I just had the exact same issue on MacOS big sur too.我在 MacOS big sur 上也遇到了完全相同的问题。 It does work now tho.它现在确实有效。 I installed ggplot2 install.packages("ggplot2") which also installed withr, the package that it could not find before.我安装了 ggplot2 install.packages("ggplot2") ，它也安装了之前找不到的 package。
also installing the dependency 'withr'还安装依赖项'withr'

After that, I installed tidyverse again and the problem was solved.之后我又安装了tidyverse，问题就解决了。

I am not sure if the solution was indeed installing ggplot2.我不确定解决方案是否确实安装了 ggplot2。 This is my first time using R.这是我第一次使用 R。 (I follow a data science course on edX) （我在 edX 上学习数据科学课程）
