For Linux based system, download geckodriver. Extract it and copy the driver to /usr/local/bin and finally make it executable (chmod +x geckodriver).

Shortly,
不久，
From selenium 3.0, you have to explicitly download Marionette geckodriverfor Firefox (which is similar to ChromeDriver for Chrome) and keep it in a place where the system can identify it. (like System PATH - environmental variables in Windows) or specify using language options.
从 selenium 3.0 开始，您必须明确下载Marionette geckodriverFirefox（类似于 ChromeDriver for Chrome）并将其保存在系统可以识别的地方。（如系统路径 - Windows 中的环境变量）或指定使用语言选项。

Linux(Ubuntu) Users should download the geckodriver and extract it in your project folder and while running your python script give the argument as
Linux(Ubuntu) 用户应该下载 geckodriver 并将其解压缩到您的项目文件夹中，并在运行您的 python 脚本时将参数作为
executable_path="./geckodriver"
Example:
例子：
from selenium import webdriver
class RunFFTests():
def testMethod(self):
# Initiate the driver instance
driver = webdriver.Firefox(
executable_path="./geckodriver")
driver.get("http://www.letskodeit.com")
ff = RunFFTests()
ff.testMethod()
