Compatible with Julia 1.x? ("Unsatisfiable requirements detected for package WebSockets")

[gubikmic]

Following the example in the Readme the following error occurs:

(v1.1) pkg> add Mux WebIO Interact Widgets UnicodePlots CSV DataFrames

Is there any straightforward fix to this?

[piever]

Looks like you are fixing HTTP to version 0.8 which is not yet compatible with WebSockets, you can either:

(v1.1) pkg> free HTTP

Or use the environment provided by this repository (you may need to pull to get latest master, as I've just updated it). For that just start the REPL inside InteractDemos folder and:

(v1.1) pkg> activate .

(InteractDemos) pkg> instantiate

Hey, thanks for your reply (and sorry my late answer).

This gets me one step further and I can launch and connect to the local webserver but there's still an error when I try to run the examples.

I'll give the full prompts below just to make sure I'm not missing anything:

$ git pull  # or git clone https://github.com/piever/InteractDemos.git and cd into that directory
$ julia
(v1.1) pkg> add Mux WebIO Interact Widgets UnicodePlots CSV DataFrames
(v1.1) pkg> activate .
(InteractDemos) pkg> instantiate
julia> include("main.jl")

Then I connect to localhost:8000 and click on the slider example and the following crash occurs:

If you get around to it, it would be nice if you could see if you get the same error. Thanks.

[piever]

Does the interface keep working despite the error in the console or it stops responding?

[piever]

I've updated to the latest Mux plus WebSockets and it does seem like there are some WebSockets error happening that break interactivity, I'll see if there is a way to make things more robust.

[gubikmic]

It works now
