编辑

当我尝试这段代码时它确实有效，但我不知道为什么它突然有效有人能解释一下这段代码吗?

It does work when I try this code, but I don't know why it suddenly worksCan someone explain this code?

driver=webdriver.Chrome(executable_path="C:/UsersDannyDownloadschromedriver_win32chromedriver.exe")

for i in range(1,10):
driver.get('https://google.com')

推荐答案

您看到的错误提示我们如下:

The error you are seeing gives us some hint as follows :

WebDriverException                        Traceback (most recent call last)
<ipython-input-36-6bcc3a6d3d05> in <module>()
----> 1 driver.get('https://google.com')

以下是一些观察和补救措施:

Here are some observations and remedies :

• 首先，我希望您回顾一下 ChromeDriver 二进制文件的确切绝对路径，我的猜测是:

• First of all, I would like you to look back at the exact absolute path of the ChromeDriver binary and my guess is instead of :

/Users/Users/Downloads/chromedriver_win32/chromedriver

应该是:

/Users/Downloads/chromedriver_win32/chromedriver

此外，传递 ChromeDriver 二进制文件位置的更好方法是同时传递参数 executable_path，因此该行将是:

Moreover, a better way to pass the location of the ChromeDriver binary would be to pass the argument executable_path along as well, so the line would be :

driver = webdriver.Chrome(executable_path=r'/Users/Users/Downloads/chromedriver_win32/chromedriver')

最后，每当您调用 get() 方法打开一个 URL 时，请尝试传递 完全限定域名 (FQDN) 如下:

Finally, whenever you invoke get() method to open an URL try to pass the Fully Qualified Domain Name (FQDN) as follows :

driver.get('https://www.google.co.in')
