<p class="MsoNormal"><span lang="EN-US">Hi all – I am trying out the grass-session package for the first time and am having issues with the GRASSBIN environment variable. It looks like the grass-session I was able to download references grass75svn.bat. I’m
onto grass76. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I was able to get around this in a python session with os.environ[‘GRASSBIN’]=D:\<mypath>\grass76.bat, but it’d be nice to not have to do that.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">If I run “set GRASS” from the command line, I see that GRASSBIN=D:\<mypath>\grass75svn.bat even GRASS_VERSION=7.6.1<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Where is the GRASSBIN variable set? I’ve been looking around and can’t seem to find it.<o:p></o:p></span></p>
