我有一个Python selenium程序工作大约一周前。现在selenium导入失败：
from selenium import webdriver
IDLE输出：

当我尝试用pip重新安装软件包时，我被告知满足要求。
chromedriver.exe位于c：\ Windows \ system32中。
任何想法都非常感激。
您的webdriver安装文件已损坏或丢失。重新安装/升级webdriver eggs。
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\Mike\\AppData\\Local\\Programs\\Python\\Python36-32\\lib\\site-packages\\selenium\\webdriver\\remote\\getAttribute.js'
试试这个：
pip install selenium --upgrade
该错误确实给了我们一些关于错误发生的提示，如下所示：
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\Mike\\AppData\\Local\\Programs\\Python\\Python36-32\\lib\\site-packages\\selenium\\webdriver\\remote\\getAttribute.js'
这实际上意味着在它的预期位置找不到getAttribute.js。
getAttribute.js文件内部使用错误和其他关键JavaScript函数，如下所示：
典型的getAttribute.js文件如下所示：

如果没有正确下载getAttribute.js文件，Selenium和webdriver模块可能无法正常工作。如果Selenium客户端在传输或存储期间遇到任何错误，则可能会出现此问题。
Selenium团队目前正在研究SeleniumHQ/selenium/5378问题，以生成Downloaded Selenium Client的二进制校验和，这将帮助您避免遇到可能在传输或存储期间引入的错误。
然后解决方案将是：
