我能够安装 swirl 包，但是当我给出 library (swirl) 命令时，出现以下错误：

Error: package or namespace load failed for ‘swirl’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
 there is no package called ‘crayon’

所以我尝试安装蜡笔包，它出现：

* installing *source* package 'crayon' ...
** package 'crayon' successfully unpacked and MD5 sums checked
Warning in file(file, if (append) "a" else "w") :
  cannot open file 'C:/Users/Tams/Documents/R/win-library/3.4/crayon/DESCRIPTION': No such file or directory
Error in file(file, if (append) "a" else "w") : 
  it's not possible to open the conection
ERROR: installing package DESCRIPTION failed for package 'crayon'

Warning in install.packages :
  installation of package ‘crayon’ had non-zero exit status

我该如何解决这个问题并加载漩涡包？

尝试直接从 Github 加载，看看能否解决问题。您可能希望在此之前重新启动您的 R 实例，以确保一切正常。

devtools::install_github("r-lib/crayon")
library(crayon)
