ChromeDriver: Custom Chrome Executable Path

问题

I'm using the portable version of Google Chrome.

Since WebDriver expects the default installation path, it does not find the portable one which obviously is at another location:

Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: cannot find Chrome binary
  (Driver info: chromedriver=2.9.248315,platform=Windows NT 6.1 SP1 x86_64) (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 11.13 seconds
Build info: version: '2.35.0', revision: '8df0c6b', time: '2013-08-12 15:43:19'
System info: os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.8.0_05'
Driver info: org.openqa.selenium.chrome.ChromeDriver

How do I set a custom path to the chrome.exe file?

回答1:

Nevermind, I found the answer myself:

ChromeOptions options = new ChromeOptions();
options.setBinary("/path/to/chrome/binary");

ChromeDriver driver = new ChromeDriver(options);

回答2:

Python version:

chromedriver = "/path/to/chromedriver"
options = Options()
options.binary_location = '/path/to/chrome'
driver = webdriver.Chrome(chromedriver, chrome_options=options)
