ubuntu16.04安装phantomJs问题（ubuntu16安装python3.8）

直接apt-get install phantomjs 会安装不全

可能会报错

Message: Error - Unable to load Atom 'find_element' from file ':/ghostdriver/./third_party/webdriver-atoms/find_element.js'

解决方法，卸载后，wget安装

1. apt purge phantomjs
2. wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2
3. tar xvjf phantomjs-2.1.1-linux-x86_64.tar.bz2
4. cp phantomjs-2.1.1-linux-x86_64/bin/phantomjs /usr/bin/
