Nuitka Convert Error With Weasyprint in Python Code

[himadriganguly]

I am trying to compile executable file from Python code which uses WeasyPrint for PDF conversion using Nuitka but giving error.

I have installed MinGW64 for C compiler under "c:MinGW64".

python -m nuitka --follow-imports --standalone --mingw64 websense-url-checker.py

After running the code it gives the following warning.

Nuitka:WARNING:Use '--plugin-enable=pylint-warnings' for: Understand PyLint/PyDev annotations for warnings.

It generates executable though but running the exe it gives the following.

websense-url-checker.dist\websense-url-checker.exe

Also tried with the following command.

python -m nuitka --follow-imports --show-progress --show-scons --show-modules --include-package=pyphen --include-package=tinycss2 --include-package=cairocffi --include-package=weasyprint --standalone websense-url-checker.py

But getting the following error

Sorry for the tardiness of my reaction - just recovered from severe internet outages.
Can you please provide an as small as possible snippet to reproduce this?
Ideally just the imports or similar.
Looks like the standard situation of adjusting some implicit imports and missing data files ...

[JorjMcKie]

I have looked in both your pivotal imports, tinycss2 and weasyprint. Both rely on a same-named file VERSION (no extension). These must be prersent obviously, but will not be copied without special precautions.
Even if that is once taken care of, obviously only one such file can exist in the dist folder. So you will see a wrong version for one of the packages ...

Following are the imports of python3 packages in my application

import requests
import csv
from weasyprint import HTML
from jinja2 import Environment, FileSystemLoader
from datetime import datetime
import smtplib
import configparser
from string import Template
import logging

from email import encoders
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

If you need any other reference please feel free to ask.

Thank you.

Again having massive internet connection issues, therefore this post via e-mail in the hope it will get transmitted asynchronously.
But I was able to upload Nuitka plugin changes for this issue:
The jorj branch has an updated DataFileCollector.py plugin, which is sufficient to successfully to execute your imports.
Good look with it!

I have used the jorj branch but getting the following error after generating the exe.

websense-url-checker.exe

Can you please confirm that your DataFileCollectorPlugin.py located in nuitka/plugins/standard looks like so:

[himadriganguly]

I have downloaded the source code and used

python setup.py install

but after installing when running

nuitka --version

it is showing

0.6.5
Python: 3.7.4 (tags/v3.7.4:e09359112e, Jul  8 2019, 20:34:20) [MSC v.1916 64 bit (AMD64)]
Executable: C:\Users\[USERNAME]\AppData\Local\Programs\Python\Python37\python.exe
OS: Windows
Arch: x86_64

Please help me to figure out what I doing wrong.
