pip3 基本使用
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | 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 python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple uvicorn python3 -m pip install -i https://mirrors.aliyun.com/pypi/simple docker 阿里云 http://mirrors.aliyun.com/pypi/simple/ 中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/ 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
1 2 3 4 | 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
1 2 3 | 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
1 2 3 4 5 | 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
1 2 3 4 5 | 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 |
