python - 无法在 Windows 7 中使用 Python 启动 PhantomJS

Question

我正在尝试在我的 Windows 7 中将 PhantomJS 与 Python 结合使用，但无法正常工作!这是我尝试做的。

首先，我安装了 webdriver。在下面的代码中，Firefox 正常打开，所以我相信 webdrive 已正确安装。

from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://seleniumhq.org/')

然后，我从官网下载了PhantomJS，解压后放到c:\Phantomjs。然后我将它添加到环境变量中。这是里面的东西:

C:\Phantom\phantomjs-2.0.0-windows\bin

因此，当我在终端中输入“phantomjs”时，它会正常启动。但是下面的代码给我一个错误:

from selenium import webdriver
browser = webdriver.PhantomJS( )

错误信息:

Exception ignored in: > Traceback (most recent call last): File "c:Python34\lib\site-packages\selenium\webdriver\common\service.py", line 136, in del File "c:Python34\lib\site-packages\selenium\webdriver\common\service.py", line 124, in stop AttributeError: 'NoneType' object has no attribute 'close'

在这里，如果我稍微更改一下代码:

from selenium import webdriver
browser = webdriver.PhantomJS(executable_path='C:\Phantom\phantomjs-2.0.0-windows\bin\phantomjs.exe')

错误信息:

Traceback (most recent call last):

restore_signals, start_new_session)

File "c:Python34\lib\subprocess.py", line 1112, in _execute_child startupinfo)

FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

File "c:Python34\lib\site-packages\selenium\webdriver\common\service.py", line 117, in stop

if self.process is None:

AttributeError: 'Service' object has no attribute 'process'

我该如何解决？

Answer 1

问题是您的路径中缺少exe 扩展名。

试试这个:

from selenium import webdriver
phantomjs_path = r'C:\Phantom\phantomjs-2.0.0-windows\bin\phantomjs.exe'
browser = webdriver.PhantomJS(phantomjs_path)
