[sipriusPT]

I am trying to use pdfkit library, one folder with permissions to write, and have also trying in root, who is in this case C:\, for example,

pdfkit.from_string('Hello!','out.pdf')

but dont know how to use it, because no matter what I do, I am always get:

Error:

During handling of the above exception, another exception occurred:

If this file exists please check that this process can read it. Otherwise please install wkhtmltopdf - https://github.com/JazzCore/python-pdf

I have even created an empty out.pdf file, and in another attempt, add also the complete path, but still same error.

Otherwise please install wkhtmltopdf

Install wkhtmltopdf.
Add C:\Program Files\wkhtmltopdf\bin to Environment Variables Path.

I was trying to do this only through python 3 but its turning into a struggle.

I will have to use that pre compiled version with subprocess as a workaround only from html to pdf.

Thanks anyway snippsat!

# pd_kit.py
import pdfkit

pdfkit.from_file('test.html', 'out_html.pdf')
pdfkit.from_string('Hello!', 'out.pdf')

Test run,from command line not editor.

Both pdf file works.

Test Windows Paths.

E:\div_code
λ python -V
Python 3.7.3

E:\div_code
λ pip -V
pip 19.2.3 from c:\python37\lib\site-packages\pip (python 3.7)

E:\div_code
λ wkhtmltopdf -V
wkhtmltopdf 0.12.5 (with patched qt)

E:\div_code
λ wkhtmltoimage -V
wkhtmltoimage 0.12.5 (with patched qt)

This is how it how it should look when works,
see that Path work dos not matter which folder you use if set correct in Environment Variables Path.
