Question

我想使用chrome webdriver连接到＆＃34; https://www.google.com＆＃34;。下面是代码。

from selenium import webdriver  
import time  

driver = webdriver.Chrome("C:\\Users\\faisal\\library")  
driver.set_page_load_timeout(10)  
driver.get("https://www.google.com")  
driver.find_element_by_name("q").send_keys(" automation by name ")  
driver.find_element_by_name("blink").click()  
time.sleep(5)  
driver.close()

运行测试时，会显示以下错误消息。这是一个权限问题

C:\Users\faisal\PycharmProjects\firstSeleniumTest2\venv\Scripts\python.exe C:/Users/faisal/PycharmProjects/firstSeleniumTest2/test.py
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Answer 1

C:\Users\faisal\library不是chromedriver的正确途径。给出chromedriver文件的实际路径。

Answer 2

错误说明了一切：

selenium.common.exceptions.WebDriverException: Message: 'library' executable may have wrong permissions. Please see https://sites.google.com/a/chromium.org/chromedriver/home

在你提到的代码块中：

driver = webdriver.Chrome("C:\\Users\\faisal\\library")

错误清楚地表明您的程序正在考虑库作为 ChromeDriver 二进制文件。因此错误。

但根据selenium.webdriver.chrome.webdriver的文档，对WebDriver()的调用如下：

class selenium.webdriver.chrome.webdriver.WebDriver(executable_path='chromedriver', port=0, options=None, service_args=None, desired_capabilities=None, service_log_path=None, chrome_options=None)

因此，您需要更改发送键 executable_path以及 Value 作为单个qoute ''中的绝对路径以及原始值(r)切换如下：

driver = webdriver.Chrome(executable_path=r'C:\Users\faisal\library\chromedriver.exe')

更新

根据来自@ Mangohero1的粗略executable_path的反问题是可选的，但是如果您根据绝对路径下面提供的源代码仅提供绝对路径 被视为键 executable_path的值。

class WebDriver(RemoteWebDriver):
    """
    Controls the ChromeDriver and allows you to drive the browser.

    You will need to download the ChromeDriver executable from
    http://chromedriver.storage.googleapis.com/index.html
    """

    def __init__(self, executable_path="chromedriver", port=0,
         options=None, service_args=None,
         desired_capabilities=None, service_log_path=None,
         chrome_options=None):
    """
    Creates a new instance of the chrome driver.

    Starts the service and then creates new instance of chrome driver.

    :Args:
     - executable_path - path to the executable. If the default is used it assumes the executable is in the $PATH

Answer 3

如果使用Linux，则提供许可将解决问题。

使用

sudo chmod +x chromedriver

Answer 4

我必须使用以下代码在Windows 10 64位32位chromedriver上运行：driver = webdriver.Chrome（executable_path = r'C：\ Users \ My Name \ Downloads \ chromedriver_win32 \ chromedriver.exe'）

Answer 5

executable_path 应该最后添加了 chromedriver：

executable_path='/home/selenium/Linkedin-Automation/chromedriver'

selenium.common.exceptions.WebDriverException：消息：＆＃39; library＆＃39;可执行文件可能具有错误的ChromeDriver权限
