Replying to Faraslis:

nul=open <os.devnull, 'w'>
IOerror: [Errno 2] No such file or directory : 'nul'

@devs, for the record:

grep -n 'nul = open' ./lib/init/ 
409:            nul = open(os.devnull, 'w')
540:            nul = open(os.devnull, 'w')
1184:    nul = open(os.devnull, 'w')

Replying to neteler:

nul=open <os.devnull, 'w'>
IOerror: [Errno 2] No such file or directory : 'nul'

Apparently, it's possible for the service implementing the null device ('nul' pseudo-file) to be stopped or to malfunction.

The status can be checked via the control panel. Start the Device Manager (Control Panel > Hardware and Sound > Device Manager), select View > Show hidden devices, then under Non-Plug and Play Drivers, there should be an entry for "Null".

The corresponding registry key is


The Start and Type values should both be 1.

Does the problem persist with RC1?

Actually, I also experienced this bug on a win7 64bit notebook. I tried winGRASS beta3, RC1 earlier and today (23rd Feb) the stable 7.0.0 version. The 'Null' entry in Plug and Play Drivers and values in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Null were also checked and everything looked ok.
