使用Ubuntu 14.04.5 LTS.试图安装line_profiler sudo pip3 install line_profiler,现在当我运行时sudo pip3,我得到以下输出:

Traceback (most recent call last):
  File "/usr/bin/pip3", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/local/lib/python3.4/dist-packages/pkg_resources/__init__.py", line 72, in <module>
    import packaging.requirements
  File "/usr/local/lib/python3.4/dist-packages/packaging/requirements.py", line 59, in <module>
    MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")
TypeError: __call__() missing 1 required positional argument: 'name'

当我尝试运行django应用程序时遇到类似的错误,所以我猜很多东西搞砸了.

任何人都知道可能出现什么问题或如何解决？
