【完美解決】使用flask的run啓動debug來運行puppeteer,報錯【signal only works in main thread 】的解決方案

解決方案：puppeteer在初始化launch時，必須增加以下的參數【handleSIGINT=False, handleSIGTERM=False, handleSIGHUP=False】才能使得flask的run-debug模式啓動也能正常運行！

puppeteer官方文檔：https://miyakogi.github.io/pyppeteer/reference.html#launcher

 _browser = await launch(
            {
                "headless": _headless,
                "defaultViewport": _defaultViewport,
                "args": _args,
                "handleSIGINT": False,
                "handleSIGTERM": False,
                "handleSIGHUP": False
            })
