devhelp2qch.py: TypeError: cannot parse from 'NoneType'

I am trying to compile a devhelp book for Mac, found devhelp2qch.py script, but it gives me issues:

./devhelp2qch.py 
Traceback (most recent call last):
  File "./devhelp2qch.py", line 54, in <module>
    main()
  File "./devhelp2qch.py", line 44, in main
    in_tree = etree.parse(src_path, parser)
  File "src/lxml/etree.pyx", line 3424, in lxml.etree.parse
  File "src/lxml/parser.pxi", line 1863, in lxml.etree._parseDocument
TypeError: cannot parse from 'NoneType'

What am I missing?

You should use the Makefile, it has targets doc_html, doc_devhelp, and doc_qch.

Ouch, my bad, I should have read the readme first, sorry. I downloaded the html-book-20190110.zip and unpacked, creating reference. Now make doc_devhelp gives me:

$ make doc_devhelp
mkdir -p output
./preprocess.py --src reference --dst output/reference
Traceback (most recent call last):
  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/shutil.py", line 563, in move
    os.rename(src, real_dst)
FileNotFoundError: [Errno 2] No such file or directory: 'output/reference/upload.cppreference.com/mwiki' -> 'output/reference/common'

During handling of the above exception, another exception occurred:

You downloaded the compiled HTML book. To compile the reference yourself you need cppreference-doc-20190110.tar.xz instead, this should contain all the scripts and source HTML necessary for building (there's no need to check out this repository at all, unless you want to make changes yourself).
