安装pip后没有名为'pip'的模块

Question

有没有人处于相同的情况？

$ which pip 
    /usr/local/bin/pip 
    $pip 
    Traceback (most recent call last): 
     File "/usr/local/bin/pip", line 7, in <module> 
     from pip import main 
    ModuleNotFoundError: No module named 'pip' 
    $ python 
    Python 2.7.6 (default, Oct 26 2016, 20:30:19) 
    [GCC 4.8.4] on linux2 
    Type "help", "copyright", "credits" or "license" for more information. 
    >>> import pip 
    >>> pip.__version__ 
    '9.0.1' 

同样的情况发生在其他包

$ easy_install 
    Traceback (most recent call last): 
     File "/usr/local/bin/easy_install", line 7, in <module> 
     from setuptools.command.easy_install import main 
    ModuleNotFoundError: No module named 'setuptools' 
    $ virtualenv 
    Traceback (most recent call last): 
     File "/usr/local/bin/virtualenv", line 7, in <module> 
     from virtualenv import main 
    ModuleNotFoundError: No module named 'virtualenv'
