使用 Selenium 时是否需要安装 Chrome 或仅安装 chromedriver? [英] Is Chrome installation needed or only chromedriver when using Selenium?

问题描述

我尝试过搜索，但没有找到明确的答案.在没有实际安装 Chrome 浏览器的 Windows Server 2016 上.我下载了正确的chromedriver.exe"并将其放在D:Appschromedriver.exe"中.我已将完整路径作为D:Appschromedriver.exe"添加到我的环境 PATH.

I've tried to search, but haven't found a definitive answer. On Windows Server 2016 WITHOUT Chrome Browser actually installed. I downloaded the correct "chromedriver.exe" and placed it in "D:Appschromedriver.exe". I have added to my environment PATH the full path as "D:Appschromedriver.exe".

当我尝试启动使用最新 Selenium 的 Windows 服务时，我收到以下错误:

When I attempt to start my Windows Service that utilizes the latest Selenium, I get the following error:

Exception occurred: Failed initializing web driver: Message: unknown error: cannot find Chrome binary
  (Driver info: chromedriver=2.40.565498 (ea082db3280dd6843ebfb08a625e3eb905c4f5ab),platform=Windows NT 10.0.14393 x86_64)

问题:除了 chromedriver 之外，我是否必须实际安装完整的浏览器，或者这只是在我的 Python 代码中找不到 chromedriver.exe(包含在下面以供全面披露):

Question: Do I have to actually install the full-blown browser in addition to the chromedriver, or is this simply just not finding the chromedriver.exe in my Python code (included below for full disclosure):

def __init__(self, username, password, environment='cert'):
    self.username = username
    self.password = password
    self.environment = environment

    # Instantiate a chrome options object so you can set the size and headless preference
    self.chrome_options = Options()

    # Toggle Headless or not
    if HEADLESS_TOGGLE == 1:
        self.chrome_options.add_argument("--headless")

    self.chrome_options.add_argument("--disable-gpu")  # Disables "Lost UI Shared Context GPU Error on Windows"
    self.chrome_options.add_argument('--disable-extensions')  # Disables Extensions
    self.chrome_options.add_argument("--disable-software-rasterizer")  # Disables "Lost UI Shared Context GPU Error on Windows"
    self.chrome_options.add_argument("--window-size=1024x768")
    self.chrome_options.add_argument("--log-level=3")  # Errors Only
    self.chrome_options.add_argument("--incognito")  # Keeps history and logs clear
    self.chrome_options.add_argument("--no-sandbox")
    self.chrome_options.add_argument("--mute_audio")  # No loud surprises!
    self.chrome_options.add_argument("--no-gpu")  # Disables gpu-based errors (headless)

    self.driver = webdriver.Chrome(chrome_options=self.chrome_options)
