ERROR: LoadError: Cannot find Electron.

[gtollefson]

Hi,

After updating all of my julia packages, including PlotlyJS.jl and plots.jl, I receive the following error when running: PlotlyJS.savefig(graphic_group1, "R_project_group1.pdf")

I have tried Blink.AtomShell.install() of course and have also tried Pkg.update("PlotlyJS") and Pkg.checkout("PlotlyJS"). I'm using this for a project I'm presenting later today so any help would be very appreciated!

ERROR: LoadError: Cannot find Electron. Try Blink.AtomShell.install().

[gtollefson]

I should mention I have also installed rsvg and cairo and this function worked fine until updating my packages.

[sglyon]

Hmm, sorry to hear about that. Let's get to the bottom of it!

Can you give more information about your setup? Could you please answer these questions:

• What is your operating system
• what versions of PlotlyJS.jl and Blink.jl are you using
• where are you running the code (repl, jupyter, Juno (atom), or vs code, etc.)

[gtollefson]

Thanks for your quick reply @sglyon !

• Mac OS High Sierra 10.13.2

• running Julia 0.6.0

• PlotlyJS 0.10.0

• Blink.jl 0.6.0

• Running my script from the command line

[sglyon]

hmm.. very similar to my setup. Can you hop on Gitter for a quicker chat to figure it out?

[gtollefson]

Certainly. Thank you!

[sglyon]

using Blink
Blink.AtomShell.remove()
Blink.AtomShell.install()

fixed the issue

[StefanPofahl]

I have troubles to follow your advice. I guess Blink.AtomShell.remove() is now Blink.AtomShell.rm().
If I send the command: Blink.AtomShell.install() I see:

[mzaffalon]

Your solution does not work anymore? JuliaGizmos/Blink.jl#286 (comment)

[StefanPofahl]

To be honest I had forgotten that I posted this here ...
It is strange, the current version of this zip-file does not contain a folder /src/
I have already deleted: Project.toml and Manifest.toml in the folder ../environments/v1.6
but this was not enough ...
Now cannot even install PlotlyJS successfully. I do not know what to do ...

[mzaffalon]

I install PlotlyJS regularly with Julia 1.8 and I don't see the problem you described.

[StefanPofahl]

Yes, that is also my conclusion, that I should switch to Julia v1.8 ...
I do not know by when I find the time to install and test it.

[StefanPofahl]

It is strange, the current version of this zip-file does not contain a folder /src/

P.S.:
I figured out that the /src/ folder is included in the zip-archive of the Blink-package.
The electron-v4.0.4-linux-x64.zip contains the electron-executable.

[StefanPofahl]

Unfortunately, also under Julia v1.8.3 I face issues:

[BeastyBlacksmith]

The error message says that you don't have write permission. Are you on a cluster or similar?

[StefanPofahl]

Thanks for your reply! - It is my own computer, the .julia folder is local.
Yesterday I installed Julia v1.8.3 to exclude a Julia version issue with julia-LTS.
Bevore my new attempt to install Blink.jl I have removed the entire folder ~/.julia/packages as well as the folder ~/.julia/environments. In addition I have started the julia process as admin: sudo julia.
The error message is still there and quite strange.
First thing I tried is to find the command curl ..., this was not successful, I guess this command
is invoked by:

download("https://github.com/electron/electron/releases/download/v$version/$file")

inside:

~/.julia/packages/Blink/mwJC9/src/AtomShell/install.jl

In the script:

.julia/packages/Blink/mwJC9/src/AtomShell/process.jl

I found the hint, where Blink.jl expects the executable electron:

const _electron = resolve_blink_asset("deps/atom/electron")

I added the folder:

.julia/packages/Blink/mwJC9/deps/atom/

and copied into this folder the content of: electron-v4.0.4-linux-x64.zip.
Now it is possible to build the package Blink inside the Pkg-Mode:

(@v1.8) pkg> build Blink

It would be interesting to figure out what the current folder is, in the moment the curl-command is executed.
