r - makeCluster 在 Windows 上挂起 - 并行包

Question

我尝试使用并行包在我的 Windows 10 笔记本电脑上的 R 中运行简单的并行化，但是当它到达 makeCluster 函数时，它只是挂在那里。我尝试在 GUI 上运行，不同数量的内核，更改 Windows 防火墙上的设置并使用雪包，但无济于事。

这是我一直在使用的代码：

library(doParallel) # basic parallelization package
ncore <- detectCores(logical = TRUE) # detect number of cores
cl <- makeCluster(ncore - 1, type = "PSOCK") # create clusters of ncore - 1

有没有遇到类似问题的人知道如何解决这个问题？非常感谢你的帮助！

编辑：正如建议的那样，这里是运行代码的日志文件的摘录。我尝试查看显示的错误，但没有成功：
