Python Selenium-使用元素时出现过时元素引用异常。单击（）

错误输出：

selenium.common.exceptions.StaleElementReferenceException: Message: The element reference of <span class="a-size-medium a-color-base a-text-normal"> is stale; either 
the element is no longer attached to the DOM, it is not in the current frame context, or the document has been refreshed

由于您使用的是driver.back（），因此它刷新了页面，并且您捕获的元素不再附加到页面上。您需要重新分配这些元素

试试下面的代码

def experiment2():
    browser = webdriver.Firefox()
    browser.get("https://www.amazon.com/")
    searchelement = browser.find_element_by_css_selector("#twotabsearchtextbox")
    searchelement.send_keys('automate the boring stuff with python')
    searchelement.submit()
    time.sleep(5)
    elements = browser.find_elements_by_css_selector("span.a-color-base.a-text-normal")
    for element in range(len(elements)):
        elements = browser.find_elements_by_css_selector("span.a-color-base.a-text-normal")
        elements[element].click()
        try:
            element = browser.find_element_by_css_selector("span.a-size-medium:nth-child(2)")
            print(element.text)
        except:
            browser.back()
            time.sleep(2)
            continue
        browser.back()
        time.sleep(2)
