当我做pip --version时它会将错误显示为ImportError:没有名为pyparsing的模块

Question

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？

我有同样的问题,并解决了它.在这里你可以看到pip不能正常工作(没有任何附加参数).

root@notebook:/home/ci# pip
Traceback (most recent call last):
  File "/usr/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 72, in <module>
    import packaging.requirements
  File "/usr/local/lib/python2.7/dist-packages/packaging/requirements.py", line 9, in <module>
    from pyparsing import stringStart, stringEnd, originalTextFor, ParseException

好的,首先我们可以做的是安装破坏的依赖:

wget https://pypi.python.org/packages/3c/ec/a94f8cf7274ea60b5413df054f82a8980523efd712ec55a59e7c3357cf7c/pyparsing-2.2.0.tar.gz
gunzip pyparsing-2.2.0.tar.gz
tar -xvf pyparsing-2.2.0.tar
cd pyparsing-2.2.0 && python setup.py install

在它之后,依赖将从源安装.

试着再次使用pip:

root@rundeck.euovh01.un.private:/tmp/pyparsing-2.2.0# pip
Traceback (most recent call last):
  File "/usr/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 74, in <module>
    import appdirs
ImportError: No module named appdirs

这是下一个问题.你可以更快地解决它:

root@notebook:/home/ci# python -m pip install appdirs
Downloading/unpacking appdirs
  Downloading appdirs-1.4.3-py2.py3-none-any.whl
Installing collected packages: appdirs
Successfully installed appdirs
Cleaning up...

之后我的核心被成功修复了.亲切的问候.
