我自己做了一个Twitter投诉机器人，如果网络中断，它会在我的ISP上发推文。代码工作得很完美，直到它必须找到Twitter文本框来输入推文。主要错误是：

StaleElementReferenceException: Message: stale element reference: element is not attached to the page document

我试过：

• 添加时间延迟
• 使用Firefox驱动程序而不是Google
• 在tweet_at_provider（）查找文本框之前添加页面刷新
• 点击"Tweet"按钮，弹出文本框，然后尝试输入
• 使用find. element_by_id，但twitter在每次页面加载时都会更改id

当我注解掉要测试的第一个函数调用时，它会查找并键入6/10次，但当两个函数都被调用时，tweet_at_provider（）总是无法获取文本框，我得到StaleElement错误。
