python-selenium无法调用浏览器的问题==

一直有这个问题

问题：selenim不能调用浏览器

File "/Users/ligaijiang/PycharmProjects/Runoob/venv/lib/python3.7/site-packages/selenium/webdriver/common/service.py", line 104, in start
    raise WebDriverException("Can not connect to the Service %s" % self.path)
selenium.common.exceptions.WebDriverException: Message: Can not connect to the Service /usr/local/bin/geckodriver

现在莫名其妙的好了！
