Hi,  
When I start Julia in Atom, I get the following warning. ‘julia-client’ and all the packages are up to date. I just updated it earlier today. After the update, I tried to run an example from the repo, but I couldn’t as atom/julia got stuck and didn’t gave me anything (no warnings/errors/results/updates). Later when I quit julia and started it again, I got the folllowing warning.

Starting Julia…

Did you do execute:

```julia
using Pkg; Pkg.update()

```

Then restart the tray?

Thanks @pixel27 for your response.

Yes, I did try Pkg.update(). All the packages are up to date. julia-client in atom is also up to date. I’m not sure what is causing the error.

New user here, just updated Julia from 1.3 to 1.4 and changed the juliaPath in a config.cson accordingly, and I see the same error message. Weirdly it doesn’t show up when I start Julia the first time after opening Atom, but when I start Julia after stopping Julia at least once.

What version of Atom.jl and julia-client do you have installed?

Make sure to update the Atom package `julia-client` (might require an Atom update, if you’re using an old version), as indicated in the warning.

I had the same problem after updating the juliapro version. The thing is that after installing the updated version, the old one was still available.  
So when opening atom you need to select the newest version. At least for me that solved the problem
