python3 与 pip3 安装与使用

 

正文开始:

1. yum -y install openssl*

(pip依赖ssl环境)

2.编译安装python3

下载地址:https://www.python.org/ftp/python/

 tar zxvf Python-3.5..tgz
 cd Python-3.5.
 ./configure
 make && make install 

安装步骤

3.安装完成后默认就有pip3了.

 

4.安装完成可以装个模块试试

 [root@localhost Python-3.5.]# pip3 install pymysql
 Collecting pymysql
   Downloading PyMySQL-0.7.-py3-none-any.whl (78kB)
     % |████████████████████████████████| 81kB .3kB/s
 Installing collected packages: pymysql
 Successfully installed pymysql-0.7.
 You are using pip version 8.1., however version 9.0. is available.
 You should consider upgrading via the 'pip install --upgrade pip' command.

上面提示有新版本了  可以升级.

使用它提示的命令就可以升级pip3了..

但是注意要把pip命令替换成pip3

 [root@localhost Python-3.5.]# pip3 install --upgrade pip
 Collecting pip
   Downloading pip-9.0.-py2.py3-none-any.whl (.3MB)
     % |████████████████████████████████| .3MB .2kB/s
 Installing collected packages: pip
   Found existing installation: pip 8.1.
     Uninstalling pip-8.1.:
       Successfully uninstalled pip-8.1.
 Successfully installed pip-9.0.
 [root@localhost Python-3.5.]# pip3 --version
 pip 9.0. from /usr/local/lib/python3./site-packages (python 3.5)

升级完成

PS:

如果使用pip3安装插件的时候提示:

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

是因为系统缺少openssl-devel包

yum install openssl-devel -y  安装一下即可.

再按照上面的方法重新 编译一下即可.

如果觉得还不错..打开支付宝领个红包吧~~
