Question

{solved}: PHP exec() problem with custom Python module

Answer 1

+1 A:

Should you be doing

exec("/usr/bin/python /usr/lib/python2.4/site-packages/MyModule/myModule script.py -v pixfx.xml 2>&1", $output, $return);

OR

exec("/usr/bin/python/python /usr/lib/python2.4/site-packages/MyModule/myModule script.py -v pixfx.xml 2>&1", $output, $return);

Should not be doing?

ircmaxell 2010-08-23 15:18:08

sorry, Should you be doing*

RobertPitt 2010-08-23 15:20:39

thanks, that worked.

ssdesign 2010-08-23 15:32:48

ok I ran into another bug after I got the exec() to work.I have the module installed correctly, still I get following error:************ Traceback (most recent call last): File "/usr/lib/python2.4/site-packages/MyModule/myModulw/script.py", line 60, in ? from myModule.ttLib import TTFont ImportError: No module named myModule.ttLib**************Any idea?

ssdesign 2010-08-23 15:50:54

you would have to show the source of `script.py` and it loks like it cant import some fonts, im not that good at Python but if you post your code ill take a look

RobertPitt 2010-08-23 22:14:29

The script itself is about generating fonts. Thats why you see things like "TTFont" etc. These are module names :)

ssdesign 2010-08-24 02:57:42

uts not the modules causing the script, its a parser error, witch to fix we need the source code of the .py

RobertPitt 2010-08-24 07:19:08

Hi,THis is how the .py script looks like:**************** #! /usr/bin/env pythonimport sysimport osimport getoptimport refrom fontTools.ttLib import TTFontfrom fontTools.ttLib.tables.otBase import OTLOffsetOverflowErrorfrom fontTools.ttLib.tables.otTables import fixLookupOverFlows, fixSubTableOverFlowsfrom fontTools.misc.macCreatorType import getMacCreatorAndTypefrom fontTools import version************************************ I have removed all the comments.... so the line 60 is "from fontTools.ttLib import TTFont"

ssdesign 2010-08-24 09:20:37

to add to my previous comment: TTFont is a "class" defined in a file called __init__.py inside a folder called "ttLib" which is again inside a folder called "fontTools".

ssdesign 2010-08-24 09:24:20

that was supposed to be two underscores before and after 'init' :)

ssdesign 2010-08-24 09:25:15

can you append it to your OP please and wrap it in some code tags

RobertPitt 2010-08-24 09:35:30

appended the code

ssdesign 2010-08-24 12:49:44

are you sure that 'fontTools.ttLib' contains the module 'TTFont' ? the library seems to exists but within the library the module is failing, try re downloading the module.

RobertPitt 2010-08-24 13:36:08

yes TTFont is a class defined inside a python file called (doubleunderscore)init(doubleunderscore).py............ this file resides inside a folder called ttLib, which is inside a foler called fontTools (where my python script is).

ssdesign 2010-08-24 13:45:56

your best bet is to make a new Post and ask specifically about this issue, i understand the structure of pythen but thats as far as i go, sorry mate.

RobertPitt 2010-08-24 14:14:55

I just did help('modules') in SSH and the list returned does not contain FontTools.... how come? Does it mean the module is not installed and it is just residing in site-packages?

ssdesign 2010-08-24 14:22:15

i would think so, http://docs.python.org/distutils/apiref.html#module-distutils.command.register

Answer 2

A:

You might find it useful to debug under the user that php is running under, ie www-data, apache, etc. This is helpful for uncovering any permission, path or environment issues that may arise.

Dana the Sane 2010-08-23 18:40:27

Hi, how to debug under user?
