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

或

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

pip search <搜索关键字>
