【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。如下面的代码所示，在似乎成功安装后，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）：

标签： r tidyverse

【解决方案1】：

backports 包可能有问题：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，则在早期的 R 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)

感谢您的帮助！安装包backports 帮助我找到了解决方案。在安装backports 时，我不得不在询问我是否要从源代码安装的提示中选择“否”。从源代码安装导致我在上面发布的相同错误。运行library(tidyverse) 然后给出关于包fs 的错误，所以我还必须安装包fs，同样不是来自源代码。
@IanMalone 谢谢，太好了，很高兴它对你有用！安装二进制版本的软件包确实似乎是更安全的方式（而不是源代码）。
