VS Code and Julia - Unable to run Julia applications via CTRL+F5

Question

I'm trying to get the Julia extension working in VS code. I can run Julia files via the REPL and I can debug Julia files in a new process. However I cannot run Julia files in a new process . In other words, whilst all other run options work, the circled option in the image below does not.

What could be the reason for this?

I am using the newest stable version of Julia (1.7.3), and VS code is fully updated. I am using version 1.6.28 of the Julia VS code extension. I am also using Windows 10. When using CRTL+F5 I get no feedback from VS code at all. Whilst a counter does appear in the Run and Debug pane, the runtime instance isn't displayed in the call stack until I run the file another way. For example, if I launch VS code and run a Julia file with "Run File in New Process" the run and debug pane looks as follows:

If I then run the same program again with "Debug File in New Process", the Run and Debug pane updates as follows:

The only other weird behaviour I notice is when the Julia Language Server loads. I get the following output in the Julia Language Server:

[ Info: Received new data from Julia Symbol Server.

I also get the following output in "Tasks" after using "Debug File in New Process":

Error: there is no registered task type 'julia-proc'. Did you miss installing an extension that provides a corresponding task provider?

I don't get the same output in "Tasks" if one of the other two run commands is used instead.

Answer 1

I do get the same output prompt but unlike you I can run files in new processes. Perhaps your problem lies elsewhere.

Answer 2

I ran into this issue as well. I resolved it by opening a new bash terminal tab, running import Pkg; and then Pkg.add("DynamicalSystems") in a julia REPL, and adding a Configuration in VS Code to 'Run active Julia file'. I believe you need to run Pkg.add(<insert package name in quotes>) for all of the dependencies for the particular file you're trying to run.
