怎么下载旧版本的Selenium

试运行一个爬虫：

from bs4 import BeautifulSoup
from selenium import webdriver
import urllib
driver = webdriver.PhantomJS(
executable_path='/usr/local/bin/phantomjs') # 浏览器的地址 如果是windows，应该是某个exe地址
def search(keyword):
url_keyword = urllib.parse.quote(keyword)
url = "http://www.tianyancha.com/search/" + url_keyword + "?checkFrom=searchBox"
print(url)
driver.get(url)
bsObj = BeautifulSoup(driver.page_source, "html5lib")
print(bsObj)
company_list = bsObj.find_all("span", attrs={"ng-bind-html": "node.name | trustHtml"})
for company in company_list:
print(company.get_text())
if name == 'main':
search("阿里巴巴 马云")

结果第二行就告诉我：
UserWarning: Selenium support for PhantomJS has been deprecated, please use headless versions of Chrome or Firefox instead
warnings.warn('Selenium support for PhantomJS has been deprecated, please use headless '

这 不 能 忍！

赶紧下载旧版本的Selenium
在命令行运行：

pip install selenium==2.33
