准备
在断网的和联网的机器安装pip，下载地址http://pypi.python.org/pypi/pip
在联网的开发机器上安装好需要的包
例如：
pip3 install paramiko pip3 install fabric
打包已安装的包
新建pyenv文件夹用来存储下载下来的所需安装包
pip3 list #查看安装的包 #使用pip导出当前环境所有依赖包信息文件 pip3 freeze >requirements.txt # 下载所有依赖包到本地 pip3 install -r requirements.txt -d /root/pyenv/ # pip10使用 pip download -d C:\Users\pyenv -r requirements.txt
在其他环境下(相同的系统环境)安装所有依赖
$ pip install --no-index --find-links=/home/pyenv -r requirements.txt Collecting asn1crypto==0.24.0 (from -r requirements.txt (line 1)) Collecting bcrypt==3.1.4 (from -r requirements.txt (line 2)) Collecting certifi==2018.4.16 (from -r requirements.txt (line 3)) Collecting cffi==1.11.5 (from -r requirements.txt (line 4)) Collecting chardet==3.0.4 (from -r requirements.txt (line 5)) Collecting cryptography==2.2.2 (from -r requirements.txt (line 6)) Requirement already satisfied: fabric==2.0.1 in /home/ap/tscms/anaconda3/lib/python3.6/site-packages/fabric-2.0.1-py3.6.egg (from -r requirements.txt (line 7))
