"Reportlab Version 2.1+ is needed!" --import error

[mcc...@gmail.com]

Hi, 

I'm using working on a django / mezzanine / cartridge project.  The author of cartridge thought it might be a problem with the Pisa library.  Any suggestions? Thanks! 

When I try to generate a PDF of an invoice, I receive this error:

"Reportlab Version 2.1+ is needed!"

I have Reportlab 3.0 installed.

I'm working in a clean virtualenv. This is my pip freeze:

Cartridge==0.9.2
Django==1.6.2
Mezzanine==3.0.9
PIL==1.1.7

Do you have a full traceback?

The problem is with the installation.

The __init__ checks for a variable REPORTLAB22. This is imported from util.py.

The code in util.py is using the following logic

if not (reportlab.Version[0] == "2" and reportlab.Version[2] >= "1"):

  raise ImportError("Reportlab Version 2.1+ is needed!")

REPORTLAB22 = (reportlab.Version[0] == "2" and reportlab.Version[2] >= "2")

This will fail as the reportlab version is now 3.0.

Just replace this code segment with the following:

if not (reportlab.Version[:3]>="2.1"):

  raise ImportError("Reportlab Version 2.1+ is needed!")

REPORTLAB22 = (reportlab.Version[:3]>="2.1")

and reinstall xhtml2pdf. It will work.

You will need to uninstall xhtml2pdf first.

I am new to google groups and thus, pardon is I have not followed some norms.

That worked.  Thank you for your help! 

fyi: for anyone who happens on this post:  I actually am using the older  Pisa 3.033 package, and I went in and changed it to your code.  

My folders are as follows:  /ENV2/lib/python2.7/site-packages/sx/pisa3/pisa_util.py

Had a similar problem And applied the suggested patch anyhow assuming that the reportlab version was the issue, but did not get the error message but same line fail

However I'm trying to run Python 3 I think that Pisa may not be P3 usable??

Getting: 

Exception Value:	invalid syntax (__init__.py, line 43)
Exception Location:	/home/tom/myvenv3/lib/python3.3/site-packages/ho/pisa/__init__.py in <module>, line 26
