AttributeError:“Ghost”对象没有“click”属性

Question

我尝试使用python的ghost库在无头浏览器中单击一个元素，如下所示：

ghost = Ghost()
USERAGENT = "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0"

with ghost.start():
    session = Session(ghost, download_images=True, display=True, user_agent=USERAGENT)
    session.load_cookies("cookies.txt", keep_old=False)
    page, rs = session.open("{url-here}", timeout=120)
    session.wait_for_page_loaded(timeout=None)
    assert page.http_status == 200

    while session.exists("#selector"):
        page, rs = ghost.click("#selector")
        session.wait_for_page_loaded(timeout=None)

这将返回错误消息：

^{pr2}$

我也试过：

page, rs = ghost.evaluate("document.getElementByClassName('#selector').click();", expect_loading=True)

它给出了相同的错误消息。我用鬼魂做了什么错事？在
