Download PDF generates Import Error: Reportlab Version 2.1+ is needed!

[mcchan1]

Hi,

I'm a Django noob, and I'm generally out of my league when it comes to dependency issues. Thanks in advance for your help!

When I try to generate a PDF of the 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
Drum==0.1.2
Mezzanine==3.0.9
PIL==1.1.7
Pillow==2.3.0
bleach==1.4
feedparser==5.1.3
filebrowser-safe==0.3.2
future==0.9.0
grappelli-safe==0.3.6
html5lib==1.0b3
oauthlib==0.6.1
pisa==3.0.33
pyPdf==1.13
pytz==2013.9
reportlab==3.0
requests==2.2.1
requests-oauthlib==0.4.0
six==1.5.2
sphinx-me==0.2.1
tzlocal==1.0
wsgiref==0.1.2
xhtml2pdf==0.0.5

That error doesn't come from cartridge. My best guess is the pisa lib that uses it for generating pdfs, suggest chasing it up with that project:

https://pypi.python.org/pypi/pisa/3.0.33

Thanks. As suggested, I was able to find the help I needed on the "xhtml2pdf" googlegroup mailing list.

FYI: I went into ./lib/python2.7/site-packages/sx/pisa3/pisa_util.py to implement this solution:

"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")

Option 1 :

Remove below in your requirements.txt file
pisa==x.x.xx

and add:

-e git+https://github.com/rajanmandanka/pisa.git#egg=pisa

Option 2:

1. uninstall pisa
   pip uninstall pisa
2. install pisa using pip
   pip install git+https://github.com/rajanmandanka/pisa.git

Could you elaborate a bit? Which versions of Python / Django / Mezzanine
/ Cartridge are you using? Can you provide a reproducible test case?
