulia Interact Plots Mux WebIO"
using Interact, Plots, Mux

WebIO.webio_serve(page(“/”, req → ui), rand(8000:9000)) # serve on a random port

I noticed that when you update IJulia or WebIO, you should after re-build them:

pkg\> build WebIO  
pkg\> build IJulia

Then the error message won’t appear anymore.
