尝试在 Rstudio 中安装软件包时出错

Question

我正在尝试在我的 windows 计算机上的 Rstudio 中安装一些软件包，但我遇到了一些问题。 当我输入：

install.packages("dplyr") 

我收到以下错误：

Warning in install.packages :
  unable to access index for repository https://cran.rstudio.com/src/contrib:
  internet routines cannot be loaded
Warning in install.packages :
  unable to access index for repository https://cran.rstudio.com/src/contrib:
  internet routines cannot be loaded
Warning in install.packages :
  package ‘dplyr’ is not available for this version of R

A version of this package for your version of R might be available elsewhere,
see the ideas at
https://cran.r-project.org/doc/manuals/r-patched/R-admin.html#Installing-packages
Warning in install.packages :

我还尝试通过以下方式安装软件包：

> install.packages("C:/Users/NLFERM/Downloads/dplyr_1.0.4.tar.gz", repos = NULL, type = "source")

但在这里我也得到一个错误：

ERROR: dependencies 'ellipsis', 'generics', 'glue', 'lifecycle', 'magrittr', 'R6', 'rlang', 'tibble', 'tidyselect', 'vctrs' are not available for package 'dplyr'
* removing 'C:/Users/NLFERM/Documents/R/R-4.0.4/library/dplyr'
Warning in install.packages :
  installation of package ‘C:/Users/NLFERM/Downloads/dplyr_1.0.4.tar.gz’ had non-zero exit status

我已经重新安装了 R studio 并确保我的计算机上安装了最新版本的 R。 有谁知道如何解决这个问题？

亲切的问候

这适用于您的 R 底座吗？

否则你连接到互联网了吗？ 或者通过无法访问 cran 网站的企业网络？
