r - socketConnection中的错误（master，port = port，blocking = TRUE，open =“a + b”，：无法在Stan中打开连接（来自R）

Question

根据parallel::detectCores(). 我的防火墙已关闭。我正在stan_lmer从包中加载执行以下调用rstanarm。

hierarchical.model.1 <- stan_lmer(y ~ x1 + (1 | x2) + (1 | x3) +
                            x4 + x5 + x6 + x7 + x8,
                            data = df,
                            cores = NCORES, # NCORES = parallel::detectCores()
                            seed = SEED)

确切的错误是：

starting worker pid=12968 on localhost:11058 at 23:51:49.107
Error in socketConnection(master, port = port, blocking = TRUE, open = "a+b",  :
