library(tidyverse)
Error: package or namespace load failed for ‘tidyverse’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called ‘reprex’
我正在使用此版本的 R 版本 4.0.3 (2020-10-10) 我也尝试安装库“reprex”,但我有这个
install.packages("reprex")
also installing the dependency ‘withr’

我有 macOS Big Sur
答案 0 :(得分:1)
我在 MacOS big sur 上也遇到了完全相同的问题。它现在确实有效。我安装了 ggplot2 install.packages("ggplot2")
,它也安装了 withr,它以前找不到的包。
同时安装依赖‘withr’

之后,我再次安装了tidyverse,问题解决了。

我不确定该解决方案是否确实安装了 ggplot2。这是我第一次使用 R。(我在 edX 上学习数据科学课程)
干杯!
