r - 无法运行漩涡（）

Question

无法启动漩涡。

我已经安装并加载了漩涡包。

> install.packages("swirl")
> library("swirl")
> swirl()

下面写的是我得到的错误

> swirl()
Error in match.arg(type, c("success", "failure", "error", "skip","warning")) : 
     'arg' must be NULL or a character vector

| Leaving swirl now. Type swirl() to resume.

这是我的 sessionInfo()
