Does not start on M1 Macbook

I installed successfully via pip3 install -U radian

Starting from the console throws this error:

Traceback (most recent call last):

Same with development version.

Hi all, the following step solved the issue: Adding export R_HOME=/Library/Frameworks/R.framework/Resources to .zshrc which allows radian to find the version of R that is used by Rstudio. Hope this helps others who may have a similar problem. Thanks.

Great that you solved it. That path is for the standard CRAN R, used by RStudio. Both are x86 atm, so now R matches your anaconda environment architecture-wise. You should be able to use pandoc, etc. all fine too as long as it’s x86 (no arm version yet, as I mentioned above). Basically, if everything is Rosetta emulated everything works. If everything is arm, it also works. (e.g. in my case: native VSCode, native R, native radian). Mixing though typically doesn’t work.
