RE: EOFError: read end of file

[mdhe1248]

I have this issue:
I installed the generic linux binary Julia0.5. Then I wanted to use plotly. However, I encountered an error. "EOFError: read end of file".

I ran the commends below:

julia> Pkg.add("PlotlyJS")

That error happens when blink doesn't get set up properly when you call using PlotlyJS. this probably happened because you had to install electron (formerly called Atom shell) after trying to load blink.

Will you try to plot something again in a fresh Julia session and let me know what happens?

Hi,
I re-ran my Julia session. I am getting the same issue:

Hmm @mdhe1248 thanks for posting again. I don't actually know what that issue is and unfortunately I can't reproduce and don't have the time to vicariously debug right ow.

Perhaps @MikeInnes has some idea as the issue seems to originate inside Blink?

[mdhe1248]

Thank you for spending time on this issue.
I have an update: I run Julia in our server. The error occurs when I connect our server through "NoMachine".

I use ssh. If I connect our server directly from my ubuntu via ssh, PlotlyJS works fine. If I run Nomachine first, then use ssh (in Nomachine), I get the error. Do you have any insights on this problem?

[sglyon]

Hmm, I'm sorry but I haven't been able to get PlotlyJS to work reliably over ssh myself.

I think it amounts to having Blink.jl open windows on the user's machine rather than on the machine running the Julia process, but I don't believe that has been implemented yet.

Closing due to inactivity. Please re-open if this is still an issue we can help with
