我正在开始自动化无聊的东西，我正在尝试通过 python 打开一个 chrome 网络浏览器。我已经安装了硒和

I have tried to run this file:

我试图运行这个文件：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys

browser = webdriver.Chrome()
browser.get('https://automatetheboringstuff.com')

But because of that I get this Error:

但正因为如此，我得到了这个错误：

Traceback (most recent call last):   File "C:\Program Files

During handling of the above exception, another exception occurred:

在处理上述异常的过程中，又发生了一个异常：

You need to specify the path where your chromedriver is located.

您需要指定 chromedriver 所在的路径。

1. Download chromedriver for your desired platform from here.

2. Place chromedriver on your system path, or where your code is.

3. If not using a system path, link your chromedriver.exe(For non-Windows users, it's just called chromedriver):

   browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")
   

   (Set executable_pathto the location where your chromedriver is located.)

   If you've placed chromedriver on your System Path, you can shortcut by just doing the following:

   browser = webdriver.Chrome()

4. If you're running on a Unix-based operating system, you may need to update the permissions of chromedriver after downloading it in order to make it executable:

   chmod +x chromedriver

5. That's all. If you're still experiencing issues, more info can be found on this other StackOverflow article: Can't use chrome driver for Selenium

1. 从此处下载适用于您所需平台的 chromedriver。

2. 将 chromedriver 放在您的系统路径或代码所在的位置。

3. 如果不使用系统路径，请链接您的chromedriver.exe（对于非 Windows 用户，它只是称为chromedriver）：

   browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")
   

   （设置executable_path为您的 chromedriver 所在的位置。）

   如果您已将 chromedriver 放在系统路径上，则只需执行以下操作即可快捷方式：

   browser = webdriver.Chrome()

4. 如果您在基于 Unix 的操作系统上运行，您可能需要在下载后更新 chromedriver 的权限以使其可执行：

   chmod +x chromedriver

5. 就这样。如果您仍然遇到问题，可以在另一篇 StackOverflow 文章中找到更多信息：Can't use chrome driver for Selenium

Here's a simpler solution: install python-chromedrive package, import it in your script, and it's done.

这是一个更简单的解决方案：安装 python-chromedrive 包，将其导入到您的脚本中，就完成了。

Step by step:
1. pip install chromedriver-binary
2. import the package

一步一步：
1. pip install chromedriver-binary
2. 导入包

from selenium import webdriver
import chromedriver_binary  # Adds chromedriver binary to path

driver = webdriver.Chrome()
driver.get("http://www.python.org")
