我将Selenium IDE导出到Python WebDriver并运行它。我收到此错误：异常或登录ID有问题。 NoSuchElementException：消息：无法找到元素：{“method”：“链接文本”，“选择器”：“登录”}

        self.base_url = `"https://www.yahoo.com/`"
        self.verificationErrors = []
        self.accept_next_alert = True

    def test_vova(self):
        driver = self.driver

Answer 1

find_element_by_link_text()只会找到链接 - a元素，但在UK Yahoo Mail页面上，Sign in文字位于div内：

<div id="signin" class="helvetica-bold uppercase">Sign in</div>

使用＆＃34;通过XPath＆＃34;而不是定位器：

driver.find_element_by_xpath("//div[. = 'Sign in']").click()

或者＆＃34;按ID＆＃34;：

driver.find_element_by_id("signin").click()

NoSuchElementException：消息：无法找到元素：{“method”：“链接文本”，“选择器”：“登录”}
