[GRASS-user] OSError importing CSV file with a Python Script

GRASS GRASS user

Hi everyone!

I am trying to wrote a Python Script for importing CSV files to GRASS GIS without start GRASS. But I am getting a OSError:

import grass.script as g
g.run_command(“db.in.ogr”, dsn=“table.csv”, output=“test”)
Traceback (most recent call last):
File “”, line 1, in
File “/usr/lib/grass64/etc/python/grass/script/core.py”, line 189, in run_command
ps = start_command(*args, **kwargs)
File “/usr/lib/grass64/etc/python/grass/script/core.py”, line 177, in start_command
return Popen(args, **popts)
File “/usr/lib/grass64/etc/python/grass/script/core.py”, line 56, in init
startupinfo, creationflags)
File “/usr/lib/python2.7/subprocess.py”, line 679, in init
errread, errwrite)
File “/usr/lib/python2.7/subprocess.py”, line 1249, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory

I attached a IPython Notebook example (print version https://dl.dropbox.com/u/473460/import_table_test.html). The command works fine in GRASS console, GRASS Python console and the script executed inside GRASS.

Any help?

Did you check this section about setting the right variables?

Thanks! It's works! I have wrong the PATH variable defined. This are my definitions in .bashrc:

export GISBASE="/usr/lib/grass64"
#export PATH="$PATH:$GISBASE/bin:$GISBASE/script:$GISBASE/lib" # wrong!!!
export PATH="$PATH:$GISBASE/bin:$GISBASE/scripts"
export PYTHONPATH="${PYTHONPATH}:$GISBASE/etc/python/"
export PYTHONPATH="${PYTHONPATH}:$GISBASE/etc/python/grass"
export PYTHONPATH="${PYTHONPATH}:$GISBASE/etc/python/grass/script"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$GISBASE/lib"
export GIS_LOCK=$$
export GISRC="$HOME/.grassrc6"
