如 RStudio 支持所述here：

Are you able to install packages in R?

If you're having issues, we recommend trying to install packages in R (outside of RStudio) and see if you're able to do that. If not, please check the possible solutions below.

因此，需要：

切换到Terminal.app,
在您的终端内，您的 R 控制台必须以 sudo 权限启动。否则，它将再次失败并出现权限被拒绝的错误。因此，在您的终端中，键入 sudo R、
然后安装任何必要的包：例如install.packages("mlbench").
