Problems installing reportlab module: 'No module named future_buildins'

[nealtz]

I want to generate PDFs from SQLite output and found the ReportLab Toolkit. A search let me found this thread: Other ways to convert Markdown/HTML to PDF in iOS where hvmhvm wrote that he installed the reportlab module in Editorial. I thought this must also be possible with Pythonista and installed the module with the help from pipista and shellista.

Then I tried to run the example script from the documentation:

Edit: ! This testscript got messed up !

import pipista
from reportlab.pdfgen import canvas

def hello(c):
  c.drawString(100,100,"Hello World")

c = canvas.Canvas("hello.pdf")
c.showPage()
hello(c)

In line 2 I got an 'ImportError: No module named future_buildins'

I can't find a way to install the future_builtins module.

Has anyone an idea how I can get reportlab working?

I now realized that the user hvmhvm installed Version 2.7 of the reportlab module while I installed the actual Version 3.1.8. After I deleted Version 3.1.8 and installed Version 2.7 the testscript runs without any errormessages. But I can't find the 'hello.pdf' file that should be saved by the script.

Aaaargh!

I don't know how it happend, but somehow my testscript got messed up. It should be:

import pipista
from reportlab.pdfgen import canvas

def hello(c):
  c.drawString(100,100,"Hello World")

c = canvas.Canvas("hello.pdf")
hello(c)
c.showPage()
c.save()

This script works with the 2.7 Version of reportlab and creates the 'hello.pdf' file ... :-) !
