在Chrome中运行Selenium WebDriver python绑定

问题:在Chrome中运行Selenium WebDriver python绑定

使用Selenium时遇到问题。对于我的项目,我必须使用Chrome。但是,用Selenium启动该浏览器后,我无法连接到该浏览器。

由于某些原因,Selenium本身无法找到Chrome。当我尝试启动Chrome而没有添加路径时,会发生以下情况:

Traceback (most recent call last):
  File "./obp_pb_get_csv.py", line 73, in <module>
    browser = webdriver.Chrome() # Get local session of chrome
  File "/usr/lib64/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 46, in __init__
    self.service.start()
  File "/usr/lib64/python2.7/site-packages/selenium/webdriver/chrome/service.py", line 58, in start
    and read up at http://code.google.com/p/selenium/wiki/ChromeDriver")
selenium.common.exceptions.WebDriverException: Message: 'ChromeDriver executable needs to be available in the path.                 Please download from http://code.google.com/p/selenium/downloads/list                and read up at http://code.google.com/p/selenium/wiki/ChromeDriver'

为了解决此问题,我随后在启动Chrome的代码中包含了Chromium路径。但是,解释器无法找到要连接的套接字:

Traceback (most recent call last):
  File "./obp_pb_get_csv.py", line 73, in <module>
    browser = webdriver.Chrome('/usr/bin/chromium') # Get local session of chrome
  File "/usr/lib64/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 46, in __init__
    self.service.start()
  File "/usr/lib64/python2.7/site-packages/selenium/webdriver/chrome/service.py", line 64, in start
    raise WebDriverException("Can not connect to the ChromeDriver")
selenium.common.exceptions.WebDriverException: Message: 'Can not connect to the ChromeDriver'

我还尝试通过以下方式启动chrome解决问题:

铬--remote-shell-port = 9222

但是,这也不起作用。

PS。以下是有关我的系统的一些信息:

www-client:铬15.0.874.121  
dev-lang:python 2.7.2-r3 Selenium 2.11.1  
操作系统:GNU / Linux Gentoo Kernel 3.1.0-gentoo-r1

I ran into a problem while working with Selenium. For my project, I have to use Chrome. However, I can’t connect to that browser after launching it with Selenium.

For some reason, Selenium can’t find Chrome by itself. This is what happens when I try to launch Chrome without including a path:

Traceback (most recent call last):
  File "./obp_pb_get_csv.py", line 73, in <module>
    browser = webdriver.Chrome() # Get local session of chrome
  File "/usr/lib64/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 46, in __init__
    self.service.start()
  File "/usr/lib64/python2.7/site-packages/selenium/webdriver/chrome/service.py", line 58, in start
    and read up at http://code.google.com/p/selenium/wiki/ChromeDriver")
selenium.common.exceptions.WebDriverException: Message: 'ChromeDriver executable needs to be available in the path.                 Please download from http://code.google.com/p/selenium/downloads/list                and read up at http://code.google.com/p/selenium/wiki/ChromeDriver'

To solve this problem, I then included the Chromium path in the code that launches Chrome. However, the interpreter fails to find a socket to connect to:

Traceback (most recent call last):
  File "./obp_pb_get_csv.py", line 73, in <module>
    browser = webdriver.Chrome('/usr/bin/chromium') # Get local session of chrome
  File "/usr/lib64/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 46, in __init__
    self.service.start()
  File "/usr/lib64/python2.7/site-packages/selenium/webdriver/chrome/service.py", line 64, in start
    raise WebDriverException("Can not connect to the ChromeDriver")
selenium.common.exceptions.WebDriverException: Message: 'Can not connect to the ChromeDriver'

I also tried solving the problem by launching chrome with:

chromium --remote-shell-port=9222

However, this did not work either.

PS. Here’s some information about my system:

www-client: chromium 15.0.874.121  
dev-lang:   python 2.7.2-r3 Selenium 2.11.1  
OS:         GNU/Linux Gentoo Kernel 3.1.0-gentoo-r1

您需要确保独立的ChromeDriver二进制文件(与Chrome浏览器二进制文件不同)位于您的路径中或在webdriver.chrome.driver环境变量中可用。

有关如何进行整理的完整信息,请参见http://code.google.com/p/selenium/wiki/ChromeDriver

编辑:

是的,似乎是从路径环境变量读取chromedriver二进制文件的Python绑定中的错误。似乎chromedriver不在您的路径中,您必须将其作为参数传递给构造函数。

import os
from selenium import webdriver

chromedriver = "/Users/adam/Downloads/chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
driver = webdriver.Chrome(chromedriver)
driver.get("http://stackoverflow.com")
driver.quit()

You need to make sure the standalone ChromeDriver binary (which is different than the Chrome browser binary) is either in your path or available in the webdriver.chrome.driver environment variable.

see http://code.google.com/p/selenium/wiki/ChromeDriver for full information on how wire things up.

Edit:

Right, seems to be a bug in the Python bindings wrt reading the chromedriver binary from the path or the environment variable. Seems if chromedriver is not in your path you have to pass it in as an argument to the constructor.

import os
from selenium import webdriver

chromedriver = "/Users/adam/Downloads/chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
driver = webdriver.Chrome(chromedriver)
driver.get("http://stackoverflow.com")
driver.quit()

对于Linux

  1. 检查您是否安装了最新版本的Chrome浏览器-> chromium-browser -version
  2. 如果没有,请安装最新版本的chrome sudo apt-get install chromium-browser
  3. 此处获取适当版本的chrome驱动程序
  4. 解压缩chromedriver.zip
  5. 将文件移到/usr/bin目录sudo mv chromedriver /usr/bin
  6. 转到/usr/bin目录cd /usr/bin
  7. 现在,您需要运行类似sudo chmod a+x chromedriver将其标记为可执行文件的操作。
  8. 最后,您可以执行代码。

    from selenium import webdriver
    
    driver = webdriver.Chrome()
    driver.get("http://www.google.com")
    print driver.page_source.encode('utf-8')
    driver.quit()
    display.stop()

For Linux

  1. Check you have installed latest version of chrome brwoser-> chromium-browser -version
  2. If not, install latest version of chrome sudo apt-get install chromium-browser
  3. get appropriate version of chrome driver from here
  4. Unzip the chromedriver.zip
  5. Move the file to /usr/bin directory sudo mv chromedriver /usr/bin
  6. Goto /usr/bin directory cd /usr/bin
  7. Now, you would need to run something like sudo chmod a+x chromedriver to mark it executable.
  8. finally you can execute the code.

    from selenium import webdriver
    
    driver = webdriver.Chrome()
    driver.get("http://www.google.com")
    print driver.page_source.encode('utf-8')
    driver.quit()
    display.stop()

仅Mac OSX

进行以下操作的更简单方法(假设您已经安装了自制软件,如果没有,应该先这样做,然后让自制软件使您的生活变得更好),只需运行以下命令:

brew install chromedriver

那应该将chromedriver放在您的路径中,并且您已经准备就绪。

Mac OSX only

An easier way to get going (assuming you already have homebrew installed, which you should, if not, go do that first and let homebrew make your life better) is to just run the following command:

brew install chromedriver

That should put the chromedriver in your path and you should be all set.

对于窗户

从此直接链接 下载ChromeDriver 从此页面获取最新版本

将该chromedriver.exe文件粘贴到C:\Python27\Scripts文件夹中。

现在应该可以使用:

from selenium import webdriver
driver = webdriver.Chrome()

For windows

Download ChromeDriver from this direct link OR get the latest version from this page.

Paste the chromedriver.exe file in your C:\Python27\Scripts folder.

This should work now:

from selenium import webdriver
driver = webdriver.Chrome()

回答 4

对于窗户,请chromedriver.exe放在下面<Install Dir>/Python27/Scripts/

For windows, please have the chromedriver.exe placed under <Install Dir>/Python27/Scripts/

有两种方法可以在Google Chrome浏览器中运行Selenium python测试。我正在考虑Windows(以Windows 10为例):

先决条件:从以下网址下载最新的Chrome驱动程序:https : //sites.google.com/a/chromium.org/chromedriver/downloads

方法1:

i)将下载的zip文件解压缩到您选择的目录/位置中
ii)如下所示在代码中设置可执行路径:

self.driver = webdriver.Chrome(executable_path='D:\Selenium_RiponAlWasim\Drivers\chromedriver_win32\chromedriver.exe')

方式2:

i)只需将chromedriver.exe粘贴在/ Python / Scripts /下(在我的情况下,文件夹为:C:\ Python36 \ Scripts)
ii)现在编写如下的简单代码:

self.driver = webdriver.Chrome()

There are 2 ways to run Selenium python tests in Google Chrome. I’m considering Windows (Windows 10 in my case):

Prerequisite: Download the latest Chrome Driver from: https://sites.google.com/a/chromium.org/chromedriver/downloads

Way 1:

i) Extract the downloaded zip file in a directory/location of your choice
ii) Set the executable path in your code as below:

self.driver = webdriver.Chrome(executable_path='D:\Selenium_RiponAlWasim\Drivers\chromedriver_win32\chromedriver.exe')

Way 2:

i) Simply paste the chromedriver.exe under /Python/Scripts/ (In my case the folder was: C:\Python36\Scripts)
ii) Now write the simple code as below:

self.driver = webdriver.Chrome()

对于Windows的IDE:

如果您的路径不起作用,则可以尝试将其添加chromedriver.exe到您的项目中,就像在此项目结构中一样。

然后,您应该chromedriver.exe在主文件中加载。至于我,我装了driver.exedriver.py

def get_chrome_driver():
return webdriver.Chrome("..\\content\\engine\\chromedriver.exe",
                            chrome_options='--no-startup-window')

..表示driver.py's上层目录

. 表示目录 driver.py位于

希望这会有所帮助。

For Windows’ IDE:

If your path doesn’t work, you can try to add the chromedriver.exe to your project, like in this project structure.

Then you should load the chromedriver.exe in your main file. As for me, I loaded the driver.exe in driver.py.

def get_chrome_driver():
return webdriver.Chrome("..\\content\\engine\\chromedriver.exe",
                            chrome_options='--no-startup-window')

.. means driver.py's upper directory

. means the directory where the driver.py is located

Hope this will be helpful.
