DOWNLOADER_MIDDLEWARES = {
    'gerapy_pyppeteer.downloadermiddlewares.py.PyppeteerMiddleware': 543,
}

Others optional settings:

# pyppeteer logging level
GERAPY_PYPPETEER_LOGGING_LEVEL = logging.WARNING

# pyppeteer timeout
GERAPY_PYPPETEER_DOWNLOAD_TIMEOUT = 30

# pyppeteer browser window
GERAPY_PYPPETEER_WINDOW_WIDTH = 1400
GERAPY_PYPPETEER_WINDOW_HEIGHT = 700

# pyppeteer settings
GERAPY_PYPPETEER_HEADLESS = True
GERAPY_PYPPETEER_DUMPIO = False
GERAPY_PYPPETEER_DEVTOOLS = False
GERAPY_PYPPETEER_EXECUTABLE_PATH = None
GERAPY_PYPPETEER_DISABLE_EXTENSIONS = True
GERAPY_PYPPETEER_HIDE_SCROLLBARS = True
GERAPY_PYPPETEER_MUTE_AUDIO = True
GERAPY_PYPPETEER_NO_SANDBOX = True
GERAPY_PYPPETEER_DISABLE_SETUID_SANDBOX = True
