[GRASS-user] error in g.extension while installing i.fusion.hpf in windows

that's the reason of g.extension failing

downloading the zip-file (see link above) and copying the files into the corresponding folders in

C:\Users\YourUserName\AppData\Roaming\GRASS7\addons\

should help.

now tested in this way:

g.region -p -a raster=lsat7_2002_80@PERMANENT align=lsat7_2002_80@PERMANENT

i.fusion.hpf pan=lsat7_2002_80@PERMANENT msx=lsat7_2002_10@PERMANENT,lsat7_2002_20@PERMANENT,lsat7_2002_30@PERMANENT,lsat7_2002_40@PERMANENT suffix=_hpf

Thanks both!

So the solution in the meantime is to:

  1. download the zip file from https://wingrass.fsv.cvut.cz/grass78/x86_64/addons/latest/
  2. unzip and remove the pychache folder
  3. copy everything to C:\Users\YourUserName\AppData\Roaming\GRASS7\addons\

Is that correct?

I hope the g.extension problem can be fixed soon? @Helli would you mind opening an issue for that, please?

Cheers,
Vero

yes; the contents of following folders

D:\dl\i.fusion.hpf>dir /b
bin
docs
etc
scripts

into the corresponding folders in C:\Users\YourUserName\AppData\Roaming\GRASS7\addons\

@Helli would you mind opening an issue for that, please?
