【问题讨论】：

我们需要查看您的源代码。您能否尝试在 Chrome 开发工具中粘贴您的 CSS 选择器并查看该元素是否突出显示。我猜要么元素未在 10 秒内加载，要么 CSS 选择器不正确。是否也可以提供HTML？所以我们可以看看它，看看我们是否可以缩短选择器

【解决方案1】：

模块“selenium.webdriver.support.expected_conditions”没有“presence_of_elements_located”成员；也许'presence_of_element_located'？

uid = WebDriverWait(self.driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, '#react-root > section > main > div > article > div > div:nth-child(1) > div > form > div:nth-child(2) > div > label > input')))
        uid.click()
        uid.send_keys(self.username)
