linux安装python3
请求库
一、requests库
pipe install requests
注意：出现报错：pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
安装以下俩库:
yum install openssl
yum install openssl-devel
重新编译python3，python3默认没有支持ssl
cd Python-3.6.2
./configure --with-ssl
make
make install
二、selenium
pip3 install selenium==3.4.3（不跟版本默认安装最新版）
三、aiohttp
pip3 install aiohttp
解析库
一、lxml
pip3 install lxml
二、Beautiful Soup
pip3 install beautifulsoup4
