如何将 R_HOME 环境变量设置为 R 主目录? [英] How to set the R_HOME environment variable to the R home directory?

问题描述

我正在尝试将 rpy2 导入 python，但出现此错误:

I am trying to import rpy2 into python and I am getting this error:

RuntimeError: The R home directory could not be determined.
Try to install R <https://www.r-project.org/>,
set the R_HOME environment variable to the R home directory, or
add the directory of the R interpreter to the PATH environment variable.

我完全迷失在这里，因为我不知道这在告诉我什么.我试图搜索如何设置环境变量，但找不到任何对我有帮助的足够详细的信息.如果答案非常简单，我将不胜感激，因为我只是一个新手.我正在运行 OSX 10.11.

I am completely lost here as I have no idea what this is telling me. I tried to search up how to set the environment variable and couldn't find anything detailed enough that was helpful for me. I would appreciate it if the answer could be very straightforward as I am just a newbie. I am running OSX 10.11.

谢谢(我的第一篇文章，如果我忽略了发布规则，我深表歉意)

Thank you (my first post, I apologize if I overlooked any rules in posting)
