Randomly getting this error. Reinstalled to latest version of atom, but guess its unrelated since error persists. Any suggestions?

Try re-installing julia-client (potentially with closing Atom, `apm uninstall julia-client`, `apm install julia-client` in a terminal).

Now I’m getting Failed to activate the julia-client package error at startup.

Tried both install/uninstall from atom as well as from terminal

Do you have ink installed properly?

Updated ink and everything back to normal

What was the issue initially? Is it just a matter of promptly updating packages in atom?

The initial issue is that the update to Atom 1.41 silently broke a native dependency Juno relies on. In theory Atom should detect that and ask you to rebuild julia-client, but for some reason that failed with the last update; hence the need to reinstall manually. No idea why ink broke though, that shouldn’t have happened.

When I noticed the initial error, I had not updated atom manually though. Was there an auto update?

Yes, Atom auto-updates on Windows (and maybe on macOS as well).

How did you solve this? I met the same problem.
