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.
Cheers,
Mike
