如何将geckodriver放入路径？[副本]

Question

我在OS Sierra上运行Python3.5.2。我已经安装了selenium，我正在阅读一本名为“用Python自动化无聊的任务”的书。

我的密码是

from selenium import webdriver
>>> browser = webdriver.Firefox()

我一直收到错误

Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/selenium/webdriver/common/service.py", line 64, in start
stdout=self.log_file, stderr=self.log_file)
File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py", line 947, in __init__
restore_signals, start_new_session)
File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py", line 1551, in _execute_child
raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
browser = webdriver.Firefox()
File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/selenium/webdriver/firefox/webdriver.py", line 135, in __init__
self.service.start()
File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/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. 

我已经广泛地寻找解决我的问题的方法。很多人都有同样的问题。但没有一个解决方案奏效。我已经在我的Python文件夹中到处复制了geckodriver。我试过使用terminal，也试过在代码中指定路径，但它仍然给我错误。我希望有人能帮我。对不起，如果这是在错误的格式，我不知道我在做什么。

我遇到了同样的问题，下面是我如何解决的：

1. 从此处下载GeckoDriver
2. 解压缩并将geckodriver文件移动到/usr/local/bin/目录
3. 使用seleniumFirefoxWebDriver运行python程序。
