Describe the bug I have sethrfore/r-srfs R installed and would like to keep it, but the formula for grass gives me the following error:

Error: r is already installed from sethrfore/r-srf!
Please `brew uninstall r` first."

As far as know, R is not e dependency of grass, wherefore the dependency of r which is here https://github.com/OSGeo/homebrew-osgeo4mac/blob/e3b64237d09f180abe3d2860da71161d1027134d/Formula/osgeo-grass.rb#L94 should be made optional?

as additional info, all other dependencies are installed:

If it is the case that you can change the shebang at the beginning of
the script to enforce Python 2 usage.

  #!/usr/bin/env python

Should be changed into

  #!/usr/bin/env python2

Hi @jctull , not sure why your links are dead. This is the OSgeo4mac website which contains the info about the R dependency installation. I hope it can help you.

@alazarolop Thanks -that should help.

But I am trying to install grass, and I do not think that R is a requirement to run grass. So R should be an optional dependency.

Hi @alazarolop but this was not my issue.

@rkrug You can try to build osgeo-grass from source without the R dependency. As noted in the link above, osgeo will not work with the version of R you have installed.

brew install --build-from-source --without-r osgeo-grass

[rkrug]

This option does not exist in osgeo-grass, only in QGIS.

So - I think it should be added to osgeo-grass, as grass does not need R, even though without doubt, very useful.

[alazarolop]

@rkrug I reckon the reason why the R dependency is there is because you can launch a R session from within GRASS. Could you solve the issue with the guide?

I do agree it should be added a flag option as long as there is no conflict with other formulas.

[rkrug]

@alazarolop if you are referring to this guide this QGIS Guide, than it surely will help, but I did not try it, as I would prefer not to play around at that level if not necessary (which it is not at the moment)

Ao yes - please add the flag option --without-R in the grass formula! If there is a formula which depends on GRASS installing R, that there is a problem in that formula, as R should be optional for grass.
