```bash
# Option 1: Start with uvicorn directly
uv run uvicorn main:api --port 5001

# Option 2: Standalone mode (no Electron dependency)
uv run python main.py

# Option 3: If uv run hangs, delete lock files and retry, or use venv directly:
.venv/bin/python main.py
# or
.venv/bin/uvicorn main:api --port 5001 --host 0.0.0.0

# If uv hangs, delete lock files first: rm -f uv_installing.lock uv_installed.lock
```

```bash

pybabel extract -F babel.cfg -o messages.pot . --ignore-pot-creation-date  # Extract multilingual strings from code to messages.pot file
pybabel init -i messages.pot -d lang -l zh_CN   # Generate Chinese language pack, can only be generated initially, subsequent execution will cause overwrite
pybabel compile -d lang -l zh_CN                # Compile language pack


pybabel update -i messages.pot -d lang
# -i messages.pot: Specify the input file as the generated .pot file
# -d translations: Specify the translation directory, which typically contains .po files for each language
# -l zh: Specify the language code
