This issue should be solved with winGRASS 7.8.5-2 standalone installer.

First I think you are mixing up running GRASS commands in python, versus
the  command prompt.
You do not necessarily need python (nor Anaconda) to run GRASS.  Everything
can be done from the command prompt or using the GRASS GUI. Furthermore,
it's a good idea, in my opinion, to begin learning the GRASS modules by
running commands at the command prompt, then once you have the details
worked out, shift to writing python scripts.

Here, clearly you did not specify the full file name to the ASTER DEM file.
Probably the ".TIF" extension is missing? Can you check and enter the full
file name, then get back to the list if you encounter any more problems.

I want solutions where I can run GRASS GIS directly from the command line

[GRASS-user] Using Python in GRASS GIS for analysis

2021-02-02 Thread Omkar Kadlag 
Hello Sir/Ma'am,

Warm Greetings.

I am Omkar Kadlag from Mumbai,India.I am pursuing Electronics and
Telecommunication Engineering majors from K.J.Somaiya Institute of
Engineering and Information Technology,Mumbai. I am working on a project
"Watershed Analysis using python".

While using GRASS GIS python console for analysis, I'm unable to get
desired results. While giving the input ( as a DEM tile ) in the PowerShell
prompt of GRASS GIS Software, it gives an error, as 'wxpython file' is not
available.

Error -

Starting GRASS GIS...
Traceback (most recent call last):
  File "C:\Program Files\GRASS GIS 7.8\gui\wxpython\gis_set.py", line 43,
in 
from core.gcmd import GMessage, GError, DecodeString, RunCommand

please report this error to the GRASS developers.
On systems with package manager, make sure you have the right GUI package,
probably named grass-gui, installed.
To run GRASS GIS in text mode use the --text flag.
Use '--help' for further options
 grass78 --help
See also: https://grass.osgeo.org/grass78/manuals/helptext.html
Exiting...
Press any key to continue . . .

Then I made a new environment in the anaconda prompt, where I installed
'wxpython' and was successfully able to run GRASS GIS software, but now the
issue is I can't use the command prompt for my analysis. Then I tried to
give inputs in the anaconda command prompt but was still unable to get
correct outputs.

Hello Omkar,
if you want to get any answer, include errors as a text in the body of
your email instead of images. Just select the error in your console
and paste into email.

Good luck,
