python3 安装 pip3 (centos6.5)

2018-08-25

首先系统自带的python是python2

我们需要安装一个python3 pip3

安装python

1.安装环境

# yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-develreadline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

2.下载包

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

3.解压包

 tar -zxvf Python-3.6.1.tgz

4.创建安装目录，进入解压后的包，制定安装路径进行安装

mkir -p /usr/local/python3

cd Python-3.6.1

/configure --prefix=/usr/local/python3

5.编译安装

make && make install

6.创建软连接

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

这样在命令行中输入python代表python2，输入python3代表python3

安装pip3

1.首先安装setuptools

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.tar.gz

python3 setup.py build

python3 setup.py install

2.安装pip3

wget --no-check-certificate  https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb

tar -zxvf pip-8.0.2.tar.gz

cd pip-8.0.2

python3 setup.py build

python3 setup.py install

3.安装完成之后我们再来看下python的bin目录下都有什么东西吧，发现有pip3

创建软连接

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