My enviroment:
--
Slackware Linux 10.2
Python 2.4.2
MySql version 4.1.14
MySql-Python 1.2.0
What I am trying to do:
---
Using MySQL, Python, My-Sql-Python module and CGI create a simple
database that can be accesed with a webpage.
Everything worked great up to this error when trying to load the
webpage:
ImportError: No module name MySQLdb
Note that I do NOT get the error when running the script normally from
Python.
So I'd say it has something to do with sys.path
Is there anything non-standard with your config ? Like modules
installed as a user and/or outside of /usr/lib/pythonXXX/site-packages/ ?
I have read much but can not seem to nail the problem down, I am
thinking a path error.
+1
add this at the beginning of your script, *before* trying to import
anything else.
import sys
print sys.path is, sys.path

Normally when you install MySQLdb it will install inside the site-packages directory, and so would be available to scripts whether they were run from a command line or a web CGI script. I therefore suspect you need to repeat the installation of MySQLdb on your server machine. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC www.holdenweb.com PyCon TX 2006 www.python.org/pycon/ -- http://mail.python.org/mailman/listinfo/python-list
Re: ImportError: No module name MySQLdb
Re-reading my message I noticed a stupid error, not effecting my problem but annoying, I assigned variables and then did not use them, then included import cgi for my regular script. This is how the command line script should look: #!/usr/bin/python import MySQLdb db=MySQLdb.connect(host = '192.168.0.112', db = 'phone') cursor=db.cursor() cursor.execute(Select * from phone) result = cursor.fetchall() for record in result: print record[0],record[1],record[2] -- http://mail.python.org/mailman/listinfo/python-list
Re: ImportError: No module name MySQLdb
This is the result of print sys.path: print sys.path ['', '/usr/local/lib/python24.zip', '/usr/local/lib/python2.4', '/usr/local/lib/python2.4/plat-linux2', '/usr/local/lib/python2.4/lib-tk', '/usr/local/lib/python2.4/lib-dynload', '/usr/local/lib/python2.4/site-packages'] MySQLdb lives here but is not in the path: /usr/local/lib/python2.4/site-packages/MySQLdb Everything is running on the same machine here in my house, everything was installed and is launched as root.

Re: ImportError: No module name MySQLdb
From what I can tell everything seems right. Here are the results of the sys.path: print sys.path ['', '/usr/local/lib/python24.zip', '/usr/local/lib/python2.4', '/usr/local/lib/python2.4/plat-linux2', '/usr/local/lib/python2.4/lib-tk', '/usr/local/lib/python2.4/lib-dynload', '/usr/local/lib/python2.4/site-packages'] MySQLdb lives here: /usr/local/lib/python2.4/site-packages/MySQLdb but is not in the path I installed and am trying to run everything as root, and it is all on the same computer right here with me. If I can ever get this simplistic problem solved maybe you guys can help me to get Zope running, it is not cooperating either... :-) Fred -- http://mail.python.org/mailman/listinfo/python-list

Bad header=['/var/www/cgi-bin', '/usr/lib: /var/www/cgi-bin/mysqld_script_test.py I think you can ignore this error: it's happening because of your debug output of syst.path, which presumably takes place before the script prints out Content-Type: text/html or similar. If your program doesn't do that it'll likely not produce what you expect anyway. Finally, you might want to think about adding import cgitb; cgitb.enable() to your existing scripts. This will give you a much more acceptable traceback from web conditions. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC www.holdenweb.com PyCon TX 2006 www.python.org/pycon/ -- http://mail.python.org/mailman/listinfo/python-list

Everything worked great up to this error when trying to load the webpage: ImportError: No module name MySQLdb Some suggestions: Start python interactively and try import MySQLdb. Stuff in a subdirectory to site-packages are normally available. If this doesn't work, it seems something is fishy with your MySQLdb install, provided you are using it right. There might be an __init__.py missing or something, but this is a mature product which ought to have a stable install procedure. If things work interactively, but not in the CGI script, you might want to add import sys print sys.path to your CGI script and see what that gives you. Finally, the cgitb module is pretty useful.

Re: ImportError: No module name MySQLdb
I have discovered the possible problem (I can't check this until later when I am home) I think when I upgraded to Python 2.4.2 it created my problem. Below is what is going on: Default Slackware 10.2 install - 2.4.1 installed into /usr/lib/python2.4 Python 2.4.1 upgraded to 2.4.2 Upgrade downloaded from Python.org compiled and installed - 2.4.2 installed into /usr/local/lib/python2.4 Bin files are in: /usr/bin/python and /usr/local/bin/python MySQLdb instatlled after the 2.4.2 upgrade works fine at the command line I am betting that when I launch the script from the webpage it is looking for /usr/bin/python I should be able to make a symlink in /usr/bin/python -- /usr/local/bin/python And of course change #!/usr/bin/python to #!/usr/local/bin/python in the script What do you think?

Re: ImportError: No module name MySQLdb
Fixed... All I did was change #!/usr/bin/python to #!/usr/local/bin/python The page loaded right up it was loading Python ver 2.4.1 rather than 2.4.2 where the MySQL db module was installed... I knew it would be something easy... I learned something so it was worth it... -- http://mail.python.org/mailman/listinfo/python-list
