[英]Weasyprint get undefined property at invoking write_pdf: "AttributeError: 'PosixPath' object has no attribute 'read_text'"
I'm running weasyprint project on ubuntu 18.04 and I try to create aa pdf.我在 ubuntu 18.04 上运行 weasyprint 项目,并尝试创建 aa pdf。
The problem started when I try to set a footer image.当我尝试设置页脚图像时,问题就开始了。 I'm running on python 3.6.7
我在 python 3.6.7 上运行
This is my code invoking weasyprint:这是我调用 weasyprint 的代码:
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:但后来我收到以下错误:
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

I solve the problem after some help here: https://github.com/Kozea/WeasyPrint/issues/807 我在这里获得一些帮助后解决了这个问题: https : //github.com/Kozea/WeasyPrint/issues/807
The problem resume below: 问题在下面恢复:
In my pyhton project I got a requiriments.txt and I put
pathlib
as requirement.在我的pyhton项目中,我得到了requiriments.txt,并将
pathlib
作为要求。 Somehow this pathlib overrides the current lib installed althogether python 3.5 or higher.以某种方式,该pathlib会覆盖安装了python 3.5或更高版本的当前lib。 When I remove this dependencie the problem is solved.
当我消除这种依赖性时,问题就解决了。
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.我在尝试通过
pip install
安装包时遇到了同样的错误,但我的项目中确实需要 pathlib,所以我不能简单地删除依赖项。
I found the solution here我在这里找到了解决方案
Basically, you have to run pip3
instead of pip
基本上,你必须运行
pip3
而不是pip
