rappdirs not finding win_path when running from command line

[fermumen]

I'm getting an error from rappdirs when trying to run a script based on AzureVM. This is the error I get, I'm asuming it can't find the auth cache location? How could I fix it?

"Rscript.exe" "main.R"
Error: package or namespace load failed for 'AzureVM':
.onLoad failed in loadNamespace() for 'AzureAuth', details:
call: .Call("win_path", csidl, PACKAGE = "rappdirs")
error: "win_path" not available for .Call() for package "rappdirs"
Execution halted

I'm running from PowerShell on Windows with this session info

I can't repro this. Can you provide a reproducible example? I assume you're calling an R file using Rscript.exe, from within a Powershell script?

Also, does AzureAuth work correctly in an interactive session?

Hi,
I tried to reproduce it on another machine and it was all working. This must be an edge case generated by my workplace virtualized environment.
My Rscript.exe call is:

C:\ProgramData\App-V\8A6DA061-8C87-48F2-9868-6FDB6343D4F7\230E76A8-6D41-430E-85D7-6E404165F588\Root\R-4.0.2\bin\Rscript.exe "path/to/script.R"

AzureAuth works correctly from an interactive session and finds the Azure_dir in :
C:\Users\<MyUser>\AppData\Local\Microsoft\AppV\Client\VFS\8A6DA061-8C87-48F2-9868-6FDB6343D4F7\Local AppData\AzureR

Somehow when I run Rscript from the command line (running just AzureAuth::Azure_dir()) it gives me the above error.

It seems that these are more likely than not part of the virtual app configuration. Is there a way to hardcode into the script the Azure_dir()?

This seems to be more likely a problem with the rappdirs package. See if the following works:

rappdirs::user_data_dir(appname="AzureR", appauthor="", roaming=FALSE)

Right now there's no way to hardcode the cache directory. I'll add that to the next version.

In the meantime, you could create a dummy rappdirs package that just returns a fixed value when you call the above function. I don't think many other packages use it, so you should be safe.

You are right, it is a rappdirs issue.

Thanks for the suggestion for the dummy package and for your help!

Actually, you could also try installing rappdirs 0.3.2. This lets you specify the directory in the R_USER_DATA_DIR environment variable, maybe that will bypass the offending C code.
