错误:在R启动时，C堆栈使用率太接近限制

Question

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

根据这里和这里发布的类似问题的建议，我尝试在终端中使用ulimit命令，但出现了以下错误。

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，当我自己运行ulimit时，我会得到：

Isabels-MacBook-Pro ~ % ulimit
unlimited

只是为了再次检查，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((是不是被无限递归卡住了？？我很想弄清楚这一点，因为它阻碍了安装一些必要的软件包！

如果有用的话，这是我的会话信息

R version 4.1.3 (2022-03-10)
Platform: x86_64-apple-darwin17.0 (64-bit)
Running under: macOS Monterey 12.2.1

和.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
options(blogdown.hugo.version = "0.82.0")

这里有没有什么明显的东西可能会引起这个问题？

Answer 1

您的用户.Rprofile文件由于某种原因正在递归加载：

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

从您的评论来看，这些行似乎位于~/.Rprofile内(~扩展到用户主目录，即/Users/mycomputer，假设mycomputer是您的用户名(。

删除这些行(或注释掉(，它们不属于此处。事实上，该文件看起来像是特定于项目的.Rprofile配置的模板。这在项目目录中是有意义的，但对于概要文件范围的用户.Rprofile来说就没有意义了。

这些文件的逻辑如下：

• 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设置为文件的路径，R将尝试加载此文件
• 否则，如果文件~/.Rprofile存在，R将尝试加载该文件

现在，这意味着如果存在特定于项目(=在当前工作目录中(的.Rprofile，则不会自动加载~/.Rprofile。这是不幸的，因此许多项目将类似于上面的行添加到其项目特定的.Rprofile文件中，以导致用户范围的~/.Rprofile也被加载。但是，上面的实现忽略了R_PROFILE_USER环境变量。因此，更好的实现方式如下：

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

成功！感谢评论中的每一个人。通过删除/Library/framework/R.framework/Resources/Library/base/R/Reprofile并重新安装R和Rstudio，问题得到了解决。
