centos7 python2.7下安装paramiko模块
1.资源准备
(1)下载源码paramiko安装包
(2)下载paramiko安装包的依赖包：pycrypto安装包和gcc包 (gcc包用yum安装)
2.安装
(1)gcc包安装
yum -y install gcc
(2)pycrypto包安装（版本pycrypto-2.6.1）
将源码安装包放到当前家目录下
tar xvzf pycrypto-2.6.1.tar.gz
cd pycrypto-2.6.1.tar.gz
python setup.py build && python setup.py install
******报错******
src/MD2.c:31:20: 致命错误：Python.h：没有那个文件或目录
#include "Python.h"
^
编译中断。
error: command 'gcc' failed with exit status 1
提示缺少Python.h文件
解决办法：yum install python-devel.x86_64
提示“gcc" failed with exit status 1
解决办法：yum -y install python-devel
然后重新安装pycrypto包
(3)安装paramiko包
将源码安装包放到当前家目录下
tar xvzf paramiko-2.4.0.tar.gz
cd paramiko-2.4.0.tar.gz
python setup.py build && python setup.py install
提示错误：error: Installed distribution cffi 0.8.6 conflicts with requirement cffi>=1.4.1
下载安装cffi ：https://pypi.python.org/pypi/cffi/
ar -xzvf cffi-1.8.2.tar.gz
cd cffi_1.8.2
python setup.py build
提示错误：fatal error: ffi.h: No such file or directory
解决办法：yum install libffi-devel
python setup.py install
提示错误：fatal error: openssl/opensslv.h: No such file or directory
解决办法 yum install openssl-devel
python setup.py install
然后再安装 paramiko
如果安装遇到error in cryptography setup command: Invalid environment marker: python_version < '3'
解决办法：sudo pip install --upgrade setuptools
sudo yum install libffi-devel
安装完后在python2.7中 import paramiko
******报错******
