pip安装软件与yum安装软件是不兼容的，同一个软件包如果用pip已经安装过了，再使用yum安装则会报错，在涉及yum安装的包有依赖时要特别注意

CentOS7 yum 安装 pip3 和 python3

步骤

yum install python3
#上面的命令会自动安装python3、pip3

更新pip3

python3 -m pip install --upgrade pip setuptools wheel -i https://mirrors.aliyun.com/pypi/simple/
# python3 -m pip --version
pip 20.2.4 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)

# python3 --version ==> Python 3.6.8
# pip3 --version    ==> pip 9.0.3 from /usr/lib/python3.6/site-packages (python 3.6)

pip3 常用包

python3 -m pip list
python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple requests
python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple paramiko
python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple flask

python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple python-dotenv
python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple pipenv

python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple flask
python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple PyMySQL

python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple kafka-python

python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple fastapi

豆瓣(douban) http://pypi.douban.com/simple/
清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/

更换为国内下载源

国内源

阿里云 https://mirrors.aliyun.com/pypi/simple/
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/
豆瓣(douban) https://pypi.douban.com/simple/
清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/

一般都用https，http可能报错

命令行直接添加

python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple requests
如果提示不信任，则
python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com requests

python2 同理

修改配置文件

cat ~/.pip/pip.conf #没有这个文件则创建之
[global]
index-url = http://pypi.douban.com/simple
[install]
trusted-host=pypi.douban.com

requirements.txt

pip的freeze命令用于生成将当前项目的pip类库列表生成 requirements.txt 文件：
pip freeze > requirements.txt

安装requirements.txt中的类库内容
pip install -r requirements.txt
