重新安装后加载tidyverse错误-R (loadNamespace、backports、backports)

Question

我刚刚将R更新为4.0.2，将RStudio桌面更新为1.3.959。如下面的代码所示，在安装成功之后，我是无法加载tidyverse。但是，data.table安装和加载非常好。有人有这方面的经验吗？谢谢!

来自控制台的代码(tidyverse错误)：

包backports可能会出现一些问题:尝试重新安装该包并再次加载tidyverse：

install.packages("backports")
library(tidyverse)

如果这样做不起作用，那么在R的早期主要版本(即3.x)下构建的软件包可能会出现问题。尝试用以下方式重新安装所有软件包：

update.packages(ask = FALSE, checkBuilt = TRUE)
