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******
