[GRASS-user] GRASS Environment Variables

[Joseph Kariuki]

Hi Andres, I have run the code in pycharm but still raises an error

/usr/bin/python2.7 /home/hempire/PycharmProjects/GRASS/ingrass.py
> Traceback (most recent call last):

However on terminal it executes with no errors. I will stick to using
terminal. PyCharm is limiting.
