我在Windows中执行Rstudio。当我尝试执行函数rstudioapi :: getActiveDocumentContext（）时，它返回＆＃34;错误：评估嵌套太深：无限递归/选项（表达式=）？＆＃34;
这是我的会话代码：
library(rstudioapi)
rstudioapi::isAvailable()
rstudioapi::getActiveDocumentContext()
控制台输出为：
> library(rstudioapi)
> rstudioapi::isAvailable()
[1] TRUE
> rstudioapi::getActiveDocumentContext()
Error: evaluation nested too deeply: infinite recursion / options expressions=)?
Error during wrapup: evaluation nested too deeply: infinite recursion / options(expressions=)?
这是sessionInfo（）输出：
> sessionInfo()
