selenium.common.exceptions.WebDriverException：消息：“库”可执行文件可能具有错误的 ChromeDriver 权限
selenium.common.exceptions.WebDriverException: Message: 'library' executable may have wrong permissions for ChromeDriver
问：
我想使用 chrome webdriver 连接到“https://www.google.com”。 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，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

C:\Users\faisal\library不是通往 Chromederiver 的正确路径。提供 chromedriver 文件的实际路径。

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
在您的代码块中，您提到了：
driver = webdriver.Chrome("C:\\Users\\faisal\\library")
该错误清楚地表明您的程序正在考虑将库作为 ChromeDriver 二进制文件。因此错误。
但根据 selenium.webdriver.chrome.webdriver 的文档，对 的调用如下：WebDriver()
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，您需要将 Key 和 Value 一起更改为单个 qoute 中的绝对路径以及原始开关，如下所示：executable_path''(r)
driver = webdriver.Chrome(executable_path=r'C:\Users\faisal\library\chromedriver.exe')
更新
根据 @Mangohero1 的反驳问题，粗略是可选的，但如果您仅提供绝对路径，则根据下面提供的源代码，绝对路径被视为键的值。executable_pathexecutable_path
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

实际上，如果我没记错的话，显式设置密钥是可选的。但是，是的，它必须是绝对的道路。executable_path

driver=webdriver.Chrome("C:\\Users\\SQA Anas\\Downloads\\chromedriver.exe")
请输入完整的 chrome 驱动程序路径，如下所示： “C：\Users\SQA Anas\Downloads\chromedriver.exe”
它对我有用:)

在Linux的情况下，提供权限将解决问题。
用
sudo chmod +x chromedriver

我不得不使用以下内容来运行：Windows 1064 bit32 bit chromedriver
driver = webdriver.Chrome(executable_path=r'C:\\Users\\My Name\\Downloads\\chromedriver_win32\\chromedriver.exe')

executable_path最后应该添加 chromedriver：
executable_path='/home/selenium/Linkedin-Automation/chromedriver'
