问题描述
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'm beginning the automate the boring stuff book and I'm trying to open a chrome web browser through python. I have already installed selenium and
我已尝试运行此文件:
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')
但正因为如此,我得到了这个错误:
But because of that I get this Error:
Traceback (most recent call last): File "C:\Program Files
(x86)\Python36-32\lib\site-packages\selenium\webdriver\common\service.py",
line 74, in start

在处理上述异常的过程中,又发生了一个异常:
During handling of the above exception, another exception occurred:

推荐答案
您需要指定chromedriver所在的路径.
将 chromedriver 放在您的系统路径或代码所在的位置.
Place chromedriver on your system path, or where your code is.
如果不使用系统路径,请链接您的 chromedriver.exe
(对于非 Windows 用户,它仅称为 chromedriver
):
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")
(将 executable_path
设置为您的 chromedriver 所在的位置.)
(Set executable_path
to the location where your chromedriver is located.)
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:
If you've placed chromedriver on your System Path, you can shortcut by just doing the following:
browser = webdriver.Chrome()
如果您在基于 Unix 的操作系统上运行,您可能需要在下载 chromedriver 后更新其权限以使其可执行:
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
仅此而已.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:可以不要为 Selenium 使用 chrome 驱动程序
