rpy2 3.x not supported on Windows

[jakerhodes]

Hello, Scott,

Sorry to bother you again. I'm getting issues with the version of rpy2 installed using conda. The rpy2 version installed using conda is 2.9.4, but the import requires rpy2>=3.0.

I have tried upgrading using pip/reinstalling using pip, but I get errors such as 'sh' is not recognized as an internal or external command. I am running python 3.7.6.

Hi @jakerhodes , it looks like you should be installing with conda-forge. conda install -c conda-forge rpy2.

Hi Scott,

The installation you provided ran, but gave additional issues. I think I found my major problem, rpy2 version 3.x are not supported in Windows.

I think I'll have to run this in Linux. Thanks for all of your help!

Sorry about that! Hopefully the rpy2 authors can sort that out sooner rather than later.
