问题很简单，但一些内容可能会有所帮助。
我正在尝试部署 scrapy，同时使用 selenium 和 phantomjs 作为下载器。但问题是在尝试部署时它一直说权限被拒绝。所以我想更改 Ghostdriver.log 的路径或只是禁用它。看着 phantomjs -h 和 Ghostdriver github 页面我找不到答案，我的朋友 google 也让我失望。

使用PhantomJS驱动时添加以下参数：
driver = webdriver.PhantomJS(service_log_path='/var/log/phantomjs/ghostdriver.log')
相关代码，如果有一个关闭日志记录的选项就好了，但似乎不支持：
硒/webdriver/phantomjs/service.py
class Service(object):
"""
Object that manages the starting and stopping of PhantomJS / Ghostdriver
"""
def __init__(self, executable_path, port=0, service_args=None, log_path=None):
"""
Creates a new instance of the Service
:Args:
- executable_path : Path to PhantomJS binary
- port : Port the service is running on
- service_args : A List of other command line options to pass to PhantomJS
- log_path: Path for PhantomJS service to log to
"""
self.port = port
self.path = executable_path
self.service_args= service_args
if self.port == 0:
self.port = utils.free_port()
if self.service_args is None:
self.service_args = []
self.service_args.insert(0, self.path)
self.service_args.append("--webdriver=%d" % self.port)
if not log_path:
log_path = "ghostdriver.log"
self._log = open(log_path, 'w')
