推荐答案

如在此由RStudio支持:

As stated here by RStudio Support:

您可以在R中安装软件包吗?

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").
