Answer 1

此错误是由pkg_resources的过期版本引起的。为了消除错误，请执行以下操作：

启动python会话，导入pkg_resources，然后查看加载它的文件：

In [1]: import pkg_resources

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

删除此文件（以及关联的*.py文件）：

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

就是这样！重新安装;它应该没有任何错误地完成：
```
$ 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！另请注意，您正在弄乱应该由apt控制的文件。
