Python 在 Mac 上通过 chromedriver 使用 selenium

Use selenium with chromedriver on Mac

提问by wyx

I want to use selenium with chromedriver on Mac,but I have some troubles on it.

我想在 Mac 上将 selenium 与 chromedriver 一起使用，但是我遇到了一些麻烦。

1. I download the chromedriver from ChromeDriver - WebDriver for Chrome
2. But I don't want to put it to PATH.So I do this.

1. 我从ChromeDriver - WebDriver for Chrome下载了 chromedriver
2. 但我不想把它放到 PATH.So 我这样做。

import os

from selenium import webdriver

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))
DRIVER_BIN = os.path.join(PROJECT_ROOT, "bin/chromedriver_for_mac")
print DRIVER_BIN
browser = webdriver.Chrome(DRIVER_BIN)
browser.get('http://www.baidu.com/')

But I can't get the result I want.

但我无法得到我想要的结果。

Traceback (most recent call last):
  File "/Users/wyx/project/python-scraping/se/test.py", line 15, in <module>
    browser = webdriver.Chrome(DRIVER_BIN)
  File "/Users/wyx/project/python-scraping/.env/lib/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 62, in __init__
    self.service.start()
  File "/Users/wyx/project/python-scraping/.env/lib/python2.7/site-packages/selenium/webdriver/common/service.py", line 71, in start
    os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'chromedriver_for_mac' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Exception AttributeError: "'Service' object has no attribute 'process'" in <bound method Service.__del__ of <selenium.webdriver.chrome.service.Service object at 0x107f96150>> ignored

1. Then I run brew cask install chromedriver.And I only run this without the driver path.

   browser = webdriver.Chrome()
   browser.get('http://www.baidu.com/')
   

3. 然后我运行brew cask install chromedriver。我只在没有驱动程序路径的情况下运行它。

   browser = webdriver.Chrome()
   browser.get('http://www.baidu.com/')
   

But it can't work either.

但它也不能工作。

Traceback (most recent call last):
  File "/Users/wyx/project/python-scraping/se/test.py", line 16, in <module>
    browser = webdriver.Chrome()
  File "/Users/wyx/project/python-scraping/.env/lib/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 62, in __init__
    self.service.start()
  File "/Users/wyx/project/python-scraping/.env/lib/python2.7/site-packages/selenium/webdriver/common/service.py", line 71, in start
    os.path.basename(self.path), self.start_error_message)

Exception AttributeError: "'Service' object has no attribute 'process'" in <bound method Service.__del__ of <selenium.webdriver.chrome.service.Service object at 0x105c08150>> ignored

Process finished with exit code 1

Finally I try to put it to /usr/bin

最后我试着把它放到 /usr/bin

?  Downloads sudo cp chromedriver /usr/bin
Password:
cp: /usr/bin/chromedriver: Operation not permitted

and I try to use export PATH=$PATH:/Users/wyx/project/python-scraping/se/bin/chromedriver_for_macin .zshrc . But

我尝试export PATH=$PATH:/Users/wyx/project/python-scraping/se/bin/chromedriver_for_mac在 .zshrc 中使用。但

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH.

selenium.common.exceptions.WebDriverException: 消息：'chromedriver' 可执行文件需要在 PATH 中。

So how to solve it，I want to use it with the driver path not in the PATH so I can deploy my project easily.

那么如何解决呢，我想使用它的驱动程序路径不在PATH中，这样我就可以轻松部署我的项目。

Solution:

解决方案：

1. brew cask install chromedriver
2. which chromedriverget the driver path
3. And then use it like this webdriver.Chrome("/usr/local/bin/chromedriver")

1. brew cask install chromedriver
2. which chromedriver获取驱动程序路径
3. 然后像这样使用它 webdriver.Chrome("/usr/local/bin/chromedriver")

But I don't know why so complex to use selenium.

但我不知道为什么使用硒这么复杂。

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH.

selenium.common.exceptions.WebDriverException: 消息：'chromedriver' 可执行文件需要在 PATH 中。

To launch chrome browser using ChromeDriveryou need to pass executable chromedriverlocation with executable itself into executable_path.

要使用 Chrome 浏览器启动，ChromeDriver您需要将可执行文件本身的可执行 chromedriver位置传递到executable_path.

You should try as below :-

你应该尝试如下： -

from selenium import webdriver

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))
DRIVER_BIN = os.path.join(PROJECT_ROOT, "bin/chromedriver_for_mac")

browser = webdriver.Chrome(executable_path = DRIVER_BIN)
browser.get('http://www.baidu.com/')

Or set PATHvariable using command with executableas :-

或使用可执行文件的命令设置PATH变量为：-

export PATH=$PATH:/Users/wyx/project/python-scraping/se/bin/chromedriver_for_mac

Then try to Initialize ChromeDriveras :-

然后尝试初始化ChromeDriver为：-

from selenium import webdriver

browser = webdriver.Chrome()
browser.get('http://www.baidu.com/')

For sake of simplicity:

为简单起见：

Download the chrome webdriver from this link. Copy the 'chromedriver' in the folder of python script.

从此链接下载 chrome webdriver 。复制python脚本文件夹中的'chromedriver'。

from selenium import webdriver
import os

url = 'http://www.webscrapingfordatascience.com/complexjavascript/'

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))
DRIVER_BIN = os.path.join(PROJECT_ROOT, "chromedriver")

driver = webdriver.Chrome(executable_path = DRIVER_BIN)

driver.get(url)

input('Press ENTER to close the automated browser')

driver.quit()

For me worked like this without complicating things

对我来说，像这样工作而不会使事情复杂化

1. Download chromedriverfrom official link(notice version of Chrome browser)
2. Unpack *.zipfile and file chromedrivercopy to location usr/local/bin/
3. Remove any path you put in file and just go with driver = webdriver.Chrome()
4. If probem still exist try to reopen PyCharm since sometimes need to be reopened in case to work

1. 从官方链接下载chromedriver（Chrome浏览器注意版本）
2. 解压*.zip文件并将文件chromedriver复制到位置usr/local/bin/
3. 删除您放在文件中的任何路径，然后使用driver = webdriver.Chrome()
4. 如果probem仍然存在，请尝试重新打开PyCharm，因为有时需要重新打开才能工作
