[GRASS-user] grass installation on ubuntu/server

group,
I believe i installed grass70 on my server as the main interface comes up when i issue “grass70”. However, when i execute a python-grass code, the response is …
ERROR: ERROR: Please install the GRASS GIS development package

ERROR: Cannot find GRASS GIS 7 start script (grass70 --config path)
Your suggestion is appreciated.
