🛠️ Troubleshooting

Common Issues and Solutions

"File not found" Error

# Check file path and permissions
ls -la path/to/subscriptions.mhtml

# Use absolute path
python bin/extract.py /full/path/to/subscriptions.mhtml

"No channels found" Error

Verify file format: Ensure the file is a complete MHTML/Web Archive
Check subscription visibility: Make sure subscriptions are public on YouTube
Re-export file: Try saving the YouTube page again with a different browser

"Encoding issues" with special characters

# Try different encoding
python bin/extract.py subscriptions.mhtml --encoding utf-8-sig
python bin/extract.py subscriptions.mhtml --encoding latin1

Low data coverage (missing images/descriptions)

# Use comprehensive mode (default)
python bin/extract.py subscriptions.mhtml --quality comprehensive --verbose

Memory issues with large files

# Use fast mode for large subscription lists
python bin/extract.py large_file.mhtml --quality fast

Debug Mode

For detailed troubleshooting:

python bin/extract.py subscriptions.mhtml --verbose

Platform-Specific Issues

Windows:

Use Command Prompt or PowerShell as Administrator if needed
Ensure Python is in your PATH: python --version
Try: py bin/extract.py instead of python bin/extract.py

macOS:

May need to use python3 instead of python
Install Xcode Command Line Tools if needed: xcode-select --install
For permission issues: chmod +x scripts/install.sh

Linux:

Install Python 3 development headers: sudo apt install python3-dev
For permission issues: chmod +x scripts/install.sh
Try: python3 bin/extract.py
