出错信息如下：

During handling of the above exception, another exception occurred:

解决办法：请先下载geckodriver，下载好双击文件解压后会得到一个geckodriver文件，将此文件移动到/usr/local/bin/目录下即可。

<br />

NOTE：使用终端解压.tar.gz文件：

tar zxvf 文件路径
例如：tar zxvf ~/Downloads/geckodriver-v0.11.1-macos.tar.gz
注：不会解压到压缩文件相同目录下，会解压到终端中cd到的目录

NOTE：使用终端移动文件：

mv 文件路径 要移动到的文件夹路径
例如：sudo mv ~/Downloads/geckodriver /usr/local/bin/
