Selenium chromdriver一直给我错误

Question

我已经能够利用硒铬一段时间。我尝试使用

捕获错误

try:
#check if it already exist before doing anything
webdriver.driver
except:
chromeBrowser=ChromeDriverManager().install() 
....... some other code here

上面的代码工作得很好，它捕获错误并加载浏览器没有任何问题。突然，它开始给我这个错误，没有超出这个范围。它甚至根本没有进入互联网。

请我现在该怎么办，我不知道该怎么办。我甚至完全删除了try异常语句，但这并没有帮助。

这一切都是在我升级selenium后不久开始的。之后，我试图逆转升级，但可以得到初始版本，但我仍然使用另一个版本，但它仍然给我相同的错误。

通常在selenium升级之前，它会为我下载驱动程序并运行浏览器。但是现在连我的网络都连接不上了。

在你的错误堆栈中有这个错误:

Could not get version for Chrome with this command: reg query "HKEY_CURRENT_USERSoftwareGoogleChromeBLBe
acon" /v version

在这个错误后面会出现一些重复的问题。你试过这些帖子里的建议吗?它们能解决你的问题吗?

似乎python无法找到chrome，这就是为什么你得到错误。
