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

在授予我的用户对 R 文件夹的完全权限后，我将 R 2.13.0 与 Windows 7 一起使用(如此处).这使我可以很好地安装新软件包.

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() 更新现有包时，我不断收到以下错误(例如，在更新 MASS 包时):

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

包'MASS'成功解包并检查MD5总和

package 'MASS' successfully unpacked and MD5 sums checked

警告:无法移动临时安装'C:程序文件RR-2.13.0libraryfile6cae3bcfMASS'到 'C:ProgramFilesRR-2.13.0libraryMASS'

Warning: unable to move temporary installation 'C:Program FilesRR-2.13.0libraryfile6cae3bcfMASS' to 'C:Program FilesRR-2.13.0libraryMASS'

关于如何解决这个问题有什么建议吗?

Any suggestions on how to fix this?

ps:以管理员身份运行 R 或将库位置移出 Program Files 不是解决方案(这是一个黑客 - 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杀毒软件的实时文件系统保护"上.我执行以下操作来解决问题:

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)

到:

Sys.sleep(2)

我似乎防病毒软件阻止了包 tmp 目录的创建.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.

以编程方式执行此操作

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