如何将geckodriver放入PATH？

Question

我在OS Sierra上,我正在运行Python 3.5.2.我安装了selenium,我正在关注一本名为"使用Python自动执行无聊任务"的书

我的代码是

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. 

我已经广泛搜索了我的问题的解决方案.许多人都有同样的问题..但没有一个解决方案正在发挥作用.我在我的Python文件夹中随处复制了geckodriver.我尝试使用终端,我已经尝试在代码中指定路径,它仍然给我错误.我希望有人可以帮助我.如果格式错误,我很抱歉,我不知道我在做什么.

Answer 1

我遇到了同样的问题,这就是我修复它的方法:

1. geckodriver从这里下载
2. 解压缩并解压缩并将geckodriver文件移动到/usr/local/bin/目录
3. 用selenium Firefoxwebdriver 运行python程序.

Answer 2

这个答案可以通过谷歌搜索“将程序添加到路径”轻松解决

export PATH=$PATH:/path/to/geckodriver
