python - 无法安装python模块

Question

无法在 Ubuntu 计算机上安装 Python 模块。当我尝试安装 Paramiko 模块时，收到以下错误:

Traceback (most recent call last):
  File "/usr/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py",  line 70, in <module>
    import packaging.version
ImportError: No module named packaging.version

Answer 1

终于找到了解决方案，清理并重新安装 pip 后它就起作用了:

sudo -i
apt-get purge -y python-pip
wget https://bootstrap.pypa.io/get-pip.py
python ./get-pip.py
apt-get install python-pip
