Environment : Windows 11 (Conda) with Python 3.11.8 praisonAI 0.0.17

After installation ( : pip install praisonai

I ran the Initialise : praisonai --init create a movie script about dog in moon

it return error code as below , I think it's UTF-8 issue :

The problem is solved by adding the encoding="utf-8" into the create_or_modify_pyi() function in .\gradio\component_meta.py.

Four modifications are needed:

1 x Change source_file.read_text() to source_file.read_text(encoding="utf-8") once. 3 x Change pyi_file.read_text() to pyi_file.read_text(encoding='utf-8') three times.

def create_or_modify_pyi(
    component_class: type, class_name: str, events: list[str | EventListener]
):
    source_file = Path(inspect.getfile(component_class))

    source_code = source_file.read_text(encoding="utf-8") # <---- add utf-8 here

    current_impl, lineno = extract_class_source_code(source_code, class_name)

    if not (current_impl and lineno):
        raise ValueError("Couldn't find class source code")

    new_interface = create_pyi(current_impl, events)

    pyi_file = source_file.with_suffix(".pyi")
    if not pyi_file.exists():
        last_empty_line_before_class = -1
        lines = source_code.splitlines()
        for i, line in enumerate(lines):
            if line in ["", " "]:
                last_empty_line_before_class = i
            if i >= lineno:
                break
        lines = (
            lines[:last_empty_line_before_class]
            + ["from gradio.events import Dependency"]
            + lines[last_empty_line_before_class:]
        )
        with no_raise_exception():
            pyi_file.write_text("\n".join(lines))
    current_interface, _ = extract_class_source_code(pyi_file.read_text(encoding='utf-8'), class_name) # <---- add utf-8 here
    if not current_interface:
        with no_raise_exception():
            with open(str(pyi_file), mode="a") as f:
                f.write(new_interface)
    else:
        contents = pyi_file.read_text(encoding='utf-8') # <---- add utf-8 here
        contents = contents.replace(current_interface, new_interface.strip())
        current_contents = pyi_file.read_text(encoding='utf-8') # <---- add utf-8 here
        if current_contents != contents:
            with no_raise_exception():
                pyi_file.write_text(contents)
