Windows 7，update.packages问题:“无法移动临时安装"? [英] Windows 7, update.packages problem: "unable to move temporary installation"?

问题描述

在将用户的全部权限授予R文件夹之后，我正在Windows 7上使用R 2.13.0(如

I am using R 2.13.0 with windows 7, after giving my user full privileges to the R folder (as described here). This allows me to install new packages just fine.

但是，当使用update.packages()更新现有软件包时，我不断收到以下错误消息(例如，更新MASS软件包时):

However, when using update.packages(), to update existing packages, I keep getting the following error (for example, when updating the MASS package):

'MASS'包已成功解压并检查了MD5的总和

package 'MASS' successfully unpacked and MD5 sums checked

警告:无法移动临时安装 'C:\ Program Files \ R \ R-2.13.0 \ library \ file6cae3bcf \ MASS' 到'C:\ Program Files \ R \ R-2.13.0 \ library \ MASS'

Warning: unable to move temporary installation 'C:\Program Files\R\R-2.13.0\library\file6cae3bcf\MASS' to 'C:\Program Files\R\R-2.13.0\library\MASS'

关于如何解决此问题的任何建议?

Any suggestions on how to fix this?

p.s:以管理员身份运行R或将库位置移出程序文件"不是解决方案(这是hack，但我正在寻找解决方案)

p.s: Running R as an administrator or shifting the library location out of Program Files is not a solution (it's a hack - but I am looking for a solution)

推荐答案

我发现问题确实出在防病毒实时文件系统保护"上.我执行以下操作来解决该问题:

I found that the problem indeed is the antivirus "real time file system protection". I do the following to fix the problem:

trace(utils:::unpackPkgZip, edit=TRUE)

我编辑第140行(R 3.4.4中的第142行):

I edit line 140 (line 142 in R 3.4.4):

Sys.sleep(0.5)

收件人:

Sys.sleep(2)

我似乎杀毒软件停止了软件包tmp dir的创建.将其更改为2秒后，错误消失了.

I seems like the antivirus stalls the creation of the package tmp dir. After changing it to 2 seconds the error is gone.

要以编程方式执行

trace(utils:::unpackPkgZip, quote(Sys.sleep(2)), at = which(grepl("Sys.sleep", body(utils:::unpackPkgZip), fixed = TRUE)))
