"Cannot execute code. Unable to start a runtime for the R language." in Linux

[ZhangMH2000]

Hello Positron developers,

I'm using Ubuntu 22.04 and have downloaded Positron [2024.08.0-48]. When I try to run R scripts, I encounter the error: "Cannot execute code. Unable to start a runtime for the R language." I'm confident that R 4.3.2 is installed in my conda environment.

I checked issue #4280 and saw that version [2024.08.0-31] “addresses a problem with Positron Windows installations locating R versions”. However, the deb version of [2024.08.0-31] also produces the same error for me. I've tried some earlier versions as well, but none have worked.

Could you please provide some suggestions? Thank you!

We don't currently automatically detect R installed via conda and have #4398 to track that feature.

In the meantime, I suggest you open Positron as outlined in #4385 (comment):

• Put Positron on the path, like this
• Activate your conda env
• Launch Positron from the shell where your conda env is activated, like via positron .

Thank you! In fact I always start RStudio in different conda environments so that I can run R scripts with various R versions and packages. Really thanks!
