这是一个头脑,所以我在审查并阅读了有关此问题的所有先前帖子之后发布了这个问题.

AttributeError: 'module' object has no attribute 'packaging'

Answer 1

此错误是由于存在过时版本引起的pkg_resources.为了消除错误,请执行以下操作:

1. 启动python会话,导入pkg_resources并查看加载它的文件:

   In [1]: import pkg_resources
   
   In [2]: pkg_resources.__file__
   Out[2]: '/usr/lib/python2.7/dist-packages/pkg_resources.pyc'
   

2. 删除此文件(和相关*.py文件):

   $ sudo rm /usr/lib/python2.7/dist-packages/pkg_resources.py*
   

3. 而已!重新安装; 它应该没有任何错误完成:

   $ sudo pip install awssh
   

警告

如果您使用的是基于Debian的Linux系统,则可能已通过该python-pkg-resources软件包安装了此文件.因此,更新或重新安装此软件包将恢复过时模块!还要注意你正在搞乱一个应该被控制的文件apt.
