WebDriverException:未知错误:对于较旧版本的Google Chrome，无法在Python中使用Selenium找到Chrome二进制错误 [英] WebDriverException: unknown error: cannot find Chrome binary error with Selenium in Python for older versions of Google Chrome

问题描述

出于兼容性原因，我更喜欢将Chrome版本55.0.2883.75与Chromedriver v.2.26一起使用.我从 https://www.slimjet.com下载了旧版的chrome./chrome/google-chrome-old-version.php 和

For compatibility reasons I prefer to use Chrome version 55.0.2883.75 with Chromedriver v. 2.26. I downloaded the older version of chrome from https://www.slimjet.com/chrome/google-chrome-old-version.php and Chromedriver 2.26 from https://chromedriver.storage.googleapis.com/index.html?path=2.26/.

我正在使用以下代码尝试设置我的Chrome二进制位置:

I am using the following code to attempt to set my Chrome binary location:

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

options = Options()
options.binary_location = "C:\\Program Files\\Chrome\\chrome64_55.0.2883.75\\chrome.exe"
driver = webdriver.Chrome('chromedriver.exe', chrome_options = options)

但是，当我尝试启动WebDriver Python时，返回以下错误:

However, when I attempt to launch the WebDriver Python returns the following error:

WebDriverException: unknown error: cannot find Chrome binary
(Driver info: chromedriver=2.26.436362

推荐答案

此错误消息...

WebDriverException: unknown error: cannot find Chrome binary

...表示 ChromeDriver 无法在系统默认位置找到 Chrome 二进制文件.

...implies that the ChromeDriver was unable to find the Chrome binary in the default location for your system.

根据> ChromeDriver-要求 :

ChromeDriver 服务器希望您将Chrome安装在每个系统的默认位置，如下所示:

The ChromeDriver server expects you to have Chrome installed in the default location for each system as follows:

¹ 对于Linux系统， ChromeDriver 期望/usr/bin/google-chrome是与实际 Chrome二进制文件的符号链接 >.

¹ For Linux systems, the ChromeDriver expects /usr/bin/google-chrome to be a symlink to the actual Chrome binary.

但是，您也可以按如下方式覆盖默认的 Chrome二进制位置:

However you can also override the default Chrome binary location as follows:

要使用通过 ChromeDriver v2.26 安装在非标准位置的 Chrome版本55.x ，可以使用以下代码块:

To use Chrome version 55.x installed in non standard location through ChromeDriver v2.26 you can use the following code block :

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

options = Options()
options.binary_location = "C:\\Program Files\\Chrome\\chrome64_55.0.2883.75\\chrome.exe"
driver = webdriver.Chrome(chrome_options = options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://google.com/')
print("Chrome Browser Invoked")
driver.quit()
