PlotlyJS Backend is not working under Juno/Atom 1.8.0 and julia 0.6.0

[BoundaryValueProblems]

Hello. I updated julia from v0.5.2 to v0.6.0 a few weeks ago. I'm using Plots v0.12.1 (the official released version). When I try to plot things with PlotlyJS Backend within a julia console under Juno/Atom editor, it doesn't work; nothing is plotted on the Plots Pane in the Juno/Atom editor. On the other hand, both GR and PyPlot Backends work without any issues. Here is the warning and error messages I get:

> using Plots
WARNING:
Error requiring Juno from Plots:
UndefVarError: PlotlyJSBackend not defined

Interestingly, if I do not use Juno/Atom editor, and simply run julia on a terminal, PlotlyJS Backend works without a problem. Is this a known problem? How can I resolve this issue? Any help would be highly appreciated.

Best regards, BVPs

Could you post Pkg.status()?

Yes, @mkborregaard, here is the output of Pkg.status():

Hm, I can't reproduce this with Plots and Atom on the latest releases.

[thatlittleboy]

I can confirm that the same error is occurring for me, on a freshly installed Julia v0.6.0, Windows 10, with Atom editor (v1.18.0) + Juno, after passing using Plots in the command prompt within the Juno/Atom interface.

[mkborregaard]

Do you still have this? None of us seem able to replicate, even with the same package profile.

[currymj]

I also have this problem, just discovered it now, on a fresh install of the release version of Julia 0.6, after nuking ~/.julia completely.

I'm going to try a fresh install of Atom as well.

(Problem remains after reinstalling Atom.)

@pfitzseb do you think this could be related to #916 ?

[pfitzseb]

Probably? Still can't reproduce this though. @currymj Can you try Pkg.checkout("Atom")?

[xiaoweiz]

I'm having the same problem on OSX with Julia 0.6 and Atom 1.18.0. Neither plotlyjs() nor plotly() works. But other backends including gr(), pyplot(), and pgfplots() work.

[mkborregaard]

And do you also get the error message immediately upon using Plots, or only after trying plotlyjs()? It is the first behaviour that's most mysterious.

[xiaoweiz]

Immediately upon using Plots in Atom. The error message appears in the console pane of the editor. It works perfectly in JupyterNotebook, though.

[mkborregaard]

Could you try to check out Plots "before916" and "after916" branches and see if you can replicate?

[mkborregaard]

No, before doing that, try to check out "mkborregaard/fix-993". It just might work.

[xiaoweiz]

How can I checkout a branch? I tried Pkg.checkout("Plots", "after916"), Pkg.checkout("Plots", "before916"), and Pkg.checkout("mkborregaard/fix-993"). All fail.

[thatlittleboy]

@xiaoweiz Try those after checking out the master version, i.e. Pkg.checkout("Plots"). It works for me.

@mkborregaard Some updates:

I tried with Pkg.checkout("Plots","before916") and got this after using Plots:

With Pkg.checkout("Plots","after916"), I got the reported warning:

With Pkg.checkout("Plots","mkborregaard/fix-993") I still get the reported error:

WARNING: Error requiring Juno from Plots:
UndefVarError: PlotlyJSBackend not defined

---

With Pkg.checkout("Plots") (i.e. master version) I get no error after using Plots.

[xiaoweiz]

I confirm simply checking out the current master version (Pkg.checkout("Plots")) solves the problem.

[mkborregaard]

Hm, sounds like an issue with Pkg caching. @BoundaryValueProblems does checking out master solve your problem too?

[BoundaryValueProblems]

@mkborregaard, yes, I just ran Pkg.checkout("Plots"), and PlotlyJS backend is now working! Thanks a lot everyone for your help! I hope that this change will be included in the next official release of Plots.jl.

[ChrisRackauckas]

I'm seeing this on release as well, but fixed on master. We may want to tag master sooner rather than later since this effects newcomers on their first plots.

[mkborregaard]

The only difference between release 0.12.1 and master is that precompilation is allowed on master. The metadata maintainer will not allow us to have active precompilation on releases for principal reasons, but since it works in practice it is turned on for master. For this reason alone I'd recommend anyone to use Plots master, rather than the release version.

Unfortunately, this means that the fix here cannot be included in a release. I was able to replicate the issue by removing my Plots.ji file and turning off precompilation. Turning it on again fixed it. But the fix in mkborregaard-fix993 did work on my system, even without precompilation. I've added that to master and pushed a new release, just in case that might take care of it. It'd be nice if some of you could try Pkg.free("Plots") to get on the released version, to see if it is better now before closing the issue.

[xiaoweiz]

Confirm that the new release 0.12.2 solves the issue.

[BoundaryValueProblems]

@mkborregaard , the new release 0.12.2 also worked for me as @xiaoweiz said. However, after updating to 0.12.2 and running using Plots, it generated the following error. Only after running using Plots once more, finally I could plot things. Is this an expected behavior?

[mkborregaard]

Well, it's a response to precompilation being turned off for a package, and will only occur once. But again, I'd strongly recommend just staying on master.

[BoundaryValueProblems]

@mkborregaard , thanks! OK, I'll stay on master from now on.

[ankit48365]

Probably? Still can't reproduce this though. @currymj Can you try Pkg.checkout("Atom")?

Guys, I can't run this command, where do we run this command from to checkout,

[BoundaryValueProblems]

@ankit48365: This thread is obsolete. Also, Pkg.checkout command is obsolete after Julia v1.0. Since you are using Julia v1.4.1, you need to use either Pkg.add or Pkg.develop depending on what you want to do. The following discourse forum thread may be of your help: https://discourse.julialang.org/t/pkg-checkout-in-julia-1-0/13907 Also, please check the latest manual of Pkg.jl: https://docs.julialang.org/en/v1/stdlib/Pkg/ or more details at: https://julialang.github.io/Pkg.jl/v1/ Best, BVPs
