R install.packages返回“无法创建锁目录". [英] R install.packages returns "failed to create lock directory"

问题描述

下载Rcpp软件包时出现此错误:

I get this error when downloading the Rcpp package:

> install.packages("Rcpp", dependencies=TRUE)
Installing package(s) into ‘/home/me/src/Rlibs’ (as ‘lib’ is unspecified)
trying URL 'http://cran.us.r-project.org/src/contrib/Rcpp_0.10.2.tar.gz'
Content type 'application/x-gzip' length 2380089 bytes (2.3 Mb)
...
Warning in dir.create(lockdir, recursive = TRUE) :
  cannot create dir '/home', reason 'Permission denied'
ERROR: failed to create lock directory ‘/home/me/src/Rlibs/00LOCK-Rcpp’
...

由于我的计算机位于计算机集群上，因此我已在不同的节点上进行了尝试，并且小心删除了在/tmp中下载的临时文件.奇怪的是我有权在/home/me/src/Rlibs/中编写.所以我的问题是:

As my machine is on a computer cluster, I've tried it on different nodes, and I was careful to delete the temporary files downloaded in /tmp. What is strange is that I have rights to write in /home/me/src/Rlibs/. So my questions are:

1. 为什么R只想在/home/me/中拥有写权限，而又想在/home中具有写权限?
2. 如何解决该错误?

推荐答案

在NFS文件系统上，有时需要关闭哪些内容并不明显.

On NFS file systems it is sometimes not obvious what things you have to close.

避免这种情况的最佳方法是在命令行上使用--no-lock参数，即:

The best way to avoid this is to use the --no-lock argument on the command line, i.e.:

R CMD INSTALL --no-lock <pkg>

在R中，您可以使用以下命令在命令中进行操作:

From within R, you can do this from within your command using:

install.packages("Rcpp", dependencies = TRUE, INSTALL_opts = '--no-lock')
