Hi YiHui,

I have tried to update the package xfun for some times but not successful. Here is the log of the program in the console:

> install.packages('xfun')
trying URL 'https://cran.rstudio.com/bin/windows/contrib/4.0/xfun_0.22.zip'
Content type 'application/zip' length 327581 bytes (319 KB)

package ‘xfun’ successfully unpacked and MD5 sums checked
Warning in install.packages :
  cannot remove prior installation of package ‘xfun’
Warning in install.packages :

Warning in install.packages :
  restored ‘xfun’

The downloaded binary packages are in
    C:\Users\user\AppData\Local\Temp\RtmpSmXztt\downloaded_packages

I came to the folder but found the dll file remain the same.


OS: Windows 10.
R version: 4.0.4.
RStudio: 1.4.1103
Can you please show me how to fix this?

Thank you very much

On windows, updating package with source code can be tricky because of the dll issue.

You need to be sure to use a clean session, with nothing loaded and even outside of RStudio - this is to avoid having xfun package loaded in anyway in your session or in another session. This is a known constraint on windows

That is why I advice now to you use the new pak package which greatly improve this experience on Windows: It will detect any other sessions where a package could be loaded and could cause a dll lock issue.

See https://pak.r-lib.org/

Can you try :

install.packages("pak", repos = "https://r-lib.github.io/p/pak/dev/")
pak::pak("xfun")

If you don't want to use pak

Be sure to close all R sessions.
Open R (without RStudio if possible)
run install.packages("xfun") in this clean session

Hope it helps

hi @cderv , I just know about pak by your reply and have opened the link to the pak page. It's interesting. I would try tomorrow to see if I can fix the installation myself. Thank you very much
