python-3.x - selenium.common.exceptions.NoSuchElementException: Message: no such element error using ChromeDriver and Chrome through Selenium and Python

Question

我正在创建一个机器人来在 instagram 上注册帐户，当我在本地（Mac OS）运行我的 selenium 脚本时，它运行良好，而当我在 Azure Cloud 上的 Ubuntu 18.4 上运行时，它无法本地化选择器，所以实际上我已经尝试了从改变xpath 到 ID 等等。

这是 ssh 控制台的输出

该程序应该是创建用户并将其存储在其他程序用于登录 Instagram 的 .txt 文件中。

在 mac 上，控制台运行时没有错误。

Answer 1

此错误消息...

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element:{"method":"id","selector":"igCoreRadioButtonageRadioabove_18"}
  (Session info: chrome=73.0.3683.86)
  (Driver info: chromedriver=2.35.528139 (47ead77cb35ad2a9a83248b292151462a66cd881),platform=Linux 4.18.0-1014-azure x86_64)

...意味着ChromeDriver无法找到所需的元素并且引发了NoSuchElementException。

使用 Chrome 时，您可以在Selenium “selenium.common.exceptions.NoSuchElementException”中找到关于NoSuchElementException的详细讨论

但是，您的主要问题是您使用的二进制文件版本之间的不兼容，如下所示：

• 您正在使用chromedriver=2.35
• chromedriver=2.35的发行说明清楚地提到了以下内容：

支持Chrome v62-64

• 您正在使用chrome=73.0
• ChromeDriver v2.46的发行说明清楚地提到了以下内容：

支持Chrome v71-73

所以ChromeDriver v2.35和Chrome Browser v73.0之间存在明显的不匹配

---

解决方案

• 将ChromeDriver升级到当前的ChromeDriver v2.46级别。
• 将Chrome版本保持在Chrome v71-73级别之间。（根据 ChromeDriver v2.46 发行说明）
