                                  download. Implied with --no-index.

    1、install

    pip install
    You must give at least one requirement to install (see "pip help install")

    所以这里可以直接使用一下命令实现在线安装

    pip install <包名> 或 pip install -r requirements.txt
    通过使用== >= <= > <来指定版本,不写则安装最新版
    
    requirements.txt内容格式为:
    
    APScheduler==2.1.2
    Django==1.5.4
    MySQL-Connector-Python==2.0.1
    MySQL-python==1.2.3
    PIL==1.1.7
    South==1.0.2
    django-grappelli==2.6.3
    django-pagination==1.0.7

    安装本地安装包

    pip install <目录>/<文件名> 或 pip install --use-wheel --no-index --find-links=wheelhouse/ <包名>

    2、uninstall 

    卸载安装包

    pip uninstall <包名> 或 pip uninstall -r requirements.txt

    升级包

    pip install -U <包名>
    
    或:pip install <包名> --upgrade

    升级pip

    pip install -U pip

    使用pip安装插件的时候报错:
    
    You are using pip version 8.1.1, however version 9.0.1 is available.
    You should consider upgrading via the 'python -m pip install --upgrade pip' command.
    
    升级命令: python -m pip install --upgrade pip

     3、freeze

    pip freeze,查看已经安装的包及版本信息。

    导出到指定文件中,如图,注意 “ > ”,文件名称随意。常见按第二种写法。

     

    4、list

     查询可升级的包

    pip list -o

    5、show

    显示包所在目录及信息

    6、search

    搜索包

    pip search <搜索关键字>
