Download of package ‘terra’ failed

Hi. I have problems downloading the terra package. The message is:

Warning in install.packages :
downloaded length 54617208 != reported length 96919656
Warning in install.packages :
URL 'https://cran.rstudio.com/bin/macosx/contrib/4.1/terra_1.4-22.tgz': Timeout of 60 seconds was reached
Error in download.file(url, destfile, method, mode = "wb", ...) :
download from 'https://cran.rstudio.com/bin/macosx/contrib/4.1/terra_1.4-22.tgz' failed
Warning in install.packages :
download of package ‘terra’ failed

I already close all files on my RStudio hoping that it would be solved but the issue remains the same.

I am waiting for any helps toward this.
Thank you.

Check the GitHub infomation.

If you have Windows you need first install RTools. You need the "raster" , "Rcpp" and "
remotes" packages. Next install "terra" from github.

Sys.setenv("R_REMOTES_NO_ERRORS_FROM_WARNINGS" = "true")
remotes::install_github("rspatial/terra")

I tried this but it doesn't solve. Do you have any solutions?

This seems like a connectivity issue, R is not being able to complete the download from the CRAN repository you have selected, these are some things to try.

  • Choose a different CRAN repository, RStudios repository is a good choice (http://cran.rstudio.com/) or you could choose one that is geographically closer to you.

  • Disable secure download setting.

  • Check if your internet connection has traffic restrictions of some kind, like a firewall, proxy server, etc. This is usually the case when you are at work or school.

I already changed my CRAN repository to my country's but I still face the same problem. Also, I already checked my internet and it is good since I check the connection on both laptop and phone but the package cannot be downloaded.

Check this other problems:

May be update GDAL/PROJ.

But is very extranger this problem.
I think that you need update all the librarys or try whit RCloud.

@M_AcostaCH, in this case the installation process never actually starts because the download fails so the issues you are referencing are not relevant to this situation, or at least not yet.
