Can't install Selenium WebDriver with Python
我正在尝试在Mac上安装Selenium WebDriver和Python。我用了这个命令：
1 | sudo easy_install selenium |
之后，我尝试了以下简单的测试：
Python
1 2 | from selenium import webdriver driver = webdriver.Firefox() |
我得到了以下错误。我做错什么了？
Traceback (most recent call last):
File"", line 1, in
File"/Library/Python/2.7/site-packages/selenium-3.0.0.b3-py2.7.egg/selenium/webdriver/firefox/webdriver.py", line 68, in init
self.service.start() File"/Library/Python/2.7/site-packages/selenium-3.0.0.b3-py2.7.egg/selenium/webdriver/common/service.py", line 71, in start
os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.
如果不带任何参数调用Selenium驱动程序，则WebDriver可执行文件的路径必须位于系统路径环境变量中。
或者，可以显式指定路径，如下所示：
1 | driver = webdriver.Firefox("path/to/the/FireFoxExecutable") |
错误是告诉您找不到
下面的shell脚本将从Mozilla的repo下载最新的geckoDriver，并将其放在
