TypeError：__ init __（）得到了一个意外的关键字参数＆＃39; log_path＆＃39;

Question

我想使用selenium和phantomjs生成屏幕截图。这是我从virtualenv（Python 2.7，Windows 8）执行的代码：

from selenium import webdriver
br = webdriver.PhantomJS(executable_path='C:\phantomjs\phantomjs.exe')
br.set_window_size(1376,768)
br.get('http://www.stackoverflow.com')
br.save_screenshot('screenshot.png')
br.quit()

但是我收到了这个错误：

Traceback (most recent call last):
File "C:\bunker\Lib\site-packages\custom_scn.py", line 58, in <module>
br = webdriver.PhantomJS(executable_path='C:\phantomjs\phantomjs.exe')
File "C:\bunker\Lib\site-packages\selenium\webdriver\phantomjs\webdriver.py", line 49, in   __init__
service_args=service_args,log_path=service_log_path)
TypeError: __init__() got an unexpected keyword argument 'log_path'

PhantomJs位于路径C:\phantomjs\phantomjs.exe。如何进行调试:(

Answer 1

尝试将log_path的值设置为：

log_path = os.devnull
