Question

我一直在尝试在我的Mac上设置chromes无头浏览器但我收到错误。

我尝试按照这些教程进行参考：

https://intoli.com/blog/running-selenium-with-headless-chrome/ https://duo.com/decipher/driving-headless-chrome-with-python

并使用这些stackoflow页面

How to get Chromedriver in headless mode to run headless?和selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH error with chrome

无头浏览器工作在phantomjs但我知道selenium不再希望我们使用它。这就是我现在正在运行的:(几乎只有一个堆栈溢出的响应）

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument("--headless")
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("http://www.duo.com")
print("Chrome Browser Initialized in Headless Mode")

这是我的回答：

Traceback (most recent call last):

    driver = webdriver.Chrome(chrome_options=chrome_options)

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary
  (Driver info: chromedriver=2.36.540469 (1881fd7f8641508feb5166b7cae561d87723cfa8),platform=Mac OS X 10.13.2 x86_64)

Answer 1

错误确实给我们提示如下：

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary
  (Driver info: chromedriver=2.36.540469 (1881fd7f8641508feb5166b7cae561d87723cfa8),platform=Mac OS X 10.13.2 x86_64)

错误表明 ChromeDriver 在预期位置找不到 Chrome 二进制文件。

可以有以下两种解决方案：

根据Requirements， Chrome 安装需要位于明确的位置。

作为替代方案，您可以通过Options类的实例传递 Chrome 二进制文件的绝对路径，如下所示：

from selenium.webdriver.chrome.options import Options

options = Options()
options.binary_location = "/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome"

最后，在启动 WebDriver 和 WebClient 时，您需要发送参数 Key executable_path 使用值 chrome_path 。

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.binary_location = "/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome"
options = Options()
options.add_argument("--headless")
options.add_argument("--no-sandbox")
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
chrome_path = "/home/ec2-user/chrome/chromedriver"
driver = webdriver.Chrome(executable_path=chrome_path, chrome_options=options)
driver.get("http://www.duo.com")
print("Chrome Browser Initialized in Headless Mode")

替代

使用方法set_headless(headless=True)的可用性，以编程方式在 无头模式 中以编程方式调用 Google Chrome浏览器变得更加容易，如下所示：

文档：

set_headless(headless=True)
    Sets the headless argument

    Args:
        headless: boolean value indicating to set the headless option

示例代码：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.set_headless(headless=True)
driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get("http://google.com/")
print ("Headless Chrome Initialized")
driver.quit()
