根据paramiko官网的指示，可以使用pip安装paramiko模块默认安装最新的稳定版本的paramiko
使用pip安装paramiko
sudo pip3 install paramiko出现一堆错误信息：

Command python setup.py egg_info failed with error code 1 in /tmp/pip_build_root/pynacl
Storing debug log for failure in /home/liuxin/.pip/pip.log
查看错误日志时发现一条信息：
No package 'libffi' found所以使用下面安装libffi:
sudo apt-get install libffi-dev再次使用pip3安装paramiko模块又提示如下错误：
error in cryptography setup command: Invalid environment marker: python_version < '3'别灰心，出现别的错误说明有进展
上网搜了一下这个错误找到一个解决方案：https://github.com/ansible/ansible/issues/31741
看到没？它也在安装libffi，至少说明我们的方向没有错， 按照大神的提示执行一下指令：
sudo pip3 install --upgrade setuptools
sudo apt-get install libffi-dev libssl-dev再次安装paramiko
sudo pip3 install paramiko安装成功，打开python3解释器测试模块：
Successfully installed paramiko pyasn1 bcrypt cryptography pynacl cffi idna asn1crypto pycparser

>>> import paramiko

ok， 搞定
总结：
在使用pip3安装paramiko模块执行以下指令：
sudo pip3 install --upgrade setuptools
sudo apt-get install libffi-dev libssl-dev
sudo pip3 install paramiko
