python ，selenium已安装好，但是运行driver=webdriver.firefox().报...

>>> from selenium import webdriver
>>> driver=webdriver.firefox()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'module' object is not callable
>>>

driver=webdriver.Firefox()注意大小写

>>> dir(webdriver)
['ActionChains', 'Android', 'BlackBerry', 'Chrome', 'ChromeOptions', 'DesiredCapabilities', 'Edge', 'Firefox', 'FirefoxProfile', 'Ie', 'Opera', 'PhantomJS', 'Proxy', 'Remote', 'Safari', 'TouchActions', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__', '__version__', 'android', 'blackberry', 'chrome', 'common', 'edge', 'firefox', 'ie', 'opera', 'phantomjs', 'remote', 'safari', 'support']

具体驱动还是要去下载的。

During handling of the above exception, another exception occurred:

这是没有驱动的报错

你需要下载一个 geckodriver.exe 这东西，然后把这个东西放在 python的安装路劲下。同样，无界面浏览器driver=webdriver.PhantomJS()需要下载phantomjs.exe 这东西放在  python的安装路劲下，例如我的python安装路劲：C:\Users\****\AppData\Local\Programs\Python\Python35，我就放在这里面
