Python3环境部署

环境部署

我们在pycharm上都是自己设置的python3解释器的环境变量,使得代码能够正常执行!可是怎么能让我们的python代码在LINUX上跑起来呢? linux是内置python,可是内置的是python2哦,python2在2020年就不维护了,所以python3必然大趋所示,哈哈,还是说怎么部署python3环境吧!!!!

安装python3步骤

• 1.首先解决依赖环境,这个特别重要

  #### ---yum 安装以下依赖--- ####
  # yum -y groupinstall "Development tools"
  # yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
  # yum install libffi-devel -y

• 2.下载地址：https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tgz

  wget  https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tgz
  
  #直接执行

• 3.下载压缩包后解压它

  tar -xvf  Python-3.6.2.tgz
  
  #解压后显示一个Python-3.6.2的目录/文件夹

• 4.开始编译安装

  # mkdir -p /usr/local/python3 #创建编译安装目录
  # cd Python-3.6.2
  # ./configure --prefix=/usr/local/python3
  # make && make install

• 5.创建软连接

  # ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
  # ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3

• 验证

  # python3 -V
  # pip3 -V 

 pip 安装第三方库

#清华源普遍安装速度较快
# pip install -i https://pypi.tuna.tsinghua.edu.cn/simple xxx
