RStudio更新到R 3.4后看不到软件包 [英] RStudio does not see packages after update to R 3.4

问题描述

我有Ubuntu 16.04，将R更新到3.4.1版本后，即使它们也已更新，它也看不到我的软件包:

I have Ubuntu 16.04 and after update of R to 3.4.1 version it does not see my packages even though they have also been updated:

> library(dplyr)
Error in library(dplyr) : there is no package called ‘dplyr’

包在那里:

$ ls ~/R/x86_64-pc-linux-gnu-library/3.4/ | grep plyr
dplyr
plyr

我的.libPaths:

> .libPaths()
[1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"       "/usr/lib/R/library" 

将.libPaths设置为所需路径仅适用于一个会话.我希望它是永久的.

Setting .libPaths to desired path does the thing just for one session. I'd like it to be permanent.

我还尝试将变量R_LIBS，R_LIBS_SITE和R_LIBS_USER设置为所需的路径，如

I also tried to set the variables R_LIBS, R_LIBS_SITE and R_LIBS_USER to desired path as indicated here but it worked only in the console (didn't work in RStudio).

推荐答案

找到了解决方案: 在文件/usr/lib/R/etc/Renviron中，存在R的配置.

Found the solution: In the file /usr/lib/R/etc/Renviron there is a configuration of R.

第43-45行有:

# edd Jun 2017  Comment-out R_LIBS_USER
#R_LIBS_USER=${R_LIBS_USER-'~/R/x86_64-pc-linux-gnu-library/3.4'}
##R_LIBS_USER=${R_LIBS_USER-'~/Library/R/3.4/library'}

我没有评论R_LIBS_USER=${R_LIBS_USER-'~/R/x86_64-pc-linux-gnu-library/3.4'}，重新启动了RStudio，现在可以使用了.

I have uncommented R_LIBS_USER=${R_LIBS_USER-'~/R/x86_64-pc-linux-gnu-library/3.4'}, restarted RStudio and now it works.

编辑:查看评论，似乎是有计划的行为. 这里是另一种解决方案.

Looking at the comments, it seems like a planned behaviour. Here is another solution.
