如何通过Chromedriver和Selenium启动Chrome浏览器

I am getting error issues all of a sudden with selenium and the chromedriver. I haven't changed a single thing yet I am met with these error messages. The script literally worked hours ago and now without any tweaks its not working.

我一直在用硒和chromedriver得到错误问题。我没有改变任何一件事,但我遇到了这些错误消息。该脚本几个小时前完成了工作,现在没有任何调整它无法正常工作。

 traceback (most recent call last):
  File "email.py", line 3, in <module>
    from selenium import webdriver
  File "C:\ProgramData\Anaconda3\lib\site-packages\selenium\webdriver\__init__.py", line 18, in <module>
    from .firefox.webdriver import WebDriver as Firefox  # noqa
  File "C:\ProgramData\Anaconda3\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 20, in <module>
    import http.client as http_client
  File "C:\ProgramData\Anaconda3\lib\http\client.py", line 71, in <module>
    import email.parser
  File "C:\Users\Doe Labs\Desktop\Austin\Scripts\email.py", line 12, in <module>
    options = webdriver.ChromeOptions()

Here is my corresponding code:

这是我的相应代码:

import pyautogui
import time
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.support.ui import WebDriverWait

caps = DesiredCapabilities().CHROME
#caps["pageLoadStrategy"] = "eager"

options = webdriver.ChromeOptions() 
options.add_argument(r'load-extension=C:\Users\Doe Labs\Desktop\Austin\sales_prospecting\facebookpixelhelper')
#options.add_argument('start-fullscreen')
options.add_argument('disable-infobars')
driver=webdriver.Chrome(desired_capabilities = caps, executable_path=r'C:\Users\Doe Labs\Desktop\Austin\sales_prospecting\chromedriver', chrome_options=options)

driver.get('http://www.doelabs.com/')
driver.maximize_window()

Even more strange is that when open new terminal, load python, and type from selenium import webdriver, i dont get any errors. But, when I navigate to the folder where the script lives, and load python and type from selenium import webdriver, i get the error message that shows up above. I hope this can give some insight into my current predicament.

更奇怪的是,当打开新终端,加载python,并从selenium import webdriver输入时,我不会得到任何错误。但是,当我导航到脚本所在的文件夹,并从selenium import webdriver加载python和type时,我收到上面显示的错误消息。我希望这可以让我对目前的困境有所了解。

A few words about the solution :

关于解决方案的几句话:

email is a reserved word / keyword in Python Language, avoid using the word email within user defined filename/methods/classes.

email是Python语言中的保留字/关键字,避免在用户定义的文件名/方法/类中使用单词email。

pageLoadStrategy as eager is yet to be implemented in ChromeDriver, use either none or normal instead as per your requirement.

pageLoadStrategy as eager尚未在ChromeDriver中实现,请根据您的要求使用none或normal。

To maximize the Chrome Browser Window instead of maximize_window() use the argument start-maximized through ChromeOptions()

要最大化Chrome浏览器窗口而不是maximize_window(),请使用通过ChromeOptions()启动最大化的参数

To load an extension use ChromeOptions as follows :

要加载扩展程序,请使用ChromeOptions,如下所示:
```
options.addExtensions(new File("/path/to/extension.crx"));
```

Here are the four methods to initialize Chrome Browser through ChromeDriver :

以下是通过ChromeDriver初始化Chrome浏览器的四种方法:

Vanila Method :

Vanila方法:

from selenium import webdriver

driver = webdriver.Firefox(r'C:\path\to\chromedriver.exe')
driver.get('http://www.doelabs.com/')
print("Page Title is : %s" %driver.title)
driver.quit()

Arguments as ChromeOptions :

作为ChromeOptions的参数:

from selenium import webdriver

options = webdriver.ChromeOptions() 
options.addExtensions(new File("C:\Users\Doe Labs\Desktop\Austin\sales_prospecting\facebookpixelhelper.crx"));
options.add_argument('start-maximized')
options.add_argument('disable-infobars')
driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://www.doelabs.com/')
print("Page Title is : %s" %driver.title)
driver.quit()

Capabilities as DesiredCapabilities :

能力为DesiredCapabilities:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities().CHROME.copy()
caps["pageLoadStrategy"] = "normal"
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', desired_capabilities=caps)
driver.get('http://www.doelabs.com/')
print("Page Title is : %s" %driver.title)
driver.quit()

Arguments as ChromeOptions and Capabilities as DesiredCapabilities :

作为DesiredCapabilities的ChromeOptions和Capabilities的参数:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities().CHROME.copy()
caps["pageLoadStrategy"] = "normal"

options = webdriver.ChromeOptions() 
options.addExtensions(new File("C:\Users\Doe Labs\Desktop\Austin\sales_prospecting\facebookpixelhelper.crx"));
options.add_argument('start-maximized')
options.add_argument('disable-infobars')
driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\path\to\chromedriver.exe', desired_capabilities=caps)
driver.get('http://www.doelabs.com/')
print("Page Title is : %s" %driver.title)
driver.quit()

You might want to change

你可能想要改变

executable_path=r'C:\Users\Doe Labs\Desktop\Austin\sales_prospecting\chromedriver',

executable_path=r'C:\Users\Doe Labs\Desktop\Austin\sales_prospecting\chromedriver.exe',

You seem to have missed .exe, the extension of the executable file.

您似乎错过了.exe,可执行文件的扩展名。
