使用命令行选项运行selenium Webdriver时出现python异常

Question

我有以下这段代码来调用带有扩展名的chrome浏览器：

    path_to_extension = path.abspath(r'C:\temp\ublock_extension_1_21_6_0.crx')
    path_to_extension = str(path_to_extension)
    chrome_options = Options()
    chrome_options.add_argument(str('load-extension=') + path_to_extension)

    self._wd = webdriver.Chrome(chrome_options)
    self._wd.create_options()

当我执行这段代码时，我得到以下堆栈跟踪：

Traceback (most recent call last):
  File "seleniumtest.py", line 43, in __init__
    self._wd = webdriver.Chrome(chrome_options)
  File "c:\python27\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 73, in __init__
    self.service.start()
  File "c:\python27\lib\site-packages\selenium\webdriver\common\service.py", line 76, in start
    stdin=PIPE)
  File "c:\python27\lib\subprocess.py", line 394, in __init__
    errread, errwrite)
  File "c:\python27\lib\subprocess.py", line 599, in _execute_child     
    args = list2cmdline(args)
  File "c:\python27\lib\subprocess.py", line 266, in list2cmdline       
    needquote = (" " in arg) or ("\t" in arg) or not arg
TypeError: argument of type 'Options' is not iterable```

It looks like passing chrome options to the selenium webdriver seems to croak the subprocess. Any idea how I can fix this?

使用以下代码：

path_to_extension = path.abspath（r'C：\\ temp \\ ublock_extension_1_21_6_0.crx'）

path_to_extension = str（path_to_extension）

选项= webdriver.ChromeOptions（）

chrome_options.add_argument（str（'load-extension ='）+ path_to_extension）

self._wd = webdriver.Chrome（options = options）

self._wd.create_options（）
