Hi, Me and an office colleague on Microsoft Windows 10 PCs are having difficulty installing any package. This is a recent issue for us, and we suspect our McAfee antivirus has modified by our IT department. Let's take, for example, install.packages("mypackage"), here is the output:
package ‘mypackage’ successfully unpacked and MD5 sums checked Warning in install.packages : unable to move temporary installation ‘C:\Users\mtoews\Documents\R\win-library\3.3\file382064842da2\mypackage’ to ‘C:\Users\mtoews\Documents\R\win-library\3.3\mypackage’ Debugging, I found the issue around here: https://github.com/wch/r-source/blob/980c15af89d99c04e09a40708512a57c49d1c6ee/src/library/utils/R/windows/install.packages.R#L173-L174 > ## To avoid anti-virus interference, wait a little > Sys.sleep(0.5) As indicated by an answer (https://stackoverflow.com/a/44256437/327026), debugging slows down the function to allow the package to be installed. A simple fix is to increase the sleep time to a time that is longer than 0.5 seconds. (I've tried testing new times, but I can't seem to overload this function). Or use a different strategy, such as using a few attempts with increasing wait times, or using a custom unlink function. Happy to help out or test more on this issue. Also, if any R Core member could add me to R's Bugzilla members, that would be convenient for me.
