#80024 — Implementing pdfkit and wkhtmltopdf on windows fails

I am able to install both of these packages on my mac at home and it works well.

I am trying to install on windows 7 at work and it fails.  PDFKit is trying to find the wkh package and it cannot. I have entered the full path to the exe for the environment variables and the error below is spit out.

If I explicitly cd into the directory that has the executable the script works fine

>>> import os
>>> path='C:\\wkhtmltopdf\\bin\\'
>>> os.chdir(path)
>>> pdfkit.from_string('Hello!', 'out.pdf')
Loading pages (1/6)     #this works after cd into the exe directory


Where can I specify the path to the executable?

I don't know your particular module, but generally, you want modules 
installed on your sys.path.  Either install it there, or add the 
directory to sys.path (which is a list)

I'd suggest doing the latter, then figure whether a reinstall is called 
for.  It looks like you installed it in the root directory of C:, rather 
than in the site-packages.

I see the problem.  The installation of the package did not drop down the files that the executable is looking for.

Thanks

Following the link in the traceback I find the installation instruction for 
windows:

"""
Download the installer from the wkhtmltopdf downloads list and add folder 
with wkhtmltopdf binary to PATH.
"""

This PATH has nothing to do with Python's sys.path which specifies where 
Python looks for modules, and you have to set it according to the rules of 
your OS, e. g.

http://geekswithblogs.net/renso/archive/2009/10/21/how-to-set-the-windows-path-in-windows-7.aspx

Once you have added "the directory you had to cd into" follwing the above 
instructions your script should work in a newly opened shell window.
