Environment Information

• Operating System: Fedora 40
• Fansly Downloader Version: 2a6e63f
• Fansly Downloader Type: Python Version
• Specific creators name: n/a

User Research

I have done the following:

• Looked through old GitHub issues
• Read the config.ini options
• Searched the Web (like DuckDuckGo)

Additional context

This is a simple dependency issue, solved by installing the correct development package, per this Stackoverflow answer (archived). Dependency issues are easy enough to solve but the packages on various systems can be a touch obscure, making it difficult for newer Linux users to figure out, so I am reporting this issue and my fix for posterity. A documentation update (probably just linking to the SO in the README.MD) could address this dependency for future reference.

Aside: I also had to install gcc-g++ package since Fedora doesn't come standard with that, so the call to g++ was failing.

I wound up having to install python 3.10.7 and after doing that I was able to install plyvel then re ran the requirements.txt and everything worked for me

I also had to delete line 52 and 107 of the IDLE for fansly_downloader_main.py - it was advised - as found in the following thread - #84

[blue-popsicle]

Oops, deleted my previous comment before I realized you responded. I was able to get plyvel installed manually through Powershell by first downloading the plyvel_ci-1.5.1-cp312-cp312-win_amd64.whl file from the Plyvel page on PyPI.
Now I seemingly have everything necessary installed, but the fansly_downloader_ng.py file just closes instantly seemingly without doing anything. No idea what's going on.

[blue-popsicle]

Oh! Commenting out lines 52 and 107 fixed that. Thanks for the help!

[deadbeatdandylyon]

Yeah I spent a lot of time as well trying to figure it out, but I didn't know how to do the .whl file install and I even tried at one point installing each requirement 1 at a time and it kept getting hung up on plyvel-ci till i found somewhere to install version 3.10 python and then i installed plyvel and it worked so odd

This isn't actually a bug in this project; instead, it is an issue with plyvel requiring the LevelDB development headers and share library. Specifically called out (https://plyvel.readthedocs.io/en/latest/installation.html)

I'm still struggling to get this to work on macOS Sonoma. I've used Homebrew to install leveldb with brew install leveldb, but I'm still getting the error 'leveldb/db.h' file not found.

I've tried this, but same results: wbolster/plyvel#114 (comment)

What worked for me on Sequoia was:

brew install leveldb
export LIBRARY_PATH="$LIBRARY_PATH:$(brew --prefix)/lib"
export CPATH="$CPATH:$(brew --prefix)/include"
python3 -m pip install plyvel

Thank you, @Jakan-Kink ! That did the trick!!
