Using R libraries fail with pixi library

OS: Darwin x64 23.5.0

Steps to reproduce the issue:

The issue is that trying to load or use libraries that are located in a .pixi folder. This works just fine in RStudio.

1. Install pixi
2. Create new R project with pixi exec copier copy gh:roaldarbol/r-template test-repo
   • Follow instructions. I used R version 4.3 (which then defaults to the 4.3.3)
   • Adding Positron when asked doesn't actually do anything yet, so it doesn't matter whether it's selected
3. cd test-repo
4. Add a package (for testing later, e.g. pixi add r-dplyr)
5. Open Positron from command line (on MacOS pixi run open -a positron)
6. Open test-repo project folder
7. Confirm library is in path - in the console run .libPaths()
8. Confirm that the library command can see the libraries - run library()
9. Run library(dplyr) - see error
   • Error in library.dynam(lib, package, package.lib) : shared object ‘rlang.so’ not found
10. Similarly, try running a command from the library - dplyr::filter()
    • Error: 'catch_cnd' is not an exported object from 'namespace:rlang'

What did you expect to happen?

I expected the library to load.

Were there any error messages in the Output panel or Developer Tools console?

Nothing suspocious in the Developer Tools Console (except that the logo doesn't load - but that's unrelated):

PS

Could we consider adding a test for R+conda too in #3879?

[roaldarbol]

Something might have broken in my system, I have the same issue in RStudio now...

[roaldarbol]

It seems that using Positron pushed the system-wide library in front of the project-based library. That persisted when I went back to RStudio. I removed it again with .libPaths(.libPaths()[2]). I think it was because it's not possible to open a project from the command line (#4049), then opening Positron uses a global R installation, and the library carried over and "superseded" the project library, when changing into a project even though the project had environment variables to set the libraries.

When I open RStudio, R.home() points to the pixi installation, whereas when I run R.home() in Positron, it points to the system-wide installation. So I guess Positron is not able to use a conda R installation (I knew the discovery didn't work yet, but I somehow imagined that if RStudio picked up the installation on start-up, the Positron would too)

Yes, I think this is related to #3724 where Positron does not know about Pixi R interpreters at all as of today. Thanks for the report!
