加載Swirl軟件包時出現問題

Question

我能夠安裝漩渦包裝，但是當我給出庫（漩渦）命令時，出現以下錯誤：

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’

所以我嘗試安裝蠟筆軟件包，它顯示為：

* 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 :

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

如何解決此問題並裝入旋流包裝？

嘗試直接從Github加載它，看看它是否解決了問題。 您可能需要在此之前重新啟動R實例，以確保一切正常。

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