在Mac上将硒与chromedriver一起使用

Question

我想在Mac上将硒与chromedriver一起使用，但遇到了一些麻烦。

1. 我从下载chromedriver ChromeDriver-WebDriver for Chrome
2. 但我不想将其放入PATH。

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/')

但是我无法获得想要的结果。

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

3. 然后我运行brew cask install chromedriver。并且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/')
   

但这也不行。

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，我尝试将其放入/ usr / bin

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

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

selenium.common.exceptions.WebDriverException：消息：“ chromedriver”可执行文件必须位于PATH中。

那么如何解决呢？

解：

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

但是我不知道为什么使用硒如此复杂。

Answer 1

为简单起见：

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()

Answer 2

selenium.common.exceptions.WebDriverException：消息：“ chromedriver”可执行文件必须位于PATH中。

要使用启动Chrome浏览器，ChromeDriver您需要将chromedriver可执行文件及其可执行文件本身传递到executable_path。

您应该尝试以下方法：

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/')

或使用命令将PATH变量设置为可执行文件：

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

然后尝试初始化ChromeDriver为：-

from selenium import webdriver

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

Answer 3

对我来说，像这样工作而不会使事情复杂化

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
