运行parami时出现Python模块ecdsa错误

Question

我正在尝试安装paramiko模块..失败，错误如下

python ./test.py 
Traceback (most recent call last):
  File "./test.py", line 30, in <module>
    import paramiko
  File "/tmp/build-paramiko/paramiko-1.12.0/paramiko/__init__.py", line 64, in <module>
    from transport import SecurityOptions, Transport
  File "/tmp/build-paramiko/paramiko-1.12.0/paramiko/transport.py", line 45, in <module>
    from paramiko.ecdsakey import ECDSAKey
  File "/tmp/build-paramiko/paramiko-1.12.0/paramiko/ecdsakey.py", line 24, in <module>
    from ecdsa import SigningKey, VerifyingKey, der, curves
ImportError: No module named ecdsa

关于如何进行paramiko安装有什么建议吗？
