Error: C stack usage is too close to the limit at R startup

Question

每次我在 RStudio 中打开一个新会话时，都会收到错误消息：

Error: C stack usage  7953936 is too close to the limit

根据 and here 发布的类似问题的建议，我尝试在终端中使用 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，当我运行自己使用 ulimit 时，我得到：

Isabels-MacBook-Pro ~ % ulimit
unlimited

为了仔细检查，我再次尝试将其设置为无限制：

Isabels-MacBook-Pro ~ % ulimit -s unlimited

但随后出现新错误：

Isabels-MacBook-Pro ~ % R --slave -e 'Cstack_info()["size"]'
Error: evaluation nested too deeply: infinite recursion / options(expressions=)?
Execution halted

我不知道这在这种情况下意味着什么。 Cstack_info() 是否卡在了无限递归中？我很想弄清楚这个问题，因为它妨碍了安装一些必要的软件包！

如果有帮助，这是我的会话信息

以及 .Rprofile 的内容

# 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())
}

# Now set options to customize the behavior of blogdown for this project. Below
# are a few sample options; for more options, see
# https://bookdown.org/yihui/blogdown/global-options.html
options(
  # to automatically serve the site on RStudio startup, set this option to TRUE
  blogdown.serve_site.startup = FALSE,
  # to disable knitting Rmd files on save, set this option to FALSE
  blogdown.knit.on_save = TRUE,
  # build .Rmd to .html (via Pandoc); to build to Markdown, set this option to 'm$
  blogdown.method = 'html'
)

# fix Hugo version

是否有任何明显的问题可能导致此问题？

Answer 1

您的用户 .Rprofile 文件出于某种原因正在递归加载自身：

if (file.exists("~/.Rprofile")) {
  base::sys.source("~/.Rprofile", envir = environment())
}

从您的评论来看，这些行似乎在 inside ~/.Rprofile（~ 扩展到用户主目录，即 /Users/mycomputer in你的情况，假设 mycomputer 是你的用户名）。

删除这些行（或将它们注释掉），它们不属于这里。事实上，该文件看起来像是 project-specific .Rprofile 配置的模板。它在项目目录中是有意义的，但作为 profile-wide 用户 .Rprofile.

logic for these files如下：

如果当前目录中有 .Rprofile 文件，R 会尝试加载该文件。
否则，如果环境变量 R_PROFILE_USER 设置为文件路径，R 会尝试加载该文件。
否则，如果文件 ~/.Rprofile 存在，R 会尝试加载它。

现在，这意味着如果 projects-specific（= 在当前工作目录中）.Rprofile 存在，则 ~/.Rprofile 不会自动加载.这很不幸，因此许多项目将类似于上面的行添加到它们的 project-specific .Rprofile 文件中，以导致 user-wide ~/.Rprofile 也被加载。但是，上面的实现忽略了 R_PROFILE_USER 环境变量。因此，更好的实现如下所示：

rprofile = Sys.getenv('R_PROFILE_USER', '~/.Rprofile')
if (file.exists(rprofile)) {
  base::sys.source(rprofile, envir = environment())
}
rm(rprofile)

Answer 2

成功！谢谢评论里的每一个人。通过删除 /Library/Frameworks/R.framework/Resources/library/base/R/Rprofile 和 re-installing R 和 Rstudio.
