What does "Error in file.exists(pythonPath) : file name conversion problem -- name too long?" mean?

Question

I uninstalled and reinstalled R and RStudio. I installed R v.4.2.2 and RStudio 2022.12.0+353. And when I start a new R session or restart the session, I get that message with the error in the console.

It doesn't seem to generate problems with my markdowns when I run the codes, but I'd like to know what this error means. I only use the R programming language, I don't use Python.

Answer 1

I had the same issue on windows 10 with Rstudio 2022.12.0 Build 353 with R 4.2.2 (2022-10-31 ucrt), and I solved it by unticking the "Automatically activate project-local Python environments" option that can be found by going to Tools > Global options... > Python".

Edit: you may also add your favorite python interpreter, which, as expected, is also another way to solve this error.

I still have to test and play around to see if this will be useful for me, but you can even select a python from a specific conda environment as your default interpreter.

I won't get into what seems to be the recommended practices, but I found this blog post by Posit on how to set and use Python in Rstudio
