安装软件时,我的终端收到了一条消息: You are using pip version 8.1.1, however version 10.0.0 is available. You should consider upgrading via the 'pip install --upgrade pip' command.

所以我升级了pip版本: $ pip install --upgrade pip

现在我收到此错误:

~$ pip install ipython
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    from pip import main
ImportError: cannot import name main
