2.下载多个文件
比如下载 django 1.8.11版本和simplejson 3.14.0版本的包
那么就将所需的包写入 requirement.txt
那么我的requirement.txt内容就是：
django==1.8.11
simplejson==3.14.0
如果还需要其他的包可以依次写，注意一定要写清楚自己所需的版本号避免使用的时候出错。
例如：想将包放在\home\packs目录下
那么就在命令行窗口输入：pip download -d \home\packs -r requirement.txt
3.离线安装
下载指定的包到指定文件夹。
pip list #查看安装的包
pip freeze > requirements.txt 将已经通过pip安装的包的名称记录到 requirements.txt文件
安装指定的离线包
pip install --no-index --find-links=d:/python27/packs/ falsk ##安装单个包
pip install --no-index --find-links=d:/python27/packs/ -r requirements.txt ##安装多个包
