每次我在RStudio中打开新会话时，都会收到错误消息:
Error: C stack usage 7953936 is too close to the limit
基于对here和here发布的类似问题的建议，我try 在终端中使用ulimit命令，但出现以下错误.
Isabels-MacBook-Pro ~ % ulimit -s
8176
Isabels-MacBook-Pro ~ % R --slave -e 'Cstack_info()["size"]'
Error: C stack usage 7954496 is too close to the limit
Execution halted
然而，当我独自运行ulimit时，我得到:
Isabels-MacBook-Pro ~ % ulimit
unlimited
为了再次判断，我再次try 将其设置为无限:
Isabels-MacBook-Pro ~ % ulimit -s unlimited
但接下来会出现一个新错误:
Isabels-MacBook-Pro ~ % R --slave -e 'Cstack_info()["size"]'
Error: evaluation nested too deeply: infinite recursion / options(expressions=)?
Execution halted
我不知道在这种情况下这意味着什么.Cstack_info()位是否被无限递归卡住了？？我很想弄明白这一点，因为它正在妨碍安装一些必要的软件包！
如果有帮助，以下是我的课程信息

# REMEMBER to restart R after you modify and save this file!
# First, execute the global .Rprofile if it exists. You may configure blogdown
# options there, too, so they apply to any blogdown projects. Feel free to
# ignore this part if it sounds too complicated to you.
if (file.exists("~/.Rprofile")) {
base::sys.source("~/.Rprofile", envir = environment())

有没有什么明显的东西可能会导致这个问题？
