在Mac上使用含有chromedriver的硒

Question

我想在Mac上使用chlenium和chromedriver，但我有一些麻烦。

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



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/')

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. 然后我运行brew cask install chromedriver。我只运行它 没有司机路径。

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

但它也无法发挥作用。

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)
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' 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 0x105c08150>> ignored

Process finished with exit code 1

最后我尝试将它放到/ usr / bin

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

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

  

selenium.common.exceptions.WebDriverException：消息：＆＃39; chromedriver＆＃39;可执行文件需要在PATH中。

所以如何解决它，我想将它与不在PATH中的驱动程序路径一起使用，这样我就可以轻松部署我的项目了。

解决方案：

1. brew cask install chromedriver
2. which chromedriver获取驱动程序路径
3. 然后像webdriver.Chrome("/usr/local/bin/chromedriver")
一样使用它

  

但我不知道为什么使用硒这么复杂。

Answer 1

  

selenium.common.exceptions.WebDriverException：消息：＆＃39; chromedriver＆＃39;可执行文件需要在PATH中。

To launch chrome browser using ChromeDriver您需要将executable chromedriver位置与可执行文件本身一起传递到executable_path。

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/')

或将PATH变量using command with executable设置为： -

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

然后尝试将ChromeDriver初始化为： -

from selenium import webdriver

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

Answer 2

对我来说，这样工作不会使事情复杂化

1. 从官方 link （Chrome浏览器的公告版本）下载 chromedriver
2. 解压缩 *。zip 文件和文件 chromedriver 并复制到位置 usr / local / bin /
3. 删除您放入文件中的所有路径，然后使用 driver = webdriver.Chrome（）
4. 如果探针仍然存在，请尝试重新打开PyCharm，因为有时需要重新打开PyCharm

Answer 3

为简单起见：

从此link下载chrome webdriver。 复制＆＃39; chromedriver＆＃39;在python脚本的文件夹中。

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()

Answer 4

对我来说，通过自制软件安装chromedriver就像在MacOS 11上一样具有魅力。

brew install chromedriver && brew update
