All discovered R installations are unusable by Positron.

Hi community, encounter an issue using positron with R, customBinaries are set within settings.json file like suggested here, which is runnable in command line to bring up the R interpreters above 4.4 version. But positron complained that No usable R installtions. All discovered R installations are unusable by Positron. from its log file, it complained that Binary is not a shell script wrapping the executable : XXX/bin/R, while we can run XXX/bin/R in bash to bring up R. what can be the reason and how to fix it? Positron version 1.102.0. Thanks for your help

Positron looks for some key lines in the R shell script in order to use it to detect R (e.g. it must contain the text Shell wrapper for R executable). It is possible that a customization to the R startup script on your machine has removed those lines. Can you paste the output of this command?

$ cat XXX/bin/R

It would also be helpful to know:

• the full Positron version (from Help/About)
• whether this happens for you in a recent build of Positron (1.102.0 is pretty old)
• the full logs from the R Language Pack output channel
