Redhat trying to use pip ImportError: No module named pip

Question

I am trying to use pip on my Redhat system.

I installed pip following the instructions here, but when I try to use it, for example pip install, I get the following error code:

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 7, in ?
    from pip import main
ImportError: No module named pip

Answer 1

this issue due to common user do not have privilege to access packages py file.
1. root user can run 'pip list'
2. other common user cannot run 'pip list'

[~]$ pip list
Traceback (most recent call last):
  File "/usr/bin/pip", line 7, in <module>
    from pip._internal import main
ImportError: No module named pip._internal

solution : root user login and run

chmod -R 755 /usr/lib/python2.7

fix this issue.
