Fixed the BPP version problem (by removing the appdata folder so that it would rebuild), but got " ImportError: No module named site" One example: C:\Program Files\MonetDB\MonetDB5>M5server.bat MonetDB/Python Disabled: Python 3.7 installation not found. # MonetDB 5 server v11.33.3 (Apr2019) # Serving database 'demo', using 12 threads # Compiled for x86_64-pc-winnt/64bit # Found 31.927 GiB available main-memory. # Copyright (c) 1993 - July 2008 CWI. # Copyright (c) August 2008 - 2019 MonetDB B.V., all rights reserved # Visit https://www.monetdb.org/ for further information # Listening for connection requests on mapi:monetdb://127.0.0.1:50000/ # MonetDB/GIS module loaded # MonetDB/SQL module loaded ImportError: No module named site Press any key to continue . . . Turns out the current server will not run without Python37 installed (that's a python error message). I installed Python37, but monetdb can't find the module site.py, even though it exists on my system. Directory of f:\Python37\Lib 2019-03-25 09:21 PM 22,289 site.py I have these settings for PYTHONHOME and PYTHONPATH PYTHONHOME=F:\Python37 PYTHONPATH=F:\Python37\lib I also have %PYTHONHOME% in the front of my path. It seems odd to me that python is required. I don't understand why site.py is not being found -----Original Message----- From: users-list [mailto:users-list-bounces+dann.corbit=softwareag.com@monetdb.org] On Behalf Of Sjoerd Mullender Sent: Wednesday, May 1, 2019 1:37 PM To: users-list@monetdb.org Subject: Re: BPP version problem By default, the database is in the %APPDATA% folder.
