I am trying to start Julia interpreter in VSCode with additional arguments -p 4 and getting this error.

```julia
ERROR: LoadError: On worker 2:
ArgumentError: Package VSCodeServer [9f5989ce-84fe-42d4-91ec-6a7a8d53ed0f] is required but does not seem to be installed:

```

I’m guessing the package VSCodeServer isn’t being loaded `@everwhere` in the terminal that VSCode starts. The same setup works in Atom without any issues. Any thoughts on how to work around this problem?

Is this what you’re looking to do?
