python3.5 Environment Preparation

First, install the pyenv

#系统环境 # cat/etc/redhat-release CentOS Linux release 7.2.1511 (Core) 1, installing git# yum-y install GIT2, installing pyenv# curl-l https://r Aw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | Bash or reference: Https://github.com/yyuu/pyenv-installer3, config environment variable # vim/etc/profile.d/pyenv.sh #定义的全局环境变量export path= "/root /.pyenv/bin: $PATH "eval" $ (pyenv init-) "eval" $ (pyenv Virtualenv-init-) "#. /etc/profile.d/pyenv.sh #载入一下

Second, install Python

1. Install the build tool # Yum-y install gcc make patch2, install dependent environment # Yum-y install gdbm-devel openssl-devel sqlite-devel readline-devel zlib- Devel bzip2-devel3, Upgrade Pyenv (the latest version 3.2 may not be in the pyenv) # pyenv update4, installing python3.5.2# pyenv install 3.5.2 #这块可能安装比较慢, need to wait a while. 5, using the domestic image installation # mkdir ~/.pyenv/cache# wget-c http://7d9qvq.com1.z0.glb.clouddn.com/Python-3.5.2.tgz # MV python-3.5.2.tar.gz ~/.pyenv/cache/python-3.5.2.tar.gz # pyenv Install 3.5.2

Three, Pyenv basic use method

1. Local command # pyenv versions* system  (set by /root/.pyenv/version)   3.5.2 # pyenv local 3.5.2     #切换到3.5.2# python -vpython 3.5.2      #已经切换成功2, Global command # pyenv global 3.5.2  # The global switch to version 3.5, 2, is not recommended for this command 3, virtualenv command # pyenv virtualenv 3.5.2 bjwf  # Create a python3.5.2 virtual environment in 3.5.2 template bjwf# ll ~/.pyenv/versions/     3.5.2   &NBSP;&NBSP;&NBSP;BJWF&NBSP;-&GT;&NBSP;/ROOT/.PYENV/VERSIONS/3.5.2/ENVS/BJWF4, uninstall command # pyenv  uninstall bjwf     #卸载某个版本 (including virtual environment version) pyenv-virtualenv: remove /root/.pyenv/ versions/3.5.2/envs/bjwf? y# ll ~/.pyenv/versions/drwxr-xr-x 7 root root 63  jun 30 05:50 3.5.25, other commands # pyenv install –list    #列出可安装的版本  # pyenv rehash            #更新数据库  # pyenv versions           #查看当前已安装的所有版本  # pyenv global 3.5.2     # Suggest never do  # pyenv help               #查看帮助Usage:  pyenv <command> [<args>]some useful pyenv commands  are:   commands    List all available pyenv  commands   local       set or show the  local application-specific python version   global       Set or show the global Python version   shell        set or show the shell-specific python version    install     install a python version using python-build    uninstall   Uninstall a specific Python version    rehash      rehash pyenv shims  (run this after  Installing executables)    version     show the current  python version and its origin   versions    list  all Python versions available to pyenv   which        Display the full path to an executable    whence      list all python versions that contain  the given executablesee  ' pyenv help <command> '  for information  On a specifiC command.

Four, install Ipython,jupyter

1, configure the domestic mirror (pipe) # mkdir ~/.pip# vim ~/.pip/pip.conf[global]index-url = http:// MIRRORS.ALIYUN.COM/PYPI/SIMPLE/TRUSTED-HOST = MIRRORS.ALIYUM.COM2, installation Ipython# pip install  --upgrade pip    #我这块提升要先安装这个 # pip install ipyton# ipython     #可以使用了Python  3.5.2  (default, jun 30 2016, 05:24:18)  Type  " Copyright ", " credits " or " License " for more information.
