我尝试搜索，但没有找到明确的答案。在Windows Server 2016上，没有实际安装Chrome浏览器。我下载了正确的“
chromedriver.exe”并将其放置在“ D：\ Apps \ chromedriver.exe”中。我已将完整路径添加为“ D：\ Apps \
chromedriver.exe”到我的环境PATH中。

当我尝试启动使用最新Selenium的Windows服务时，出现以下错误：

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，我是否还必须实际安装完整的浏览器，还是仅仅是在我的Python代码中找不到chromedriver.exe（以下内容完整披露）：

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)
