Weasyprint get undefined property at invoking write_pdf: "AttributeError: 'PosixPath' object has no attribute 'read_text'"

Question

I'm running weasyprint project on ubuntu 18.04 and I try to create aa pdf.

The problem started when I try to set a footer image. I'm running on python 3.6.7

This is my code invoking weasyprint:

import sys
import os
from weasyprint import HTML, CSS

htmlFile = sys.argv[1]
pdfFile = sys.argv[2]

html = HTML(filename=htmlFile)

css = CSS(string='@page { @bottom-center { width: 125%; margin-top: 10px; content: " "; background-image: url(file://' + os.getcwd() + '/pdf/footer.png); background-repeat: no-repeat; background-position: right;  background-size: 100%; } }')

html.write_pdf(pdfFile, stylesheets=[css])

But then I got following error:

Error: Command failed: python3 /node_modules/my-project/python/run.py /node_modules/my-project/pdf/catalog_01e299a3-1fca-482b-a512-e1bea832559f.html /node_modules/my-project/pdf/catalog_01e299a3-1fca-482b-a512-e1bea832559f.pdf

Answer 1

I solve the problem after some help here: https://github.com/Kozea/WeasyPrint/issues/807

The problem resume below:

In my pyhton project I got a requiriments.txt and I put pathlib as requirement. Somehow this pathlib overrides the current lib installed althogether python 3.5 or higher. When I remove this dependencie the problem is solved.

Answer 2

I had this same error while trying to install a package through pip install , but I did need pathlib in my project, so I couldn't simply remove the dependency.

I found the solution here

Basically, you have to run pip3 instead of pip
