1、使用安装包安装pip
#上python官网下载,下载页面:https://pypi.python.org/pypi/pip#downloads #下载 [root@wrx pip-9.0.1]# wget https://pypi.python.org/packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-9.0.1.tar.gz#md5=35f01da33009719497f01a4ba69d63c9 #下载完后解压 tar -zxvf pip-9.0.1.tar.gz #进入pip-9.0.1目录 [root@wrx python]# cd pip-9.0.1 #安装 [root@wrx pip-9.0.1]# python3 setup.py install
2、使用yum安装
#查询是否有相应安装包 [root@wrx python3]# yum list python-pip* #安装 [root@wrx python3]# yum install python-pip
3、更新pip
[root@wrx python3]# pip install -U pip
4、pip使用
#安装PyPI #如安装pytesseract [root@wrx pip-9.0.1]# pip install pytesseract #查看具体安装文件 [root@wrx pip-9.0.1]# pip show --files pytesseract Name: Pillow Version: 4.1.1 Summary: Python Imaging Library (Fork) Home-page: https://python-pillow.org Author: Alex Clark (Fork Author) Author-email: aclark@aclark.net License: Standard PIL License Location: /usr/local/lib/python3.4/site-packages Requires: olefile Files:……………… #查看需要更新的包 [root@wrx pip-9.0.1]# pip list --outdated #升级 [root@wrx pip-9.0.1]# pip install --upgrade pytesseract #卸载 [root@wrx pip-9.0.1]# pip uninstall pytesseract
注:
pip依赖ssl,因此在安装Python时需要安装openssl
[root@wrx Python-3.5.4]# yum -y install openssl*
