As said: We have this issue on two computers, where R version 4.0.4 does not work with Gurobi 9.1.2. Our institute works since two years with Gurobi, and previous installations were fine. Although the insatllation throws a warning, the gurobi package is NOT installed. Details:

R.version

platform x86_64-w64-mingw32
arch x86_64
os mingw32
system x86_64, mingw32
status

minor 0.4
year 2021

Warning in install.packages : package ‘C:/gurobi912/win64/R/gurobi_9.1-2’ is not available for this version of R

A version of this package for your version of R might be available elsewhere, see the ideas at https://cran.r-project.org/doc/manuals/r-patched/R-admin.html#Installing-packages

  Hi Christoph,

  I take it that setting repos=NULL in the installation command fixes the issue, as indicated by your comment in the corresponding Stackoverflow post.

  Please let us know if there are further issues.

  Cheers,
  Matthias
