1、install

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

所以這里可以直接使用一下命令實現(xiàn)在線安裝

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

通過使用== >= <= > <來指定版本，不寫則安裝最新版

requirements.txt內(nèi)容格式為：

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

安裝本地安裝包

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

2、uninstall

卸載安裝包

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

升級包

pip install -U <包名>

或：pip install <包名> --upgrade

升級pip

pip install -U pip

或

使用pip安裝插件的時候報錯：

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.

升級命令： python -m pip install --upgrade pip

3、freeze

pip freeze,查看已經(jīng)安裝的包及版本信息。
