Ubuntu16.04安装Python环境

1.安装Python3.6环境
在Ubuntu中安装Python版本的方法有很多种，这里暂时给大家写一下根据源码来安装

打开终端，顺序输入下面命令

wget http://www.python.org/ftp/python/3.6.4/Python-3.6.4.tgz
tar -xvzf Python-3.6.4.tgz
cd Python-3.6.4
./configure –with-ssl
make
sudo make install

如果安装之后出现提示则是缺少依赖包

zipimport.ZipImportError: can’t decompress data; zlib not available
Makefile:1079: recipe for target ‘install’ failed
make: *** [install] Error 1

执行下面命令

sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev

执行完毕后重新make install

2.安装Python编译外部模块文件使用的Python-dev
sudo apt-get install python-dev

3.安装包管理PIP
sudo apt-get install python-pip
安装之后升级pip
sudo pip3 install –upgrade pip

如果在搞pip的过程中出现下面的问题，则使用命令sudo python3 -m pip uninstall pip && sudo apt install python3-pip –reinstall解决

Traceback (most recent call last):
File “/usr/bin/pip3”, line 9, in <module>
from pip import main
ImportError: cannot import name ‘main’

pip3：

sudo apt-get install pip3或者sudo apt-get install python3-pip
