推荐答案
如在此由RStudio支持:
As stated here by RStudio Support:
如果遇到问题，建议您尝试在R中安装软件包 (在RStudio之外)，看看您是否能够做到这一点.如果没有，请 请在下面查看可能的解决方案.
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， - 但是，R控制台必须以sudo特权启动(否则，它将再次失败，并出现perssion拒绝错误):
sudo R， - 然后安装所需的任何软件包:
install.packages("mlbench").
- switch to
Terminal.app, - however, R console must be started with the sudo privileges(otherwise, it will yet again fail with a perission denied error):
sudo R, - and then install whatever package is necessary:
install.packages("mlbench").
