我也试过安装/卸载pyparsing,但它不起作用.我坚持这个,我也必须安装其他库.

这是错误消息:

Traceback (most recent call last): 
File "/usr/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
File "/home/rachana/.local/lib/python2.7/site-packages/pkg_resour??ces/__init__.py", line 72, in <module>
    import packaging.requirements
File "/home/rachana/.local/lib/python2.7/site-packages/packaging/??requirements.py", line 9, in <module>
    from pyparsing import stringStart, stringEnd, originalTextFor, ParseException
ImportError: No module named pyparsing

我怎样才能解决这个问题？
