如何解决Rstudio 因 brms 功能崩溃

我以前使用 brms 没有问题，但现在 Rstudio 崩溃了。

为了获得错误消息，我在项目的 .Rmd 文件中使用了一个块，但是当我在项目外和 R 文件中执行相同的代码时，它不会改变。

我安装了最后一个 Rstudio 版本，它没有改变。我尝试更改为 AGG 图形选项，但没有更改 (Github issue)。

我使用：

Ubuntu 20.04
Rstudio 1.4.1106
R 4.0.5 (2021-03-31) -- "Shake and Throw"，平台 x86_64-pc-linux-gnu（64 位）

我使用第一个 brms 示例作为可重现的示例：

library(brms)
prior1 <- brms::prior(normal(0,10),class = b) +
  brms::prior(cauchy(0,2),class = sd)

fit1 <- brms::brm(count ~ zAge + zBase * Trt + (1|patient),data = brms::epilepsy,family = poisson(),prior = prior1)

在 RStudio 中不删除任何文件

我明白了：

从终端单独使用 R :

我明白了：

Floating point exception (core dumped)

和窗口告诉我“应用程序 R 已意外关闭”。无论我是否从 .r/crashpad_database/pending 中删除 .lock 文件，结果都是一样的。

打开了另一个问题，但他们只讨论图形，我看不出这与我的问题 Another Github issue 有什么关系。

我现在失去了希望，但如果有人有想法，我会很高兴阅读它;)

@BenBolker 的解决方案：

install.packages("cmdstanr",repos = c("https://mc-stan.org/r-packages/",getoption("repos")))

library(cmdstanr)

install_cmdstan()

set_cmdstan_path(path = NULL)

library(brms)

prior1 <- brms::prior(normal(0,prior = prior1,backend = "cmdstanr")

斯坦工作正常！

然而，我仍然想知道为什么 brm() 函数在没有这个后端选项的情况下可以工作，我不明白解决方案（我不是计算机科学家，因此我真的很挣扎），我仍然担心，因为brm() 函数使 R 在没有后端选项的情况下崩溃。
