##centos7 python3.5 下安装paramiko



---

###对对对

**安装开发包**  





     yum install openssl openssl-devel python-dev -y  





**安装pip前需要前置安装setuptools**  



    wget --no-check-certificate  https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26

    

    tar -zxvf setuptools-19.6.tar.gz

    

    cd setuptools-19.6

    

    python3 setup.py build

    

    python3 setup.py install



**报错： RuntimeError: Compression requires the (missing) zlib module**  



我们需要在linux中安装zlib-devel包，进行支持。



    



需要对python3.5进行重新编译安装。



    cd python3.5

    

    make & make install



又是漫长的编译安装过程。



重新安装setuptools



    python3 setup.py build

    

    python3 setup.py install



2、安装pip



    wget --no-check-certificate  https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb

    

    tar -zxvf pip-8.0.2.tar.gz

    

    cd pip-8.0.2

    

    python3 setup.py build

    

    python3 setup.py install



**安装pycrypto**



 



     $ tar -zxvf pycrypto-2.0.1.tar.gz

    

     $ cd pycrypto-2.0.1

    

     $ python setup.py build

    

     $ sudo python setup.py install



 



**安装paramiko**



     $ tar -zxvf paramiko-1.7.6.tar.gz

    

     $ cd paramiko-1.7.6

    

     $ python setup.py build

    

     $ sudo python setup.py install



**运行报错**

**解决方案**



    pip3 install cryptography
