Selenium和Geckodriver的路径问题

Question

#! python3
from selenium import webdriver
browser = webdriver.Firefox()

并得到以下错误消息：

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)

    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:

我找到了一个似乎可以解决我的问题的答案：使用Python-GeckoDriver可执行文件的Selenium需要在PATH中

但我不太明白如何操作计算机中的路径或如何以计算机工作的方式组织我的文件。

我也犯了同样的错误，下面是步骤：

从以下链接下载geckodriver for MacOS：

echo $PATH

通常路径是/usr/local/bin。

将geckodriver从下载文件夹复制到步骤2中获得的路径。使用以下命令：

cp downloads /usr/local/bin 

注意：有时在执行第3步时，您可能会得到一个权限拒绝错误，要解决此错误，您应该在命令前面使用sudo，如下所示：

sudo cp downloads /usr/local/bin
