r - 全新安装后加载 tidyverse 时出错 - R (loadNamespace, broom, backports)

问题描述

我刚刚将 R 更新到 4.0.2 版，并将 RStudio Desktop 更新到 1.3.959 版。从下面的代码中可以看出，在似乎成功安装之后，我无法加载 tidyverse 。但是， data.table 安装和加载非常好。这个事情谁有经验？谢谢！

来自控制台的代码（tidyverse 错误）：

解决方案

包可能存在一些问题backports：尝试重新安装该包并再次加载 tidyverse：

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

如果这不起作用，那么在 R 的早期主要版本（即 3.x）下构建的软件包可能存在问题。尝试使用以下命令重新安装所有软件包：

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