linux下安装python开发环境

1. 安装依赖环境

# 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      

2下载文件

https://www.python.org/downloads/

# wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz

3.安装python3

  我个人习惯安装在/usr/local/python3(具体安装位置看个人喜好)
  创建目录:

1 # mkdir -p /usr/local/python3

解压下载 的包  # tar -zxvf Python-3.6.1.tgz

4.进入解压后的目录,编译安装。

1 2 # cd Python-3.6.1 # ./configure --prefix=/usr/local/python3
make install    或者 make && make install

5.建立python3的软链

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

6.并将/usr/local/python3/bin加入PATH

1 2 3 4 5 6 7 8 9 # vim ~/.bash_profile # .bash_profile # Get the aliases and functions if [ - f ~ / .bashrc ]; then . ~ / .bashrc fi # User specific environment and startup programs PATH = $PATH:$HOME / bin : / usr / local / python3 / bin export PATH

按ESC,输入:wq回车退出。

  修改完记得执行行下面的命令,让上一步的修改生效:

1 # source ~/.bash_profile

  检查Python3及pip3是否正常可用:

1 2 3 4 # python3 -V Python 3.6 . 1 # pip3 -V pip 9.0 . 1 from / usr / local / python3 / lib / python3. 6 / site - packages (python 3.6 )

二、安装pip以及setuptools

  毕竟丰富的第三方库是python的优势所在,为了更加方便的安装第三方库,使用pip命令,我们需要进行相应的安装。

1、安装pip前需要前置安装setuptools

命令如下:

wget –no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26

tar -zxvf setuptools-19.6.tar.gz

cd setuptools-19.6

python3 setup.py build

python3 setup.py install

2、安装pip

命令如下:

wget –no-check-certificate  https://pypi.python.org/packages/source/p/pip/pip-9.0.3.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb

tar -zxvf pip-9.0.3.tar.gz

cd pip-9.0.3

python3 setup.py build

python3 setup.py install

错误:

configure: error: no acceptable C compiler found in $PATH

需要安装gcc套件:yum install gcc

wget不是命令:yum -y install wget
