在R上安装factoextra时出错-无法删除以前安装的rlang

Question

我正在尝试安装factoextra。我运行的是R v.4.0.3。我用过

    > install.packages("devtools")
    > library("devtools")
    > install_github("kassambara/factoextra")

然后，它会询问我是否希望更新这些包：

WARNING: Rtools is required to build R packages, but is not currently installed.

Please download and install Rtools 4.0 from https://cran.r-project.org/bin/windows/Rtools/.
Downloading GitHub repo kassambara/factoextra@HEAD
These packages have more recent versions available.
It is recommended to update all of them.
Which would you like to update?

1: All                          
2: CRAN packages only           
3: None                         
4: rlang (0.4.8 -> 0.4.9) [CRAN]

所以我选择1来更新所有的包，它返回如下：

    package ‘rlang’ successfully unpacked and MD5 sums checked
Error: Failed to install 'factoextra' from GitHub:
  (converted from warning) cannot remove prior installation of package ‘rlang’

我几乎没有使用R的经验，我真的不知道该怎么做。我需要额外的factoextra，这样我才能运行fviz_pca命令。

感谢您所能给予的任何帮助

如果已经加载了rlang，则会出现此错误。请参阅this上一篇文章。
