Python Installer Problem

[YoungManRiver]

All,

I downloaded the OpenEMM (Linux & Windows) to install.

The Windows version uses Python as the Installer and the programmer for this installer made some bad assumptions about the installations.

I posted a run-down of the install problems at:

http://www.openemm.org/forums/viewtopic.php?p=2101#2101

First bad assumption was that all installs would be on the "C:" drive. This prefaces and leads to all the other problems in the install code.

Second bad assumption is that this is native AMP (Apache, MySQL & PHP) install, so Reg Key in the Windows registry will look for standard naming.

My machine uses Wamp, which is successfully installed, but Wamp does not use the same key names in the Windows Registry that Apache, MySQL and PHP (AMP) use, therefore the programmer needed a list, not a single text string to use for searching in the registry. This also would apply to persons using WinAmp as their chosen AMP install tool for Windows.

I know absolutely nothing about Python, but know enough other languages (25) that I thought I would try to muddle through this to solve these problems, but right now too busy so could use some assistance.

All help here greatly appreciated!!

Thanks!!

All,

Opened a thread at:

All,

Oh wasn't talking about this Python Forum, but the official one in the link.

Here's where I'm at in my code:

You can see I had to put in:

homedrive = os.getcwd()

to get the current directory and then comment out the testing that followed as it was looking for "X:\OpenEMM" only and would not accept any other directory structure.

Anyway this gets to line 83 then blows. Says it can't find or use the agn module in

import agn

but the file is there unless it is looking for compiled version of the "agn.py" file, but this is usually not the case, but I also have the "agn.pyc" compiled file, so something is not setting right in the "path" assignments, at least that my assesment.

Any inputs or help?

All,

I guess looking for help here is a lost cause, especially when I'm the only one writing anything here.

And where is your agn module?
First search for your agn.py file and then add the found path to the Python's sys.path using

sys.path.append('[i]path to my agn-module[/i]')

P.S.:
sys.path is a list of directories where Python searches for modules.
