"unable to move temporary installation" when installing dependency packages in R

Question

When I install a package, the prerequisite packages were installed first before the actual package. I get the "unable to move temporary installation" warning for all the prerequisite packages, but no such warning for the actual package. But the package will give error when I load it.

For example, when I install.packages("mlr"), it installed all the dependencies and I got various warnings such as this:

package ‘BBmisc’ successfully unpacked and MD5 sums checked
Warning in install.packages :
  unable to move temporary installation ‘D:\Documents\R\win-library\3.2\filef3811142c73\BBmisc’ to ‘D:\Documents\R\win-library\3.2\BBmisc’

I ignored it because it's just a warning. Unfortunately library(mlr) gave me Error: package ‘BBmisc’ required by ‘mlr’ could not be found, so I couldn't ignore it after all.

install.packages("BBmisc") directly didn't produce the warning.

What gives? How can I work through this, short of installing all the dependencies on my own?

This problem is caused by the antivirus (most likely) as was suggested by user3710546. If you cannot disable the antivirus a workaround is to enable debugging in the package unzip function with this command:

debug(utils:::unpackPkgZip)

This will then allow you to step through the code (by pressing enter many times). This just makes the function run slower, giving the antivirus software time to complete its scanning of the new files before R wants to copy them.

I found this solution here.

Following way helped for me for windows 10: I wanted to install shiny package and was getting same error.

1. I created "shiny" folder inside /library.
2. I did setwd to this shiny folder.
3. Then triggered bellow command: install.packages("shiny",destdir="./",lib="./")
4. It still failed with the same error, but now zips were downloaded in the shiny folder.
5. There were two zips: httpuv.zip and shiny.zip
6. I extracted contents of shiny zip into shiny folder and contents of httpuv zip in httpuv folder.
7. Restarted R studio to be safe. Then triggered library(shiny) and boom, it worked like a charm..!!!
