Ubuntu16.04下配置python3环境
1.默认使用python3.6
首先按照教程[]安装python3.6环境。
配置环境：
# 默认python3
echo "alias python=python3" | sudo tee -a /etc/profile
echo "alias python=python3" | tee -a ~/.bashrc
# 默认pip3
echo "alias pip=pip3" | sudo tee -a /etc/profile
echo "alias pip=pip3" | tee -a ~/.bashrc
# 激活配置
source /etc/profile
source ~/.bashrc
2.修改pypi源
新建pip.conf文件
mkdir ~/.pip
vim ~/.pip/pip.conf
pip.conf中添加内容：
[global]
index-url = http://pypi.mirrors.ustc.edu.cn/simple/
[install]
trusted-host=pypi.mirrors.ustc.edu.cn
