如何禁用或更改ghostdriver.log的路径？

Question

问题很简单，但一些上下文可能会有所帮助。

我尝试在使用selenium和phantomjs作为下载器的同时部署scrapy。但问题是，在尝试部署时，它一直在说权限被拒绝。所以我想更改ghostdriver.log的路径，或者直接禁用它。看着phantomjs -h和ghostdriver github页面，我找不到答案，我的朋友谷歌也让我失望。

使用PhantomJS驱动程序时，添加以下参数：

driver = webdriver.PhantomJS(service_log_path='/var/log/phantomjs/ghostdriver.log')

相关代码，如果能有一个关闭日志的选项就更好了，但似乎不支持：

selenium/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')

Answer 2

    #Reduce logging level
    driver = webdriver.PhantomJS(service_args=["--webdriver-loglevel=SEVERE"])

    #Remove logging
    import os
    driver = webdriver.PhantomJS(service_log_path=os.path.devnull)
