库不可写 [英] Library is not writable

问题描述

我在 Ubuntu 机器上安装 R 版本 3.0.2 (2013-09-25) 时遇到此问题:

I have this issue during package installation in R version 3.0.2 (2013-09-25) on an Ubuntu machine:

install.packages("randomForest")
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning in install.packages :
  'lib = "/usr/local/lib/R/site-library"' is not writable

如何解决?

推荐答案

对于 R 版本 3.2.2 (2015-08-14) 应该解决这个问题，因为 R 在安装过程中建议使用不同的路径来存储 R图书馆.安装看起来像这样:(这里以'random'作为示例包)

For R version 3.2.2 (2015-08-14) this problem should be dealt with since R suggests within the installation process a different path to store your R libraries. The installation looks like this: (Here 'random' is used as an example package)

install.packages('random')

Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning in install.packages("random") :
'lib = "/usr/local/lib/R/site-library"' is not writable

Would you like to use a personal library instead?  (y/n) y

Would you like to create a personal library
~/R/pc-linux-gnu-library/3.2
to install packages into?  (y/n) y

所以在安装过程中用y"回答这两个问题应该正确安装包.

So during the installation answering both questions with 'y' should install the package correctly.

如果您不想将 R 包存储在其他文件中:

In case you don't want to store your R packages in an additional file:

作为 Antoine-Sac 和 Robert TheSim 指出您可以将自己添加到员工组中，以便能够写入站点库".(点击名字可以看到他们的重要补充)

As Antoine-Sac and Robert TheSim point out you can add yourself to the staff group in order to be able to write to 'site-library'. (Click on the names to see their important additions)

在此更新之前，我在此评论中提到了使用chmod o+w"更改文件夹site-library"权限的选项，以便能够对其进行写入.假设存在安全问题，但当时我无法告诉我警告，但主要是在等待某人解决这个问题.Antoine-Sac 和 Robert TheSim 同时这样做了.谢谢！

Before this update I mentioned in this comment the option of changing the permission of the folder 'site-library' using 'chmod o+w' in order to be able to write to it. Assuming security issues but unable to tell at the time I warned about it but have primarily been waiting for somone to clear this up. Antoine-Sac and Robert TheSim have done so in the meantime. Thanks!
